Jia WenYou are bringing in the 'degree of accuracy' into the 'explanation'. What you say is right if we are reporting figures, in particular %, from the pie chart.On the other hand, try to interpret what does each slice of the pie represent. Would you be able to get some sensible interpretation, based on the set of data given?Do the same for the other charts provided. Does anyone of them give you some "Strange" interpretation?Clue: Look at the purpose of the each type of charts.Try again.Just a note: Keep in mind that each type of graph presents information differently and each has its own purpose. It may present information we are unable to obtain from other types of graphs.
