Great question! Cumulative frequency is the total of the frequencies. This can be represented on a graph by plotting the upper boundaries of the groups! Hope that helps!

It's an addition of previous frequencies of the series of frequencies.

CF is calculated in frequency distribution table and is calculated such that the last frequency value in table is equal to the sum of all frequency values. Basically, by adding each frequency into sum of it predecessors.

A data set's cumulative frequency is used to calculate the number of observations that are above or below a certain value. There are two methods for calculating cumulative frequencies: utilising stem and leaf plots or straight from the data. A frequency distribution table is used to determine the cumulative frequency, which is the total of all the frequencies in the table. Since all frequencies have already been added to the previous total, the final number will always be equal to the sum of all observations.

The current frequency totaled with all the previous frequencies summed together. The last cumulative frequency taken should be the total frequency.
