Pie Graph

Why do you think it's not appropriate?

It is not appropriate because as it says there, the figures used in the pie chart are rounded off, so, the pie chart is not accurate thus, not appropriate.

What makes you think the 3 remaining graphs are appropriate?

The other graph's data is not rounded off, so they are accurate.

Based on your first reason, based 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?
