The difference between COUNTIFS and COUNTIF is that the COUNTIF function counts cells that meet a single criterion, while the COUNTIFS function can count cells with one or multiple criteria.
Example: You are working with a dataset with the first name in column A, the last name in column B, and the salary in column C.
Formula 1: To count how many people with a salary of more than $70,000 and less than $85,000.
There are five people with an income between $70,000 and $85,000.
Formula 2: To count how many people with a salary between $70,000 and the average.
The average of column C (C2:C12) is $76,308.82, and there are two people having an income between $70,000 and the average.
Notes: The COUNTIFS Function
= COUNTIFS(Range 1, Criteria 1, Range 2, Criteria 2…)
– Range 1 is required, which is the first data range you need to count;
– Criteria 1 is required, which can be a number, a text string, an expression, or a cell reference;
– Range 2: is optional, which is the second data range that you need to count;
– Criteria 2: is optional, which can be a number, a text string, an expression, or a cell reference.
– You can add other range/criteria pairs but the maximum number of range/criteria pairs is 127.
Each range must have the same number of rows and columns as the first range criteria, otherwise, you will get the wrong result "#VALUE!".
