Question

Which change would affect the mode?
21, 19, 38, 24, 21, 3, 23, 21

eliminating all outliers

adding another data point

eliminating the high-end outlier

decreasing each number by 1

Answer 1

A mode is the number that occurs most often (21).

eliminating all outliers will not affect the mode (3 and 38)
eliminating the high-end outlier will not do it either (38)
decreasing each number by 1 does make the mode of 21 turns into 20..


I think decreasing it by 1 would be the closest

Answer 2

Thanks!
