Problem: You have a large dataset, as shown in Fig. 562. You want to count the number of records that meet a certain criteria. What function should you use?
Note: Click any image below to see a larger view of that figure.
Strategy: Use the COUNTIF function. This function requires two arguments. The first is a range of cells that you want to test. The second is a test. To count the records where the gender is “M”, use =COUNTIF(B2: B57, “M”), as shown in Fig. 563.
Note that the second argument of “M” indicates tells Excel to count records that are equal to M. Since this function is not case sensitive, the function will count cells with M or m.
If you want to count the records where the age is a specific number, as shown in Fig. 564, then you can write the formula either with or without quotes around the number:
The criteria can look for items that are below or above a certain number:
Summary: To count how many cells contain certain criteria, use the COUNTIF function by entering the two criteria it needs, which cells to count, and what to count.
Functions Discussed: =COUNTIF()
