# Handling Data (Year 6)

In KS2 Maths children will spend a lot of time studying data handling. In Years Five and Six children should know about collecting and recording data and also presenting and interpreting it in a variety of graphs, charts and diagrams. In addition they will now be taught about range and the different forms of averages - mean, median and mode.

Handling data involves tables, charts and diagrams. You may have come across Carroll diagrams in your lessons which are used for grouping things in a yes/no fashion. Did you know these diagrams are named after Lewis Carroll - the author of Alice's Adventures in Wonderland? Data handling also involves ranges and averages. The range of data is the difference between the highest and lowest frequencies. There are three different types of average - mean, median and mode. Median is the middle frequency piece of data, mode is the one that appears most often and mean is worked out by adding all the frequencies together and dividing by the number of frequencies.

See how much you have learned about handling data and averages in this quiz aimed at 9-11 year olds.
