What is a cumulative frequency distribution? Simple definition, easy steps to make one. Instructions for TI calculators. Step by step videos. Learn how to construct and interpret a cumulative frequency distribution, a data representation that shows the accumulation of frequencies as you move through data intervals. See a step-by-step example, a table, and a graph of a cumulative frequency distribution for a set of scores. Calculating cumulative frequency gives you the sum (or running total) of all the frequencies up to a certain point in a data set. This measure is different from absolute frequency, which refers to the number of times a particular value appears in a data set. Cumulative Frequency: In statistics, cumulative frequency is defined as the sum of frequencies distributed across various class intervals. This involves organizing the data and their totals into a table where the frequencies are allocated according to each class interval.
