![]() Then you graph all the points (X, Y) corresponding to the classes and the cumulative frequencies. : The classes go on the X-axis, and the associated cumulative frequencies go on the Y-axis. : You need to construct the cumulative frequency for each class, by adding all the frequencies up to a given class. ![]() : You need to have the classes and their corresponding frequencies, where the classes are in ascending order. There are several steps, but it is essentially the same procedure as the one followed to Using a cumulative polygon is a way of assessing which how the frequencies of the classes stack up in relative terms, given you yet another dimension of distribution you are studying. Indeed, ogive is short name for a cumulative frequency polygon. The concept of give comes related with the concept of cumulative frequency graph. ![]()
