You can easily create a new type of statistics. The most relevant settings are Rows, Columns, Field, and Mode.

In most cases you will use the mode Count: the number of participants matching the row and the column field will be counted.
Alternatively, you can select a field over which the minimum/maximum/average/sum will be calculated.
If you want to restrict the participants considered for the statistics, enable Only Finishers or enter a General Filter.
