The ages (in years) of eight students are 14, 15, 16, 15, 15, 17, 15 and 18. What is the mode of the ages?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 15
The mode is the value that occurs most often, so each age is counted.
15 occurs 4 times
14, 16, 17 and 18 occur once each
15 occurs most often, so the mode is 15.
