Question

7. Find the mean of the following data set.

(a) 24
(b) 24.5
25, 26, 21, 29, 22, 24, 27, 24
(c) 24.75
(d) 25.25

Answer 1

Answer: 24.5

Explanation:

The definition of mean in maths is adding all the values up (25 + 26 + 21 + 29 + 22 + 24 + 27 + 24), and then dividing the final sum by the number of values there are to be added up. In this case, there are 8 values that had to be added up and the final sum was 198. In other words, it's 198/8 = 24.5
