What is the mode of the following data?
40, 20, 25, 20, 25, 27, 25, 26, 27, 29
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 25
The mode of a set of data is the value that occurs most often. Counting how many times each value appears:
25 appears 3 times
20 and 27 appear twice each
26, 29 and 40 appear once each
No other value occurs three times, so the mode is 25.
