Below are sample questions representative of the exercises included on this worksheet and related ALG2.210 Outliers and Effects on Statistics skill assessments:

Problem 1Difficulty: Mastery

A data set has mean 50 with one high outlier. After removing the outlier, the mean becomes 47. Which conclusion is most reasonable?

ARemoving an outlier always increases the mean.

BThe IQR must have doubled.

CThe standard deviation must have increased.

DThe outlier was pulling the mean upward; the median probably changed less than the mean did.

Solution & Explanation:A drop in mean after removing one value indicates that removed value was above the original mean and was pulling the mean up; medians usually move less.

Problem 2Difficulty: Mastery

Caleb recorded the number of goals scored in each practice scrimmage during field hockey drills. Data: 43, 44, 45, 46, 48, 48, 49, 51, 52, 52, 55, 55, 57, 148 Remove the outlier using the 1.5×IQR rule. How much does the mean change (original mean minus cleaned mean)? Round to the nearest hundredth.

Solution & Explanation:Outlier = 148. Mean(original) = 56.642857142857146. Mean(cleaned) = 49.61538461538461. Change = 56.642857142857146 − 49.61538461538461 = 7.027472527472533, which rounds to 7.03.

Problem 3Difficulty: Mastery

Nolan timed how many minutes it took to solve a set of practice problems during a study hall. For a data set, Q1 = 7 and Q3 = 13. What is the lower outlier fence Q1 − 1.5×IQR?

Solution & Explanation:IQR = 13 − 7 = 6. Lower fence = 7 − 1.5×6 = -2.0.
