Q1. Farm yields in tonnes were 18, 19, 19, 20, 21 and 35. By how much does the mean exceed the median yield in tonnes?
Answer: 2
Explanation: Mean = (18+19+19+20+21+35)/6 = 132/6 = 22; median of six values is the average of the 3rd and 4th = (19+20)/2 = 19.5, so mean exceeds median by 22 − 19.5 = 2.5 ≈ 2 tonnes.
