What type of graph would be the most appropriate to use to
graph the information?

Answer 1

To represent given data, the most suitable graph is a histogram, which shows the frequency distribution across specified score ranges, helping to visualize where most test performances fell.

Step-by-step explanation:

The most appropriate type of graph to represent the science test grades is a histogram.

A histogram is used to show the frequency of score intervals, and it is particularly useful for showing the distribution of scores over a set of intervals.

Since the data is given in predefined ranges and frequency counts, a histogram enables a quick visual interpretation of where most scores are concentrated and how the other scores are distributed.

or example, we can see that most scores on this exam were in the range of 70-89, indicating the most frequent test performance interval, and fewer scores were in the 60-69 and 90-100 ranges.

In constructing the histogram, each bin would represent the score intervals (50-59, 60-69, 70-79, 80-89, 90+), and the height of each bar would correspond to the frequency of scores within each interval.
