Which of the following would NOT be used to graphically compare two data sets?

When you want to compare two data sets graphically, you choose charts that reveal differences or relationships between the sets. A bell curve represents the distribution of a single dataset—it's a single normal distribution shape and doesn't directly show how two datasets relate or differ on the same scale. In contrast, a scatter plot pairs observations from the two datasets so you can see correlation or patterns, a line chart can display both data series over a common axis to compare trends, and a box plot presents each dataset’s distribution side by side, highlighting differences in medians and spread. Because the bell curve doesn’t inherently display a comparison between two datasets, it’s not used for that purpose.
