To compare student scores on the semester A and B math tests, the most useful data display would be the Double Bar Graph.

A Double Bar Graph is a visual representation that uses two parallel bars side by side to compare two data sets. In this case, the two data sets would be the scores of students on the semester A and B math tests.

To create a Double Bar Graph, you would need to follow these steps:

1. Gather the scores of students for both semester A and B math tests.

2. Organize the scores into categories or intervals. For example, you might have categories such as 0-20, 21-40, 41-60, etc. This grouping helps to simplify the data and make it easier to interpret.

3. Plot the categories on the x-axis (horizontal axis) of the graph.

4. On the y-axis (vertical axis), label it as the score or frequency of students.

5. For each category, draw two parallel bars side by side. One bar represents the scores of students on the semester A test, and the other bar represents the scores on the semester B test. The height of the bars corresponds to the number of students in each category.

By using a Double Bar Graph, you can visually compare the scores of students on the semester A and B math tests and easily identify any patterns or differences between the two sets of data.
