Mean Median Mode Practice: Calm Support for 11+ Preparation

19 October 2026

Understanding the basics

Mean, median and mode are three ways to describe the centre of a set of numbers. For the 11+ Maths test, children are expected to know how to calculate each one and spot the differences between them.

Key insight: Practising these skills helps children tackle a wide range of data questions with more confidence.

How to practise mean

To find the mean (average), add up all the numbers in the set and divide by how many numbers there are. For example, with 6, 8, 10, and 12: (6 + 8 + 10 + 12) = 36. Then, 36 ÷ 4 = 9. Practise with different sets of numbers, including both small and larger values.

Working out the median

The median is the middle value when the numbers are put in order. If there is an even number of values, find the mean of the two middle numbers. For example, for 3, 7, 8, 12, 15, the median is 8. For 4, 8, 10, 12, the median is (8 + 10) ÷ 2 = 9.

Key insight: Encourage your child to always write the numbers in order before finding the median.

Finding the mode

The mode is the number that appears most often in a set. A set can have more than one mode, or no mode at all if all numbers are different. For example, in 2, 4, 4, 5, 7, the mode is 4. Practise by creating sets with one, two, or no modes to help your child recognise each case.

Tips for calm practice at home

Start with short, focused sessions. Use real-life examples, such as ages in your family or favourite numbers. Mix up the order. Sometimes ask for mean, sometimes median or mode. Encourage your child to explain their steps out loud, which helps spot mistakes and build understanding.

Key insight: Mistakes are part of learning. Review any errors together, and use them as a chance to reinforce the method. Not just the answer.
