Question

mr. teacher wanted to display the grades of the students performance on their last test. which of the following displays could he use to display the test scores? check all that apply.

☐ box plot
☐ histogram
☐ dot plot
☐ pie graph
☐ bar graph

Explanation:

• Box Plot: Shows the distribution of data (median, quartiles, outliers) for test scores.
• Histogram: Displays the frequency of test scores in intervals.
• Dot Plot: Represents individual test scores with dots, showing frequency.
• Pie Graph: Used for showing proportions of categories, not ideal for test scores (continuous/numeric data).
• Bar Graph: Can compare scores (e.g., scores of different groups/students). So Box Plot, Histogram, Dot Plot, and Bar Graph are suitable; Pie Graph is not.

Answer:

A. Box Plot, B. Histogram, C. Dot Plot, E. Bar Graph
