Data Handling: Choice of Graphs by Yadunand Prem

Can you identify the one that is not appropriate?
The pie chart is not appropriate.Why do you think it's not appropriate?
I don't think the piechart is appropriate as you could not help people understand it in a simple glance. Also, you need to do some calculations to understand the piechart properly.
What makes you think the 3 remaining graphs are appropriate
People can easily understand the piechart when they are trying to read it and it is also more accurate.

  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.

    You don't seem to have answer the last question on what makes you think the 3 remaining graphs are appropriate.
