Answer: The left chart.
Step-by-step explanation:
Between the two charts, the data displayed on the left is misleading. This data is misleading because the y-axis does not have a consistent scale. In the right chart, each increase in the y-axis goes up by 15. However, in the left chart, we see + 20, + 20, + 15, + 10, + 5.
This changes the look of the graph, making the differences between the years along the x-axis appear much different than they actually are. This means that the left data is misleading.
