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

Cumulative frequency graphs are to estimate the median and quartiles when data is grouped. Drawing a cumulative frequency curve: 1. Add an extra column to the table and find the cumulative frequency (i.e. running total) 2. Draw the axes — cumulative frequency is always on the vertical axis. Label your
results of the experiment are displayed in the following cumulative frequency graph. Use the graph to estimate the median reaction time. [1 mark]
