To plot histograms at GCSE students are taught to find the frequency density from grouped data with unequal class widths.
There are worksheets provided in the additional resources section so both students and their teacher can plot the histograms together.
Differentiated Learning Objectives
- All students should understand the need for histograms with unequal class width and calculate the frequency density.
- Most students should understanding the need for and be able to plot histograms with unequal class widths.
- Some students should be able to compare data sets by plotting and interpreting histograms with unequal class widths.
