Data Handling: Choice of Graphs by Walter Koh


  • Can you identify the one that is not appropriate?
  • Why do you think it's not appropriate?
  • What makes you think the 3 remaining graphs are appropriate?

The pie chart is not too appropriate, as it does not effectively show information and it only shows the size of the angle the information will be when put in the pie chart. 
I think the other 3 remaining graphs are appropriate because they effectively show accurate information. Also, they are easy to read. 
The graph I find inappropriate:

  1. Pie chart shows the 'proportion', which tells us how often each type of weather occurs by the size of each pie. So, it's still appropriate.

    There are situations when we do not require the exact figures, but just need to tell the 'size' of occurrence at a glance. That's where pie chart is useful.

    So, which graph is inappropriate, and why?
