Harmonic Mean Characteristics, Applications and Limitations

indiafreenotesby indiafreenotes0

A simple way to define a harmonic mean is to call it the reciprocal of the arithmetic mean of the reciprocals of the observations. The most important criteria for it is that none of the observations should be zero.

A harmonic mean is used in averaging of ratios. The most common examples of ratios are that of speed and time, cost and unit of material, work and time etc. The harmonic mean (H.M.) of n observations is

H.M. = 1÷ (1⁄n ∑ i= 1n (1⁄xi) )

In the case of frequency distribution, a harmonic mean is given by

H.M. = 1÷ [1⁄N (∑ i= 1n (fi ⁄ xi)], where N = ∑ i= 1n fi

Properties of Harmonic Mean

  • If all the observation taken by a variable are constants, say k, then the harmonic mean of the observations is also k
  • The harmonic mean has the least value when compared to the geometric mean and the arithmetic mean

Advantages of Harmonic Mean

  • A harmonic mean is rigidly defined
  • It is based upon all the observations
  • The fluctuations of the observations do not affect the harmonic mean
  • More weight is given to smaller items

Disadvantages of Harmonic Mean

  • Not easily understandable
  • Difficult to compute

Geometric Mean Characteristics, Applications and Limitations

indiafreenotesby indiafreenotes0

A geometric mean is a mean or average which shows the central tendency of a set of numbers by using the product of their values. For a set of n observations, a geometric mean is the nth root of their product. The geometric mean G.M., for a set of numbers x1, x2, … , xn is given as

G.M. = (x1. x2 … xn)1⁄n

or, G. M. = (π i = 1n xi) 1⁄n = n√( x1, x2, … , xn).

The geometric mean of two numbers, say x, and y is the square root of their product x×y. For three numbers, it will be the cube root of their products i.e., (x y z) 1⁄3.

Properties of Geometric Means

  • The logarithm of geometric mean is the arithmetic mean of the logarithms of given values
  • If all the observations assumed by a variable are constants, say K >0, then the G.M. of the observation is also K
  • The geometric mean of the ratio of two variables is the ratio of the geometric means of the two variables
  • The geometric mean of the product of two variables is the product of their geometric means

Advantages of Geometric Mean

  • A geometric mean is based upon all the observations
  • It is rigidly defined
  • The fluctuations of the observations do not affect the geometric mean
  • It gives more weight to small items

Disadvantages of Geometric Mean

  • A geometric mean is not easily understandable by a non-mathematical person
  • If any of the observations is zero, the geometric mean becomes zero
  • If any of the observation is negative, the geometric mean becomes imaginary

Arithmetic Mean: Characteristics, Applications and Limitations

indiafreenotesby indiafreenotes0

The arithmetic mean,’ mean or average is calculated by summ­ing all the individual observations or items of a sample and divid­ing this sum by the number of items in the sample. For example, as the result of a gas analysis in a respirometer an investigator obtains the following four readings of oxygen percentages:

14.9

10.8

12.3

23.3

___________

Sum=61.3

He calculates the mean oxygen percentage as the sum of the four items divided by the number of items—here, by four. Thus the average oxygen percentage is

Mean = 61.3 / 4 =15.325%

Calculating a mean presents us with the opportunity for learning statistical symbolism. An individual observation is symbo­lized by Yi, which stands for the ith observation in the sample. Four observations could be written symbolically as Yi, Y2, Y3, Y4.

We shall define n, the sample size, as the number of items in a sample. In this particular instance, the sample size n is 4. Thus, in a large sample, we can symbolize the array from the first to the nth item as follows: Y1, Y2…, Yn. When we wish to sum items, we use the following notation:

The capital Greek sigma, Ʃ, simply means the sum of items indica­ted. The i = 1 means that the items should be summed, starting with the first one, and ending with the nth one as indicated by the i = n above the Ʃ. The subscript and superscript are necessary to indicate how many items should be summed. Below are seen increasing simplifications of the complete notation shown at the extreme left:

Properties of Arithmetic Mean:

  1. The sum of deviations of the items from the arithmetic mean is always zero i.e.

∑(X–X) =0.

  1. The Sum of the squared deviations of the items from A.M. is minimum, which is less than the sum of the squared deviations of the items from any other values.
  2. If each item in the series is replaced by the mean, then the sum of these substitutions will be equal to the sum of the individual items.                       

Merits of A.M:

  1. It is simple to understand and easy to calculate.
  2. It is affected by the value of every item in the series.
  3. It is rigidly defined.
  4. It is capable of further algebraic treatment.
  5. It is calculated value and not based on the position in the series.

Demerits of A.M:

  1. It is affected by extreme items i.e., very small and very large items.
  2. It can hardly be located by inspection.
  3. In some cases A.M. does not represent the actual item. For example, average patients admitted in a hospital is 10.7 per day.
  4. A.M. is not suitable in extremely asymmetrical distributions.

Meaning and Objectives of Measures of Central Tendency

indiafreenotesby indiafreenotes0

Central Tendency is a statistical concept that identifies the central or typical value within a dataset, representing its overall distribution. It provides a single summary measure to describe the dataset’s center, enabling comparisons and analysis. The three primary measures of central tendency are:

  1. Mean (Arithmetic Average): The sum of all values divided by the number of values.
  2. Median: The middle value when data is ordered, dividing it into two equal halves.
  3. Mode: The most frequently occurring value in the dataset.

Objectives of Measures of Central Tendency:

Measures of central tendency are statistical tools used to summarize and describe a dataset by identifying a central value that represents the data. These measures include the mean, median, and mode, each serving specific objectives to aid in data analysis.

  1. Summarizing Data

The primary objective is to condense a large dataset into a single representative value. By calculating a central value, such as the mean, median, or mode, the complexity of raw data is reduced, making it easier to understand and interpret.

  1. Identifying the Center of Distribution

Central tendency measures aim to determine the “center” or most typical value of a dataset. This central value acts as a benchmark around which data points are distributed, providing insights into the dataset’s overall structure.

  1. Facilitating Comparisons

These measures allow comparisons between different datasets. For instance, comparing the mean income of two cities or the average performance of students across different schools can reveal relative trends and patterns.

  1. Assisting in Decision-Making

Measures of central tendency provide essential information for making informed decisions. In business, knowing the average sales or customer preferences helps managers formulate strategies, allocate resources, and predict outcomes.

  1. Assessing Data Symmetry and Distribution

The relationship between the mean, median, and mode can indicate the skewness of the data. For example:

  • In symmetric distributions: Mean = Median = Mode.
  • In positively skewed distributions: Mean > Median > Mode.
  • In negatively skewed distributions: Mean < Median < Mode.

This helps in understanding the nature and spread of the dataset.

  1. Comparing Groups within Data

Central tendency measures are crucial for comparing subsets within a dataset. For example, the average test scores of different age groups in a population can be compared to identify performance trends.

  1. Highlighting Data Trends

These measures provide insights into recurring trends or patterns. For example, the mode identifies the most common value, which is useful in market research to understand consumer preferences.

  1. Forming the Basis for Further Analysis

Central tendency measures serve as the foundation for advanced statistical analyses, such as variability, correlation, and regression. They provide an initial understanding of the dataset, guiding further exploration.

Tabulation and Presentation: Meaning, objectives and Types of Classification

indiafreenotesby indiafreenotes0

Tabulation is the systematic arrangement of the statistical data in columns or rows. It involves the orderly and systematic presentation of numerical data in a form designed to explain the problem under consideration. Tabulation helps in drawing the inference from the statistical figures.

Tabulation prepares the ground for analysis and interpretation. Therefore a suitable method must be decided carefully taking into account the scope and objects of the investigation, because it is very important part of the statistical methods.

Types of Tabulation

In general, the tabulation is classified in two parts, that is a simple tabulation, and a complex tabulation.

Simple tabulation, gives information regarding one or more independent questions. Complex tabulation gives information regarding two mutually dependent questions.

Two-Way Table

These types of table give information regarding two mutually dependent questions. For example, question is, how many millions of the persons are in the Divisions; the One-Way Table will give the answer. But if we want to know that in the population number, who are in the majority, male, or female. The Two-Way Tables will answer the question by giving the column for female and male. Thus the table showing the real picture of divisions sex wise is as under:

Three-Way Table

Three-Way Table gives information regarding three mutually dependent and inter-related questions.

For example, from one-way table, we get information about population, and from two-way table, we get information about the number of male and female available in various divisions. Now we can extend the same table to a three way table, by putting a question, “How many male and female are literate?” Thus the collected statistical data will show the following, three mutually dependent and inter-related questions:

  1. Population in various division.
  2. Their sex-wise distribution.
  3. Their position of literacy.

Presentation of Data

Presentation of data is of utter importance nowadays. Afterall everything that’s pleasing to our eyes never fails to grab our attention. Presentation of data refers to an exhibition or putting up data in an attractive and useful manner such that it can be easily interpreted. The three main forms of presentation of data are:

  1. Textual presentation
  2. Data tables
  3. Diagrammatic presentation

Textual Presentation

The discussion about the presentation of data starts off with it’s most raw and vague form which is the textual presentation. In such form of presentation, data is simply mentioned as mere text, that is generally in a paragraph. This is commonly used when the data is not very large.

This kind of representation is useful when we are looking to supplement qualitative statements with some data. For this purpose, the data should not be voluminously represented in tables or diagrams. It just has to be a statement that serves as a fitting evidence to our qualitative evidence and helps the reader to get an idea of the scale of a phenomenon.

For example, “the 2002 earthquake proved to be a mass murderer of humans. As many as 10,000 citizens have been reported dead”. The textual representation of data simply requires some intensive reading. This is because the quantitative statement just serves as an evidence of the qualitative statements and one has to go through the entire text before concluding anything.

Further, if the data under consideration is large then the text matter increases substantially. As a result, the reading process becomes more intensive, time-consuming and cumbersome.

Data Tables or Tabular Presentation

A table facilitates representation of even large amounts of data in an attractive, easy to read and organized manner. The data is organized in rows and columns. This is one of the most widely used forms of presentation of data since data tables are easy to construct and read.

Components of Data Tables

  • Table Number: Each table should have a specific table number for ease of access and locating. This number can be readily mentioned anywhere which serves as a reference and leads us directly to the data mentioned in that particular table.
  • Title: A table must contain a title that clearly tells the readers about the data it contains, time period of study, place of study and the nature of classification of data.
  • Headnotes: A headnote further aids in the purpose of a title and displays more information about the table. Generally, headnotes present the units of data in brackets at the end of a table title.
  • Stubs: These are titles of the rows in a table. Thus a stub display information about the data contained in a particular row.
  • Caption: A caption is the title of a column in the data table. In fact, it is a counterpart if a stub and indicates the information contained in a column.
  • Body or field: The body of a table is the content of a table in its entirety. Each item in a body is known as a ‘cell’.
  • Footnotes: Footnotes are rarely used. In effect, they supplement the title of a table if required.
  • Source: When using data obtained from a secondary source, this source has to be mentioned below the footnote.

Construction of Data Tables

There are many ways for construction of a good table. However, some basic ideas are:

  • The title should be in accordance with the objective of study: The title of a table should provide a quick insight into the table.
  • Comparison: If there might arise a need to compare any two rows or columns then these might be kept close to each other.
  • Alternative location of stubs: If the rows in a data table are lengthy, then the stubs can be placed on the right-hand side of the table.
  • Headings: Headings should be written in a singular form. For example, ‘good’ must be used instead of ‘goods’.
  • Footnote: A footnote should be given only if needed.
  • Size of columns: Size of columns must be uniform and symmetrical.
  • Use of abbreviations: Headings and sub-headings should be free of abbreviations.
  • Units:There should be a clear specification of units above the columns.

The Advantages of Tabular Presentation

  • Ease of representation: A large amount of data can be easily confined in a data table. Evidently, it is the simplest form of data presentation.
  • Ease of analysis: Data tables are frequently used for statistical analysis like calculation of central tendency, dispersion etc.
  • Helps in comparison: In a data table, the rows and columns which are required to be compared can be placed next to each other. To point out, this facilitates comparison as it becomes easy to compare each value.
  • Economical: Construction of a data table is fairly easy and presents the data in a manner which is really easy on the eyes of a reader. Moreover, it saves time as well as space.

Classification of Data and Tabular Presentation

Qualitative Classification

In this classification, data in a table is classified on the basis of qualitative attributes. In other words, if the data contained attributes that cannot be quantified like rural-urban, boys-girls etc. it can be identified as a qualitative classification of data.

Sex Urban Rural
Boys 200 390
Girls 167 100

Quantitative Classification

In quantitative classification, data is classified on basis of quantitative attributes.

Marks No. of Students
0-50 29
51-100 64

Temporal Classification

Here data is classified according to time. Thus when data is mentioned with respect to different time frames, we term such a classification as temporal.

Year Sales
2016 10,000
2017 12,500

Spatial Classification

When data is classified according to a location, it becomes a spatial classification.

Country No. of Teachers
India 139,000
Russia 43,000

Advantages of Tabulation

  1. The large mass of confusing data is easily reduced to reasonable form that is understandable to kind.
  2. The data once arranged in a suitable form, gives the condition of the situation at a glance, or gives a bird eye view.
  3. From the table it is easy to draw some reasonable conclusion or inferences.
  4. Tables gave grounds for analysis of the data.
  5. Errors, and omission if any are always detected in tabulation.

Therefore the importance of a carefully drawn table is vital for the preparation of data for analysis and interpretation.

Introduction, Meaning, Definitions, Features, Objectives, Functions, Importance and Limitations of Statistics

indiafreenotesby indiafreenotes0

Statistics is a branch of mathematics focused on collecting, organizing, analyzing, interpreting, and presenting data. It provides tools for understanding patterns, trends, and relationships within datasets. Key concepts include descriptive statistics, which summarize data using measures like mean, median, and standard deviation, and inferential statistics, which draw conclusions about a population based on sample data. Techniques such as probability theory, hypothesis testing, regression analysis, and variance analysis are central to statistical methods. Statistics are widely applied in business, science, and social sciences to make informed decisions, forecast trends, and validate research findings. It bridges raw data and actionable insights.

Definitions of Statistics:

A.L. Bowley defines, “Statistics may be called the science of counting”. At another place he defines, “Statistics may be called the science of averages”. Both these definitions are narrow and throw light only on one aspect of Statistics.

According to King, “The science of statistics is the method of judging collective, natural or social, phenomenon from the results obtained from the analysis or enumeration or collection of estimates”.

Horace Secrist has given an exhaustive definition of the term satistics in the plural sense. According to him:

“By statistics we mean aggregates of facts affected to a marked extent by a multiplicity of causes numerically expressed, enumerated or estimated according to reasonable standards of accuracy collected in a systematic manner for a pre-determined purpose and placed in relation to each other”.

Features of Statistics:

  • Quantitative Nature

Statistics deals with numerical data. It focuses on collecting, organizing, and analyzing numerical information to derive meaningful insights. Qualitative data is also analyzed by converting it into quantifiable terms, such as percentages or frequencies, to facilitate statistical analysis.

  • Aggregates of Facts

Statistics emphasize collective data rather than individual values. A single data point is insufficient for analysis; meaningful conclusions require a dataset with multiple observations to identify patterns or trends.

  • Multivariate Analysis

Statistics consider multiple variables simultaneously. This feature allows it to study relationships, correlations, and interactions between various factors, providing a holistic view of the phenomenon under study.

  • Precision and Accuracy

Statistics aim to present precise and accurate findings. Mathematical formulas, probabilistic models, and inferential techniques ensure reliability and reduce the impact of random errors or biases.

  • Inductive Reasoning

Statistics employs inductive reasoning to generalize findings from a sample to a broader population. By analyzing sample data, statistics infer conclusions that can predict or explain population behavior. This feature is particularly crucial in fields like market research and public health.

Statistics provide a scientific basis for making informed decisions. By quantifying uncertainty and evaluating risks, statistical tools guide individuals and organizations in choosing the best course of action, whether it involves investments, policy-making, or operational improvements.

  • Facilitating Hypothesis Testing

Statistics validate or refute hypotheses through structured experiments and observations. Techniques like hypothesis testing, significance testing, and analysis of variance (ANOVA) ensure conclusions are based on empirical evidence rather than assumptions or biases.

Functions of Statistics:

  • Collection of Data

The first function of statistics is to gather reliable and relevant data systematically. This involves designing surveys, experiments, and observational studies to ensure accuracy and comprehensiveness. Proper data collection is critical for effective analysis and decision-making.

  • Data Organization and Presentation

Statistics organizes raw data into structured and understandable formats. It uses tools such as tables, charts, graphs, and diagrams to present data clearly. This function transforms complex datasets into visual representations, making it easier to comprehend and analyze.

  • Summarization of Data

Condensing large datasets into concise measures is a vital statistical function. Descriptive statistics, such as averages (mean, median, mode) and measures of dispersion (range, variance, standard deviation), summarize data and highlight key patterns or trends.

  • Analysis of Relationships

Statistics analyze relationships between variables to uncover associations, correlations, and causations. Techniques like correlation analysis, regression models, and cross-tabulations help understand how variables influence one another, supporting in-depth insights.

  • Predictive Analysis

Statistics enable forecasting future outcomes based on historical data. Predictive models, probability distributions, and time series analysis allow organizations to anticipate trends, prepare for uncertainties, and optimize strategies.

  • Decision-Making Support

One of the most practical functions of statistics is guiding decision-making processes. Statistical tools quantify uncertainty and evaluate risks, helping individuals and organizations choose the most effective solutions in areas like business, healthcare, and governance.

Importance of Statistics:

  • Decision-Making Tool

Statistics is essential for making informed decisions in business, government, healthcare, and personal life. It helps evaluate alternatives, quantify risks, and choose the best course of action. For instance, businesses use statistical models to optimize operations, while governments rely on it for policy-making.

Limitations of Statistics:

  • Does Not Deal with Qualitative Data

Statistics focuses primarily on numerical data and struggles with subjective or qualitative information, such as emotions, opinions, or behaviors. Although qualitative data can sometimes be quantified, the essence or context of such data may be lost in the process.

  • Prone to Misinterpretation

Statistical results can be easily misinterpreted if the underlying methods, data collection, or analysis are flawed. Misuse of statistical tools, intentional or otherwise, can lead to misleading conclusions, making it essential to use statistics with caution and expertise.

  • Requires a Large Sample Size

Statistics often require a sufficiently large dataset for reliable analysis. Small or biased samples can lead to inaccurate results, reducing the validity and reliability of conclusions drawn from such data.

  • Cannot Establish Causation

Statistics can identify correlations or associations between variables but cannot establish causation. For example, a statistical analysis might show that ice cream sales and drowning incidents are related, but it cannot confirm that one causes the other without further investigation.

  • Depends on Data Quality

Statistics rely heavily on the accuracy and relevance of data. If the data collected is incomplete, inaccurate, or biased, the resulting statistical analysis will also be flawed, leading to unreliable conclusions.

  • Does Not Account for Changing Contexts

Statistical findings are often based on historical data and may not account for changes in external factors, such as economic shifts, technological advancements, or evolving societal norms. This limitation can reduce the applicability of statistical models over time.

  • Lacks Emotional or Ethical Context

Statistics deal with facts and figures, often ignoring human values, emotions, and ethical considerations. For instance, a purely statistical analysis might prioritize cost savings over employee welfare or customer satisfaction.

Introduction to Business Communication, Types, Purpose

indiafreenotesby indiafreenotes0

Business Communication refers to the exchange of information, ideas, and messages within and outside an organization to achieve its objectives. It involves verbal, non-verbal, and written forms of communication to convey messages effectively among employees, management, and external stakeholders like customers, suppliers, and investors. Clear and efficient business communication enhances collaboration, decision-making, and operational efficiency. It includes tools such as reports, emails, presentations, and meetings. Effective communication skills are essential for building relationships, resolving conflicts, and ensuring organizational success. In a globalized business environment, understanding cultural nuances and leveraging technology are critical to improving communication processes.

Types of Business Communication:

Business communication can be classified into various types based on its purpose, direction, and methods.

1. Internal Communication

Internal communication occurs within the organization and is crucial for ensuring that employees and management are on the same page. It can be further divided into:

  • Upward Communication: Information flows from employees to managers or higher authorities. For example, feedback, reports, and suggestions.
  • Downward Communication: Information flows from management to employees, such as instructions, policies, and announcements.
  • Lateral Communication: Communication among employees or departments at the same organizational level. For instance, team discussions or inter-departmental collaboration.

2. External Communication

External communication involves interactions with individuals or entities outside the organization, such as customers, suppliers, investors, or regulators. It aims to build relationships, share information, or market products and services. Examples include press releases, advertisements, and client negotiations.

3. Verbal Communication

Verbal communication uses spoken words for the exchange of information. It is quick and allows for immediate feedback. Examples are:

  • Face-to-Face Communication: Meetings, interviews, or presentations.
  • Telephonic Communication: Calls or virtual meetings using tools like Zoom or Teams.

4. Non-Verbal Communication

Non-verbal communication includes gestures, facial expressions, posture, and tone of voice that complement or reinforce the message. For example, a firm handshake during a business meeting conveys confidence, while positive body language enhances understanding.

5. Written Communication

Written communication involves the use of written or printed words. It is used for record-keeping, formal communication, or when accuracy is essential. Examples include emails, reports, memos, proposals, and business letters. Written communication is reliable and provides a reference for future use.

6. Formal Communication

Formal communication follows predefined channels and structures, such as official memos, policies, and reports. It ensures clarity, professionalism, and adherence to organizational protocols.

7. Informal Communication

Informal communication, or the “grapevine,” occurs without formal structures. It includes casual conversations among colleagues, which can help build relationships but might also lead to misinformation if unchecked.

8. Digital Communication

In the digital era, communication increasingly relies on technology. Tools like emails, instant messaging (e.g., Slack), social media, and video conferencing are integral to modern business operations.

Purpose of Communication in Business:

  • Information Sharing

Communication serves as the foundation for sharing essential information within a business. Employees, managers, and stakeholders exchange data, updates, and reports to ensure that everyone is aligned with organizational goals. For instance, a manager communicates a project timeline to a team to keep them informed about deadlines and deliverables.

  • Decision-Making

Effective communication facilitates sound decision-making by providing relevant information and insights. Managers rely on clear communication to gather feedback, analyze options, and make informed choices. For example, data-driven reports and collaborative discussions help leaders decide on resource allocation, market strategies, or product launches.

Basic Forms of Communication

indiafreenotesby indiafreenotes0

Forms of Communication refer to the various ways in which information, ideas, and messages are exchanged between individuals or groups. The primary forms include verbal communication, which uses spoken or written words; non-verbal communication, expressed through body language, gestures, and facial expressions; and visual communication, which employs images, charts, and graphs. These forms can occur in person, over digital platforms, or via traditional media. Effective use of these forms enhances understanding, collaboration, and relationship-building in personal and professional settings.

Forms of Communication on the Basic of Expression

The method or way of conveying and exchanging one’s ideas, opinions and emotions is known as communication medium. Keeping in view the objects and utility of the message, different modes are used in conveying the message.

  1. Verbal Communication

Communication through spoken and written words is known as verbal communication. In other words, When message is transmitted by sender to receiver with the help of words spoken or written, it is called as verbal communication. The process of communication involves the use of common set of symbols between the sender and the recipient. Words are most accurate and powerful set of symbols, Therefore most of the communication take place through words. Verbal communica5ion can be to of two types.

(i)  Oral Communication: When communication is done by words spoken, it is called oral communication. In this type of communication, exchange of opinions is done through face to face communication or through some mechanical device. Oral communication takes place in different ways such as personal talks, speeches, interviews, seminars, telephone talks etc. In the oral communication , receiver also comes to know the body language of the sender. If the receiver cannot understand the messages, he can also get clarified at once form the sender. Oral communication is speedy, saves time , provide immediate feedback and provides better under- standing by removing doubts and fears.

(ii) Written Communication:  Exchange of messages in written or printed form is known as written communication . This type of communication takes place in different ways such us letters, memos, reports, notices, circulars, magazines etc. It need utmost care while preparing the written message. The choice of words should be done carefully in written communication and the words should be such so as to convey a specific meaning. In the modern age, need and importance of written communication is increasing day by day.

  1. Non Verbal Communication

Any communications without the use of words is known as non-verbal communication. It is a process of communication in which transmission of messages is done through facial expressions, body posture, eye contact, appearance, silence it. Studies reveal that more than 65% of human communication is done through non-verbal clues. It makes verbal communication complete and more effective. By using non-verbal form of communication, a person can express his feelings to other quickly and economically. Raising eyebrows, lines on the forehead, raising hands, shaking the head, smiling, clapping etc. communicate much more than words. While communicating it should be remembered that the way of speaking is as important as what you speak. Infact one expert contends that only 7% of as impact of our face to face  communication comes from the words we spoke, the other 93% comes form our vocal intonation, facial expressions, posture and appearance.

(i) Body language or kinesics: The study of message conveyed by body movements is known as body language. Just as language uses symbols to convey message, our body movements convey messages such as rubbing the nose for feeling tense, putting the hand on forehead for distress, raising hand by a traffic policeman to stop the traffic etc. are the examples of body language. Body language helps to complete the verbal communication. Man may play with words but his body movements speak the truth.

(ii)  Sing Language: It is a method in which different signs, pictures, signals, colours are used to convey the message. Signs can be of two types- audio signs and visual signs.

Audio sign include buzzers, electric bells, sirens, hooters etc. which produce different sounds to convey the messages. For example hooting of siren in a factory immediately makes the workers active. Visual signs such as posters, cartoons, pictures, colours etc. are used to convey message for general information and education. People all over the worlds recognize what the traffic lights red, yellow and green. The symbols of two crossed bones below a skull means danger and a crossed cigarette means no smoking.

(iii)  Para language:  In the Para language tone of voice, pitch, rhythm, volume, break in sentences etc. are used to convey the message. In Para language, we examine the sound of someone speech. Voice tells us so much about the speaker sex, background, education and temperament. Clearer the voice is more effective will be the communication. In the same way, stress on different words changes the meaning of message every time. For example, in a sentence ‘you may go’ if stress is laid on the word go then it shows anger. With the help of para language mental situation of a person can be studied easily.

On the Basic of Direction

On the basic of direction of flow of communication, is can be classified as under:

  1. Vertical communication

Every organization has a hierarchical line of authority along which runs a communication channel used for transmitting all written and oral messages. When message flow from higher authorities to subordinates or from subordinates to higher authorities along with different levels of organization structure is known as vertical communication. In this type of communication, messages and direction passes along the scalar chain for example, board of director( highest authority of the organization ) passes his orders and direction to the managing director and managing director passes on necessary and relevant information to departmental managers, who in turn, issue instructions to supervisors. Vertical communication can be of two forms :

(i) Downward communication: When message is transmitted from higher authorities to subordinates and lover class of employees, it is known as downward communication. Through this managers provide information to his subordinates regarding the policies, plans and programmers of the enterprise. Orders, bulletin, job-sheets, manuals, guidelines are its main examples. It can be shown as follows:

(ii) Upward Communication:  When message is transmitted from subordinates to higher authorities then it is known as upward communication. This communication system is usually used to communicate the problems grievances, suggestions and reactions of workers to managers. For the success of this system, it is necessary to have open door policy, management workers meetings, participation attitude in the business etc. This system increases the morale and productivity of workers.

  1. Lateral or Horizontal Communication

When communication takes place between two or more persons who are linked to each other by equal status or equality of relationship. The meeting of general managers of various units of the company, communication between territorial sales managers are the examples of horizontal communication. The main objective of this communication is to establish co-ordination in the business so that works and decisions are fulfilled quickly and efficiently.

  1. Diagonal Communication

The transfer of information among people who are neither in the same department nor on the same level of organizational hierarchy is called diagonal communication. In other words it refers to the interchange of messages among the persons located at different levels of hierarchy and outside the direct chain of command. When the assistant Finance manager communicates with the accounts clerk directly is an example of diagonal communication. Diagonal flow of communication short- circuits the rigid chain of command. Informal meeting. Lunch hour meeting, conference project organization meeting etc. is the main media of this type of communication.

On the Basic of Organizational Structure

Communication on the basic of organizational structure may be classified into two categories formal and informal.

  1. Formal Communication

Formal communication is closely associated with a formal organizational structure. Under this system, the message flows according to a fixed and prescribed way. It follows the pre- decided procedures, rules and regulation for the transmission of messages. Formal channel of communication recognizes superior and subordinate positions and relationship. This system ensures flow of information in a planned route smoothly, accurately and timely. Infact, this communication takes place between two positions and not between persons.

  1. Informal Communication

It is not a planned or deliberately created channel of communication. It is free from all formalities. No formal organization chart is followed to convey the messages. It is based on the informal relations of the two persons. Body language is also used in informal communication like to show anger, to smile, remain silent etc. it is most flexible and speedy channel of communication. But his type of communication is difficult to control and often misunderstanding .

Management Notes

Process of Communication

indiafreenotesby indiafreenotes0

The process of communication involves the systematic exchange of information between a sender and a receiver. It begins with the sender encoding a message and transmitting it through a chosen medium (e.g., verbal, written, or digital). The receiver decodes the message, interprets its meaning, and provides feedback to complete the process. Effective communication relies on clarity, the right medium, and mutual understanding while minimizing barriers like noise, misinterpretation, or distractions that can disrupt the flow of information.

Communication Process:

The communication is a dynamic process that begins with the conceptualizing of ideas by the sender who then transmits the message through a channel to the receiver, who in turn gives the feedback in the form of some message or signal within the given time frame.

  1. Sender

The sender is the source of the message that initiates the communication. The sender has a message or purpose of communicating to one or more people. A manager in an organization has to communicate information about the tasks to be achieved or a production deadline to be met by his subordinate employees. Without a reason, purpose, or desire, the sender has no information/message to send.

  1. Encoding

In the next stage, encoding takes place when the sender translates the information or message into some words, signs or symbols. Without encoding the information cannot be transferred from one person to another. In encoding the message, the sender has to choose those words, symbols or gestures that he believes to have the same meaning for the receiver. While doing so, the sender has to keep the level of the receiver in mind and accordingly communicate with him in the way the receiver understands it.

The message may be in any form that can be understood by the receiver. Speech is heard; words are read; gestures are seen or felt and symbols are interpreted. For example, there are several communications we make with a wave of the hand or with a nod of the head, a pat on the back, blinking of eyes.

  1. Message

Once the encoding is finished, the sender gets the message that he intends to convey. The message can be written, oral, symbolic or non-verbal such as body gestures, silence, sighs, sounds, etc. or any other signal that triggers the response of a receiver.

Message is the idea or information that the sender wants to convey. He may convey it verbally (by writing or speaking) or non-verbally (through gestures or body language). Whatever the form, the message should be clearly formed so that the objective is accomplished.

  1. Channel

The channel is the medium used for transmission of information or message from sender to receiver. There are various media like telephone, mail through post, internet, radio, TV, press etc. For communication to be effective and efficient, the channel must be appropriate for the message. A phone conversation is not a suitable channel for transmitting a complex engineering diagram.

An express mail may be more appropriate. The needs and requirements of the receiver must also be considered in selecting a channel. If the receiver is illiterate, sending the message through postal mail is not relevant. Similarly, you cannot select the medium of telephone, if the receiver does not have a telephone with him. Therefore, in choosing the appropriate channel, the manager must decide whether feedback is important or not.

  1. Receiver

The receiver is the person who senses or perceives or receives the sender’s message. There may be just one receiver or a large number of receivers. The message must be prepared with the receiver’s background in mind. An engineer in a software organization should avoid using technical terms in communicating with his family members. It should be recognized that if the message does not reach a receiver, no communication takes place. Even, when the message reaches the receiver, if he cannot understand it, again there is no communication.

  1. Decoding

Decoding is the process through which the receiver interprets the message and translates it into meaningful information. It may be remembered that decoding is affected by the receiver’s past experience, personal assessments of the symbols and gestures, expectations, and mutuality of meaning with the sender.

  1. Noise

It represents the disturbing factor in the process of communication. It interferes with effective communication and reduces clarity of the message. The message may be interpreted differently than intended by the sender. Conversing near a machine making sounds, disturbance in telephone line, physical ailment or mental distress of sender or receiver are the common causes of noise that obstruct the quality of message transmitted from sender to the receiver.

  1. Feedback

Feedback is receiver’s response to the sender’s message. The receiver communicates reaction to the sender through words, symbols or gestures. It is the reversal of communication process where receiver becomes the sender and sender becomes the receiver. Unless the receiver responds to the message, communication process is incomplete. Feedback helps the sender transform his message, if needed. It also allows the receiver to clear doubts on the message, ask questions to build his confidence and enables the sender to know efficiency of the message. Feedback of information makes the communication process complete.

In face-to-face communication, sender can immediately receive the feedback. Written communication, on the other hand, takes longer for the sender to receive feedback on the message.

Feedback plays important role in two-way communication. In one-way communication, sender communicates with the receiver without getting any feedback but in two-way communication, the receiver provides feedback to the sender. Though one-way communication takes less time and is more orderly (it avoids noise and chaos), feedback in two-way communication makes it more accurate and precise.
