Statistics > (3) Communicate

Australian Curriculum Version 9 Says:

Identify statistically informed arguments presented in traditional and digital media; discuss and critique methods, data representations and conclusions.

What this means

Looking out for misleading graphs and statements. Questioning the source of secondary data (data collected by someone else).

  • The elaborations mention Pie Graphs

Misleading Graphs. Look for broken scales, non-linear axes, the scale of the images used in graphs e.g., pictographs and the incorrect use of graphs.

Tips

  • Pie graphs should only be used when the ‘whole’ is known. Slices of the pie represent categories.
  • Pie graphs require an understanding of angles within a circle (see AC9M5M04).
  • See AC9M4ST02 which involves analysing the effectiveness of different displays.
