Consider the data set 2, 2, 5, 5 and 8. Which statements about the mode of this data set are true? Select all that apply.

Explanation

Both 2 and 5 occur twice while 8 occurs once, so two values tie at the highest frequency and the set has two modes. Naming only one of them leaves out a value that is exactly as frequent, and a tie at the top is reported in full rather than broken by preferring the smaller or the larger value.
