Cummulative Frequency Table Definition

Cummulative Frequency Table Definition: In statistics a method of grouping the frequencies of the value of some variable by adding the frequencies not greater than certain values of the variable.

In other words a cummulative frequency table is a statistical method that has a column called cumulative frequency which tally's up the values of the frequencies.

For example, if we take the pupils marks in a test and put them into a table. The cumulative frequency is the end column and is worked out by adding the previous frequencies.

The first cumulative frequency is just 5. The second number is 5+3 to make 8. The third cumulative frequency is 5+3+7 to give 15. And so on, this is all what cumulative frequency is...adding up the frequencies one by one.
