Cumulative Frequency Tables and Histograms Unit 2, Day 4

A cumulative frequency column in a frequency table allows you to keep a running total of the frequencies in each category.

The list shows the average high temperatures for 20 cities on one February day. Make a cumulative frequency table of the data. 69, 66, 65, 51, 50, 50, 44, 41, 38, 32, 32, 28, 20, 18, 12, 8, 8, 4, 2, 2 Average Highs TalliesFrequency Cumulative Frequency

The data shows the ages of some hospital nurses. 33, 35, 23, 39, 23, 24, 34, 21, 57, 45, 57, 60, 45, 24, 31, 42, 61, 45, 35, 38 Make a cumulative frequency table of the data. AgesTalliesFrequency Cumulative Frequency

The table below lists the heights of students, in inches, in Mr. Munson’s 2nd period class. Fill in the cumulative frequency table above.

Construct a cumulative frequency histogram for this data.
