Below are sample questions representative of the exercises included on this worksheet and related ALG2.219 Interpreting Center and Spread in Context skill assessments:

Problem 1Difficulty: Mastery

A data set of classroom noise levels (in decibels) is summarized. Median = 62 dB IQR = 8 dB

Which statement best interprets these values?

A62 dB is the mean noise level and 8 dB is the standard deviation.

B8 dB is the difference between the loudest and quietest moment.

CMost noise levels are exactly 62 dB.

DAbout half the noise readings are 62 dB or less and half are 62 dB or more; the middle 50% of readings span 8 dB.

Solution & Explanation:Median is the middle noise level; IQR is the spread of the middle half of decibel readings.

Problem 2Difficulty: Mastery

Two weather stations compare wind speeds (mph) during storms. Station A: mean 31, standard deviation 9 Station B: mean 28, standard deviation 9

Which statement is correct?

AStation A has more variable winds because its mean is higher.

BStation B has more variable winds because its mean is lower.

CStation A and B have the same typical variability (same standard deviation), but Station A has a higher average storm wind speed.

DStation B has a larger IQR because the standard deviations match.

Solution & Explanation:Equal SDs mean equal typical spread. Means compare average wind speed; 31 mph is higher than 28 mph.

Problem 3Difficulty: Mastery

An online course summarizes time spent watching lecture videos. Median = 26 minutes IQR = 19 minutes

Which statement is best supported?

A26 minutes is the average viewing time, and 19 minutes is the standard deviation.

BHalf the students watched 26 minutes or less and half watched 26 minutes or more; the middle 50% of viewing times span 19 minutes.

C19 minutes is the difference between the longest and shortest viewing time.

DMost students watched exactly 26 minutes.

Solution & Explanation:Median splits viewing times in half. IQR gives the spread of the middle half of viewing times, in minutes.
