Final answer:
A histogram is a graphical representation of data that shows the frequency of each score or range of scores. It can be used to determine the mean score, the range of scores, and the number of students who scored above a certain threshold.
Step-by-step explanation:
A histogram is a graphical representation of data that shows the frequency of each score or range of scores. It consists of contiguous boxes on a horizontal axis, labeled with the scores, and a vertical axis, labeled with frequency or relative frequency.
A histogram can be used to determine the mean score, the range of scores, and the number of students who scored above a certain threshold.
To find the mean score, you would calculate the sum of all scores and divide it by the total number of students. To determine the range of scores, you would subtract the minimum score from the maximum score.
And to find the number of students who scored above a certain threshold, you would count the number of scores that are greater than or equal to the threshold.
