A histogram is a frequency diagram used to display the frequency distribution of a grouped data set, often with unequal class widths. Histograms are primarily used to display continuous data and look very similar to bar charts, with a couple of key differences. Unlike on a bar graph, the bars on a histogram do not have gaps between them and the area of each bar is proportional to frequency. Frequency density is plotted on the y-axis.
When drawing histograms we first calculate the frequency density for each class interval by dividing frequency by class width. Then we need to draw a bar to represent each class interval, marking the height of the bar at the calculated frequency density.
Note that frequency densities can often have fraction or decimal values, so students must take care when selecting an appropriate scale for the frequency density axis.
Looking forward, students can then progress to additional Statistics worksheets, for example a pie chart worksheet, averages worksheet or line graphs worksheet.
For more teaching and learning support on Statistics our GCSE maths lessons provide step by step support for all GCSE maths concepts.
There will be students in your class who require individual attention to help them achieve their target GCSE maths grade. In a class of 30, it’s not always easy to provide.
