Watch: Mean, Median, Mode, and Range Explained Clearly

Key idea

Report n, the attribute and units, a center, a variability measure, and the shape. Choose by shape: skewed or outliers → median and IQR; roughly symmetric → mean is fine. Then say it as a sentence about the real situation.

Sample problems

Ten students scored on a 15-point quiz: 8, 9, 9, 10, 10, 10, 11, 11, 12, 12. How many observations, and what was measured?
Find the mean of the quiz scores.
Find the median of the quiz scores.
Compare the mean and the median. What does the comparison suggest about the shape?

Common mistakes to watch for

Answered ‘12’ with nothing else. The count alone does not say what was counted or in what units.
Dropped the units. Both answers are in minutes and should say so.
Reported only the range. On this data the range is dominated by one value and badly overstates the typical spread.

The answer key explains each one, so you can tell what a wrong answer means.
