Question

a group of 25 students participated in a science competition. their scores are below. score (points) number of students 30 - 39 5 40 - 49 7 50 - 59 6 60 - 69 4 70 - 79 3 would a dot plot or a histogram best represent the data presented here? why? histogram, because a small number of scores are reported individually histogram, because a large number of scores are reported as ranges dot plot, because a small number of scores are reported individually dot plot, because a large number of scores are reported as ranges

Explanation:

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
