The ages (in years) of some students are 1, 3, 9, 9, 4, 9, 2, 3, 9, 8, 7, 4, 3, 2, 2 and 9. What is the mode of the ages?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 9
The mode is the value that occurs most often, so each age is counted.
9 occurs 5 times
2 and 3 occur 3 times each
4 occurs 2 times
1, 7 and 8 occur once each
9 occurs most often, so the mode is 9.
