The ages (in years) of some students are 12, 2, 2, 3, 8, 7, 4, 3, 2, 2 and 9. What is the mode of the ages?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 2
The mode is the value that occurs most often, so each age is counted.
2 occurs 4 times
3 occurs 2 times
4, 7, 8, 9 and 12 occur once each
2 occurs most often, so the mode is 2.
