Answer

Brief Explanations:

A histogram is best as scores are reported in ranges. A dot - plot is used for individual data points, not grouped data. Since the scores are grouped into intervals (30 - 39, 40 - 49 etc.), a histogram is the appropriate choice to represent the frequency distribution of scores among the 25 students.

Answer:

Histogram, because a large number of scores are reported as ranges
