Constructing and reading box plots
MA32-05
This lesson is coming soon.
In this lesson
Construct a box plot from the minimum, quartiles and maximum, and read the five summary values off a given box plot.
What it covers
- Construct a box plot on a labelled scale from a given five-number summary (min, LQ, median, UQ, max)
- Read the five summary values off a given box plot
- State what proportion of the data each section of the box plot represents (25% per section)

On the specification
| Board | Spec | Statement |
|---|---|---|
| AQA GCSE 8300 | S4 | • including box plots |
| Edexcel GCSE 1MA1 | S4 | interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: • appropriate graphical representation involving discrete, continuous and grouped data • appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers) |
| Eduqas GCSE C300 | HS5 | Interpret, analyse and compare the distributions of data sets from univariate empirical distributions through: appropriate graphical representation involving discrete, continuous and grouped data, including box plots; appropriate measures of central tendency (median, mean, mode and modal class) and spread (range, including consideration of outliers, quartiles and inter-quartile range) |
| OCR GCSE J560 | 12.03a | Calculate the mean, mode, median and range for ungrouped data. Find the modal class, and calculate estimates of the range, mean and median for grouped data, and understand why they are estimates. Describe a population using statistics. Make simple comparisons. Compare data sets using `like for like' summary values. Understand the advantages and disadvantages of summary values. |
For teachers
This GCSE Maths lesson teaches constructing and reading box plots. By the end, students should be able to construct a box plot from the minimum, quartiles and maximum, and read the five summary values off a given box plot. It works through two worked examples and the mistakes examiners report.
