WebCumulative frequency graphs (or cumulative frequency diagrams) are useful when representing or analysing the distribution of large grouped data sets. They can also be used to find estimates for the median value, the … WebStep 1 : You need to have the classes and their corresponding frequencies, where the classes are in ascending order. Step 2 : You need to construct the cumulative frequency for each class, by adding all the frequencies up to a given class. Step 3 : The classes go on the X-axis, and the associated cumulative frequencies go on the Y-axis.
WebCumulative frequency is the running total of the frequencies. On a graph, it can be represented by a cumulative frequency polygon, where straight lines join up the points, or a cumulative frequency curve.
