- Work on frequency tables, cumulative frequency tables and graphs, box (and whisker) plots and time series is included in APT’s set of PowerPoints on ‘Analysing Data’.
- Work on conversion graphs is included in APT’s set of PowerPoints on ‘Graphs’.
- Work on distance-time graphs are included in APT’s set of PowerPoints on ‘Geometry’, which includes work on speed.
- There are also additional PowerPoints available that cover the additional GCSE Statistics parts of this module of statistical work – covering sampling in more depth, comparative pie charts, population pyramids and choropleths.
