Perform statistical operations by using the COUNTIF function

Use COUNTIF, one of the statistical functions, to count the number of cells that meet a criterion; for example, to count the number of times a particular city appears in a customer list.

In its simplest form, COUNTIF says:

=COUNTIF(Where do you want to look?, What do you want to look for?)

For example:

• =COUNTIF(A2:A5,”London”)
• =COUNTIF(A2:A5,A4)

To use these examples in Excel, copy the data in the table below, and paste it in cell A1 of a new worksheet.
