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?
- The Pie Chart is NOT the appropriate choice to represent the information.
Why do you think it's not appropriate?
- It does not give the exact amount as it rounds the number up to the nearest whole number .
What makes you think the 3 remaining graphs are appropriate?
- All the other graphs are represented by using the number of countries and not the percentage to the total number of countries.

  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?
