Do Now 1)Construct a box and whisker plot: 10, 13, 14, 16, 16, 18, 20, 23, 24, 24, 27, 34 2)For a set of data, the interquartile range is 22 and the upper quartile is 73, what is the lower quartile? Frequency Histograms A frequency histogram is a graph that displays a set of data that has been grouped into intervals. Student Heights Frequency Histograms need to have: 1) Titles 2) Labeled Axes 3) Bars That Touch 4) Breaks (only if the intervals dont start at 0) Student Heights 1. 2)Sarahs mathematics grades for one marking period were 85, 72, 97, 81, 77, 93, 100, 75, 86, 70, 96, and 80. Cumulative Frequency The word cumulative means total. A cumulative frequency chart keeps a running total of the number of values in a set of data. The intervals will look slightly different than the ones from yesterday. 3) Complete The Chart 4)The cumulative frequency histogram below shows the distribution of scores on a math test. Find the number of scores in each original interval. 5)The cumulative frequency histogram below shows the ages of people standing on line in a cafeteria. Find the number of scores in each original interval. 6)The following cumulative frequency histogram shows the distances swimmers completed in a recent swim test. Based on the cumulative frequency histogram, determine the number of swimmers who swam between 200 and 249 yards. Determine the number of swimmers who swam between 150 and 199 yards. Determine the number of swimmers who took the swim test. 7) Homework Histograms Homework
