The mots amount of what ever it is like 2 red marbles 2 green and 6 yellow what will you get yellow

Cumulative frequency is the sum total of the frequencies. For example if there are 5 students who scored above 80 and 5 students who scored above 70 but less than or equal to 80, the frequency in each score is 5 but the cumulative frequency of the students scoring more than 70 is 10 (5+5).

A Cumulative Frequency is like a measuring table

It is the amount of variables in a mathematical conundrum.
