Problem 1Difficulty: Hard
Set A (minutes spent waiting in the lunch line): 9, 10, 10, 10, 11, 11, 23. Set B (weights of backpacks in pounds): 18, 18, 18, 18.5, 19.5, 20.5, 20.5. Which statement is correct about the best measure of center for each set?
ASet A: Median = 10; Set B: Mean = 19
BSet A: Mean = 12; Set B: Median = 18.5
CSet A: Mean = 12; Set B: Mean = 19
DSet A: Median = 10; Set B: Median = 18.5
Solution & Explanation:Set A has an outlier, so the median of 10 is the better summary. Set B has no extreme value, so the mean of 19 is the better summary.
Problem 2Difficulty: Hard
Set A (cups of water students drank): 16, 16, 19, 21, 22, 23. Set B (number of laps swum): 24, 25, 26, 26, 27, 28, 29, 55. Which statement is correct about the best measure of center for each set?
ASet A: Mean = 19.5; Set B: Median = 26.5
BSet A: Mean = 19.5; Set B: Mean = 30
CSet A: Median = 20; Set B: Median = 26.5
DSet A: Median = 20; Set B: Mean = 30
Solution & Explanation:Set A has no extreme value, so the mean of 19.5 is the better summary. Set B has an outlier, so the median of 26.5 is the better summary.
Problem 3Difficulty: Hard
Compare these two data sets. Set A (meal prices in dollars): 6.25, 6.25, 7, 7, 7.5, 7.75, 14.25. Set B (minutes classmates spent on a warm-up): 29, 30, 30, 31, 31, 33, 47. Which choice correctly matches each set with its better measure of center?
ASet A: Mean = 8; Set B: Mean = 33
BSet A: Median = 7; Set B: Mean = 33
CSet A: Median = 7; Set B: Median = 31
DSet A: Mean = 8; Set B: Median = 31
Solution & Explanation:Set A has an outlier, so the median of 7 is the better summary. Set B has an outlier, so the median of 31 is the better summary.
