Question

For the following data set, calculate the mean and median. Any non-integer answers should be rounded to

the nearest tenth.
5,5, 9, 10, 13, 16, 18, 20, 22, 22​

Answer 1

(a)Mean=14

(b)Median=14.5

Explanation:

Given the data set:

5,5, 9, 10, 13, 16, 18, 20, 22, 22​

(a)Mean

`\bar{x}=(5+5+9+10+13+16+18+20+22+22)/(10) \\=(140)/(10) \\Mean=14`

(b)5,5, 9, 10, 13, 16, 18, 20, 22, 22​

Since we have two terms in the middle, we take the average to obtain the median.

Median

`=(13+16)/(2)\\=(29)/(2)\\Median=14.5`
