Question

Mr. Pantera is going to make a histogram of the test scores from the last math test he gave. He plans to first organize the data into a stem-and-leaf plot and then make the histogram from the stem-and-leaf plot. The test scores are listed below.

79, 82, 65, 61, 94, 97, 84, 77, 89, 91, 90, 58, 83, 99, 71, 68, 51, 77, 87, 85

How many bars will his histogram have?

Answer 1

There will be 5 bars because if you have a stem and leaf plot, there will be intervals of 9.
