Using graphs and diagrams to show data
When you have your data, you may want to represent them graphically – for example, to show whether two variables are correlated (eg a scatter graph plotting duck egg length against duck egg width) or to show different proportions (eg a pie chart showing the prey items of a lion). Which chart or graph you use will depend on the type of data you have.
Common diagrams include bar charts, pie charts, line graphs, scatter graphs and histograms.
