Frequency table worksheet for Statistics
In Statistics a frequency table is often the first summary of survey data: build one from a raw list, add the frequencies for the total count, and keep running totals for cumulative frequency. The mean, median and mode all come from the same table without writing the data out.
Also taught in Pre-Algebra and Algebra 1, each at its own level and with its own examples.

How to do these
Pets: 0 (5), 1 (8), 2 (4), 3 (3). Find the cumulative frequency for each value, top to bottom.
- Start with the first count: 5.
- Add each new count to the running total: 5 + 8 = 13, 13 + 4 = 17, 17 + 3 = 20.
The answer is .
Where students go wrong
Dividing by the number of rows when finding the mean. Four rows whose frequencies add to 20 stand for 20 values, so the mean is the weighted total over 20, not over 4.
Also called frequency table, frequency tables, relative frequency or mean from a frequency table.
