### eLearning Lesson 1 Task 1: Choice of Graphs Toby Gail [06]

• 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?
• What makes you think the 3 remaining graphs are appropriate?

The pie chart is not an appropriate choice to represent the information.
I think that its not appropriate because it is rounded off and also because it is represented in degrees. It is hard to calculate the actual amount when it is represented in degrees.
The remaining 3 charts are appropriate as it is more accurate and the actual amount can be inferred.

#### 1 comment:

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?

On the other hand, you mentioned that it's hard to calculate the actual amount when you need to 'reverse' the action - find out the figures. Yes, you have pointed out one of the 'challenges' that we might face when we need to figure exact figures when given a pie chart.

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?
