Among the 4 graphs (Line Graph, Bar Graphs, Pictograms, Pie Charts), identify ONE graph that is NOT an appropriate choice to represent the information?

The pie chart is not an appropriate graph.

Why do you think it's not appropriate?

It is not appropriate as the information on the pie chart is rounded off,may not be accurate,and represented in degrees and angles, so it is not appropriate to use it to demonstrate the weather forecast.

What makes you think the 3 remaining graphs are appropriate?

They are the exact data and is reliable as they come in whole numbers which are not rounded off.

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?
