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

Why do you think it's not appropriate?

I think it is not appropriate as it does not gives other the exact amount but only the angles of the pie charts thus they would need to calculate and find out the answer themselves and what if they could not calculate the answer,it would be a disaster.

What makes you think the 3 remaining graphs are appropriate?

I think that the remaining graphs are appropriate as the pictorial graphs show pictures thus people who is illiterate would be able to know the exact amount as it is clearly drawn with the data collected.For the bar graphs and the line graphs,i think it is appropriate as they show the exact amount using the data collected

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?
