Help your students prepare for their Maths GCSE with this free histograms worksheet of 20 questions and answers
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 succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
