Histograms A Histogram is a vertical bar graph in which each interval is represented by the width of the bar and the frequency is represented by the height of the bar. Let’s look at the test score example again. Test Scores of 32 Students Test Scores ( Intervals) Frequency

Another Histogram The following table represents the number of miles per gallon obtained by 40 drivers. Miles per Gallon for 40 Drivers Mileage (Miles per Gallon) Frequency

Cumulative Histogram The following table represents test scores of 240 students in a school. Test Scores Frequency Now let’s make a Cumulative Frequency Table. Cumulative Histogram Test Scores Frequency

More Cumulative Histograms The following table represents the number of book students bring home. Cumulative Number of Books Brought Home Number of Books Frequency

More Cumulative Histograms The following table represents the number of book students bring home. Cumulative Number of Books Brought Home Number of Books Frequency
