Data Handling: Choice of Graphs by Taufiq Mohammed

  • 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?
1)I don't think the pie chart is appropriate as data handling are suppose to help people perceive data at a simple glance.But since there are angles involved in the piechart.Some calculations are needed to know how the weather was.For the other charts, the information was more accurate than this 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.

    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?
