Math 304 Extra Practice with box and whisker plots 1. Use a Box and Whisker Plot to represent the following the number of hours students worked each week. Given their work week involved 0, 0, 15, 18, 20, 25, 27, 30, 30, 40, 42 2. Use a Box and Whisker Plot to represent the following average daily temperature in degrees Fahrenheit: 100 F, 210 F, 150 F, 80 F, 120 F, 140 F, 210 F, 280 F 3. Use a Box and Whisker Plot to represent student teacher ratings on nine items that fall on a scale of 0-500. Given the following ratings: 397, 412, 423, 428, 433, 440, 441, 448, 460 4. Make up a data set that has an interquartile range of 20.

Solutions-The graphs should have a title, be scaled appropriately with a label on each of the horizontal axes.

1. Min = 0, Max = 42, Q1 = 15, Median = 25, Q3 = 30

2. Min = 8, Max = 28, Q1 = 11, Median = 14.5, Q3 = 21

3. Min = 397, Max = 460, Q1 = 417.5, Median = 433, Q3 = 444.5

4. One data set with an interquartile range of 5, 6, 8, 10, 7, 16, 20
