eLearning Lesson 1 Task 1 Choice of Graphs by Gladys Foo (03)


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

Why do you think it's not appropriate?

The percentages of the information is rounded off to the nearest whole number, thus it is not appropriate



What makes you think the 3 remaining graphs are appropriate?


The data that is represented in the 3 remaining graphs are clearly shown, not estimated and can be easily understood.

  1. Your reasoning is based on accuracy in representating data (due to rounding off):

    If 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?
