How do you find out the cumlative frequancy?

Answer 1

Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.
