Since we have a numerical data set, we can split it into intervals and find the frequency of each interval. Therefore, another way to display the data is by using a histogram. To do so, let's first create a frequency table by using five intervals, beginning with 51-60.
Score
Frequency
51-60
3
61-70
2
71-80
4
81-90
7
91-100
4
Let's now display the data in a histogram.
Please note that this is only one possible way to represent the data — there are many other possible ways to do it.

Data Display We Used Previously
Since a stem-and-leaf plot allows us to see data in numerical order and the data distribution, we used it previously to display the given data set.
