Below are sample questions representative of the exercises included on this worksheet and related 7.147 Communicating conclusions with evidence skill assessments:

Problem 1Difficulty: Mastery
Two random samples summarized distances walked in minutes. Sample A: mean 52, MAD 6. Sample B: mean 55, MAD 7. Which conclusion is best supported?
ASample B is guaranteed to be higher for every person because its mean is 3 minutes greater.
BSample A has the higher center because its MAD is smaller.
CThe samples have exactly the same distribution because the MADs are close.
DSample B has a slightly higher center, but the difference of 3 minutes is small compared with the MADs, so the data sets likely overlap.
Solution & Explanation:The mean of Sample B is 3 minutes higher than Sample A. Since the MADs are 6 and 7 minutes, the typical variation is larger than the mean difference, so a cautious conclusion is best.
Problem 2Difficulty: Mastery
Two schools compared math contest score summaries. School A: mean 72, median 73, IQR 8. School B: mean 78, median 79, IQR 7. Which conclusion is best supported?
ASchool A tends to score higher because its IQR is larger.
BThe schools have identical centers because their IQRs are close.
CSchool B tends to score higher by about 6 points on mean and median, with similar variability.
DSchool B is much more variable because its IQR is 7.
Solution & Explanation:School B's mean is 78 compared with 72, and its median is 79 compared with 73. The IQRs, 7 and 8, are close, so variability is similar.
Problem 3Difficulty: Mastery
Two quiz-score summaries are given. Group A: mean 20, mean absolute deviation 1. Group B: mean 20, mean absolute deviation 4. Which claim is best supported?
AGroup B has the higher mean because its mean absolute deviation is larger.
BThe groups have the same mean, but Group A is more consistent because its mean absolute deviation is smaller.
CThe groups have identical scores because the means are equal.
DGroup A is less consistent because 1 is less than 4.
Solution & Explanation:The means show the same center. Mean absolute deviation measures typical distance from the mean; a smaller MAD of 1 means Group A's scores are more consistent.
