In this lesson
In this video you'll learn about mean, median, mode and range for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to calculate the mean, median, mode and range for a list of individual data values, knowing which average serves which purpose.
What it covers
- 1:31 The mean shares the total out evenly
- 5:28 Your turn
- 6:57 Last thing, and it is not a calculation: the names
- 7:56 What's next

On the specification
| Board | Spec | Statement |
|---|---|---|
| Cambridge IGCSE 0580 | C9.3 | Calculate the mean, median, mode and range for individual data and distinguish between the purposes for which these are used. |
| Cambridge IGCSE 0580 | E9.3 | Calculate the mean, median, mode, quartiles, range and interquartile range for individual data and distinguish between the purposes for which these are used. |
| Edexcel IGCSE 4MA1 | F6.2A | Understand the concept of average |
| Edexcel IGCSE 4MA1 | F6.2B | Calculate the mean, median, mode and range for a discrete data set |
| 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. |
| 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 | FS4 | 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 outlier) |
| 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) |
For teachers
This GCSE Maths lesson teaches mean, median, mode and range. By the end, students should be able to calculate the mean, median, mode and range for a list of individual data values, knowing which average serves which purpose. It works through two worked examples and the mistakes examiners report.
