Cumulative Frequency Graphs

To plot cumulative frequency graphs students are taught to find the cumulative frequency from grouped data tables, choose suitable axes and how to plot the curve.  As learning progresses students learn how to draw the median average and interquartile range from the graph and what they represent about the data.
Differentiated Learning Objectives
  • All students should be able to plot a cumulative frequency graph from a grouped data table.
  • Most students should be able to plot and interpret the median and IQR from a cumulative frequency graph.
  • Some students should be able to plot and interpret a cumulative frequency to compare multiple data sets.
