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 graph
Why do you think it's not appropriate?
It is not appropriate as the data in it are rounded off (as shown in the bottom right hand corner of the graph), and it is not that simple to interpret the data there.
What makes you think the 3 remaining graphs are appropriate?
They can accurately show data and the data in it is not rounded off and it is easier to interpret the data.
