In KS2 Maths, children learn about handling data. In Years Five and Six, they explore collecting, recording, and presenting data using graphs and charts. They also discover the concepts of range and averages—mean, median, and mode.
Handling data means using tables, charts, and diagrams. Have you heard of Carroll diagrams? They're named after Lewis Carroll, who wrote Alice's Adventures in Wonderland. Data also includes ranges and averages. Range is the difference between the highest and lowest frequencies. There are three types of averages: mean, median, and mode.
Test your knowledge with this fun quiz designed for 9-11 year olds and see how much you've learned about handling data and averages.

Mean is the third method of finding an average of a set of numbers or data

11 + 14 + 17 + 18 + 20 = 80
