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

I think that the Pie Chart is not and appropriate graph to represent this information.

Why do you think it's not appropriate?

The pie chart gives it to the nearest whole number does it is not accurate compared to the other graphs

What makes you think the 3 remaining graphs are appropriate?

The others are appropriate as each of them can show clearly the exact amount there is to the audience, also all 3 have different uses.

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?
