I think the pie chart is not an appropriate choice.

Why do you think it's not appropriate?

The information is not accurate as they will round off the number into a whole number so it will fit in.

What makes you think the 3 remaining graphs are appropriate?

They do not round off the number.Therefore, they are appropriate.

Your reasoning is based on accuracy in representating data (due to rounding off):

ReplyDeleteIf the figures given, after calculating, result in exact figures (where no rounding off is necessary), would PIE graph still be appropriate then?

Points to ponder...

What kind of information does PIE chart usually provide?

Does each type of graph serve a different purpose or it doesn't matter?
