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?
I think that a Line Graph is not appropriate to represent the information.

Why do you think it's not appropriate?

I think that it is not appropriate as line graphs are used to show information that are collected over a period of time. The lines of a line graphs are also redundant.

What makes you think the 3 remaining graphs are appropriate?

A Bar Graph shows the value of the numbers more clearly than a line graph as a bar is thicker than a line, making it easier to be seen

A Pie Chart shows the percentage/fraction of the values of the numbers in a circle which is also easier to compare which value is more or less and the fraction/percentage of the value to the total number of values.

A pictogram is similar to a Bar Graph, except that the units are shown in pictorial form.
