Please note that this is only one possible way to correct the given histogram — there are many other possible ways to do it.

b Consider the given line graph.

The scale on the vertical axis of the given graph has very small increments that are not equal. To redraw the graph to make it not misleading, let's set the vertical axis to start at and end at with increments of one unit.

We can see now that the mean hourly wage has been increasing by minimal amounts, which is something that cannot be seen in the original graph. Please note that this is only one possible way to correct the given line graph — there are many other possible ways to do it.
