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 graph

Why do you think it's not appropriate?

It is not appropriate as the data in it are rounded off (as shown in the bottom right hand corner of the graph), and it is not that simple to interpret the data there.

What makes you think the 3 remaining graphs are appropriate?

They can accurately show data and the data in it is not rounded off and it is easier to interpret the data.

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?

You metnioned it's not simple to interpret... then make a guess, what kind of information does pie chart normally provide? (exact figure or... ?)

Points to ponder...

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