eLearning Lesson 1 Task 1: Choice of Graphs by Sandy Khoo (8)

  • 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?
    • It is not appropriate as the information are rounded up,so it may not be very accurate. It is also quite troublesome to read as we still have to refer back to the legend.
    • What makes you think the 3 remaining graphs are appropriate?
    • The other graphs are quite accurate and we can see the information at a glance.

  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?
