Geography isn't all about maps! During your KS3 geography lessons, you will have realised that you need to do some maths too. A lot of useful and interesting data is presented using tables and charts, for example, lists of the World's longest rivers or the capital cities in order of population. Tables and ordered lists are not necessarily the best way to present all data - it can often help to use some kind of chart. It is an important skill in geography to be able to look at data and decide what is the best way to present it.
If you have two sets of data that are linked, plotting them on a scatter graph and drawing a line of best fit will help to identify any relationship between them. You need to be able to recognise a positive or negative correlation and whether the relationship is linear or not. If you have a set of data that adds up to one hundred percent, then you could use a pie chart. When drawing any form of chart, use different colours to represent the different types of data.
