elearning lesson 1 task 1: choice of graphs

  • Among the 4 graphs (Line Graph, Bar Graphs, Pictograms, Pie Charts), identify ONE graph that is NOT an appropriate choice to represent the information?
    •  Pie Chart
    • Why do you think it's not appropriate? 
    •  The figures on the pie chart is rounded off so it is not accurate. If it is not accurate it is not appropriate.
    • What makes you think the 3 remaining graphs are appropriate?
    • The other 3 do not have figures that are rounded off so they are accurate and hence appropriate for showing the data.

  1. Based on your reason, which is inaccuracy 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?
