Below are sample questions representative of the exercises included on this worksheet and related 8.7 Statistics for Scientific Data skill assessments:

Problem 1Difficulty: Mastery

A lab group recorded voltage across a sensor output pin in 7 trials (V): 32, 9, 11, 19, 6, 22, 4. Which option gives the correct mean (nearest tenth), median, and range?

Amean 14.7 V; median 15 V; range 28 V

Bmean 11.0 V; median 11 V; range 28 V

Cmean 14.7 V; median 11 V; range 28 V

Dmean 14.7 V; median 11 V; range 32 V

Solution & Explanation:Mean: add then divide and round. Median: middle after sorting. Range: max − min. Pick the option matching all three.

Problem 2Difficulty: Mastery

Each option is a possible set of V results for voltage across a battery pack after 10 minutes. Which data set has median 9 V, mode 9 V, and range 9 V?

A6, 7, 9, 9, 9, 9, 10, 13, 14

B5, 7, 9, 9, 9, 9, 10, 13, 14

C5, 7, 8, 9, 9, 9, 10, 13, 14

D25

Solution & Explanation:Compute the requested statistic(s) for each option: median is the middle value, mode is most frequent, and range is max − min.

Problem 3Difficulty: Mastery

In repeated trials of voltage across two points on a breadboard circuit (V), one value is unusually high: 12.5, 6.6, 10.9, 7, 42, 14.1, 6.7. Which statistic BEST describes a typical trial?

AMedian (it is less affected by an outlier)

BMean (average)

CRange (max − min)

DMode (most frequent value)

Solution & Explanation:The mean is pulled toward an outlier, but the median stays near the middle of the data, so it represents a typical result better.
