You can use the following formula to count the number of occurrences by group in an Excel spreadsheet:

=COUNTIF(group_range, criteria)

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:

=UNIQUE(B2:B16)

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:

**=COUNTIF(B2:B16, F2)**

We’ll then copy and paste this formula into the remaining cells in column G:

That’s it!

Column F displays each of the unique teams and column G displays the count of players on each team.
