Cumulative frequency is the total of a frequency and all frequencies in a frequency distribution until a certain defined class interval. Learn more about the interesting concept of cumulative frequency, the types, plotting a graph, and solve a few examples.
Cumulative frequency graphs (or cumulative frequency diagrams) are useful when representing or analyzing a cumulative frequency distribution of large grouped data sets. Cumulative frequency graphs are called ogive graphs.
A cumulative frequency graph is like a cumulative frequency histogram, but uses line segments instead of bars. You can make a cumulative frequency graph from a cumulative frequency histogram by drawing line segments that connect the upper right corners of the histogram’s bars. The figure at the right shows a cumulative frequency graph
