Lesson 8.1 Construct the graphical display for each given data set. Describe the distribution of the data. 1. Construct a box-and-whisker plot to display the number of miles from school that a number of randomly chosen students live. The data are 5, 10, 15, 12, 1, 14, 9, 15, 3, 10, 12, 15, 8, 14, 13, and 2. Analyze the given histogram which displays the ACT composite score of several randomly chosen students. Use the histogram to answer each question. ACT Composite Scores Analyze the given dot plot which displays the number of home runs by each of the girls on the softball team this season. Use the dot plot to answer each question. Softball Team Home Runs 4. How many more students had an ACT composite score between 15 and 20 than had a composite score between 30 and 35? Lesson 8.2 Create a dot plot of each given data set. Calculate the mean and median. Determine which measure of center best describes each data set. 5. The data are 13, 12, 12, 11, 17, 10, 11, 12, 14, 20, 15, 12, 18, 13, 12, 17, 14, and 11. 2. How many players scored more than 12 home runs? Analyze the given box-and-whisker plot which displays the heights of 40 randomly chosen adults. Use the boxand-whisker plot to answer each question. Heights of 40 Randomly Chosen Adults 6. Determine which measure of center best describes the data in each given data display. Then determine the mean and median, if possible. If it is not possible, explain why not. Results of Diving Expedition 3. Describe the distribution of the data in the box-andwhisker plot and explain what it means in terms of the problem situation.
Lesson 8.3 Calculate the IQR of each given data set. Determine whether there are any outliers in each set and list them. 7. The data are 60, 55, 70, 80, 20, 60, 105, 65, 75, 100, 55, 15, 115, 65, 70, 45, and 60. Calculate the mean and the standard deviation of each data set without the use of a calculator. SHOW YOUR WORK! 11. The data are 13, 14, 15, 15, 16, 16, 17, and 18. 8. Calculate the IQR of the data set represented in each box-and-whisker plot and determine whether there are any outliers in each data set. 12. The data are represented by a dot plot. Lesson 8.4 Calculate the mean and the standard deviation of each given data set using a graphing calculator. 9. The data are 3.5, 4, 5.5, 6, 6, 7, 7.5, 8, 9.5, and 10.5. 10. The data are represented by a dot plot.
