You can use the following formula to count the number of occurrences by group in an Excel spreadsheet:
The following example shows how to use this formula in practice.
Example: Count by Group in Excel
Suppose we have the following dataset that shows the total points scored by 15 different basketball players:
Now suppose we’d like to count the number of players, grouped by team.
To do so, we can use the =UNIQUE() function to first create a list of the unique teams. We’ll type the following formula into cell F2:
Once we press enter, a list of unique team names will be displayed:
Next, we can use the =COUNTIF() function to find the count of players on each team.
We’ll type in the following formula into cell G2:
We’ll then copy and paste this formula into the remaining cells in column G:
Column F displays each of the unique teams and column G displays the count of players on each team.
