Data Handling: Choice of Graphs by Chin Ning


- I think the pie chart is not appropriate.
- The figures are rounded off, and the degrees means nothing compared to the others when they use the actual number instead of degrees.
- The numbers given on the other graphs are accurate, and easy to tell/see compared to the pie chart.

  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.

    As line graphs are used to present trends, it is therefore not appropriate in this situation as we are unable to tell the 'relationship' between each type of weather.
