11+ Maths: Mean, Median, Mode and Range Practice
21 October 2026
Understanding averages for 11+ maths
Mean, median, mode and range are key topics in 11+ maths. They help children describe and compare sets of numbers. Knowing how to find each one gives your child confidence with data questions.
What each term means
Mean is the average. Add all the numbers, then divide by how many numbers there are.
Median is the middle value when the numbers are put in order from smallest to largest.
Mode is the number that appears most often in the list.
Range shows how spread out the numbers are. Subtract the smallest number from the largest.
Worked example
Let's use these numbers: 3, 7, 7, 10, 12
Step 1: Mean
Add all the numbers: 3 + 7 + 7 + 10 + 12 = 39
Divide by how many numbers: 39 ÷ 5 = 7.8
Step 2: Median Put the numbers in order: 3, 7, 7, 10, 12 The middle value is 7
Step 3: Mode The number that appears most is 7
Step 4: Range Largest number - smallest number: 12 - 3 = 9
So, for this set: Mean = 7.8 Median = 7 Mode = 7 Range = 9
Why practice matters
Practising these skills helps your child spot patterns, check their answers, and avoid common mistakes in 11+ maths questions.
Key insight: Regular practice with mean, median, mode and range makes it easier for children to recognise which method to use and builds confidence for the 11+ exam.
