Mr. Jacobs 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, 83, 99, 71, 68, 77, 87, 85

How many bars will his histogram have?

Answer:

The modal interval would be the range of numbers that include the most number of data points. So, looking at your information, there would be 3 numbers in the 60-69 range, 4 numbers that fall in the 70-79 range, 6 numbers that fall in the 80-89 range, and 5 numbers that fall in the 90-99 range. The interval with more data than any other is the 80-89 range therefore making it the mode interval.
