Ways of Presenting Data Part 2 - Higher Level Only
Subjects / Maths / Data Handling
In this title, we'll look at ways of presenting data using diagrams. We'll also look at measures of average and measures of spread. We use histograms when data is presented in groups that are not of equal size, so that the diagram in not misleading. We'll then explain cumulative frequency and look at how to draw cumulative frequency diagrams. We can use these diagrams to estimate the median value, as well as the lower and upper quartile values. The title then goes on to consider box plots. We'll look at how to draw this type of diagram, which highlights the minimum value, the lower quartile value, the median value, the upper quartile value and the maximum value in a sample. Finally, we'll discuss using moving averages, which allow us to analyse trends in data that has seasonal fluctuations.
