Question

QUESTION 6 Consider the following data: 2 2 2 3 3 3 5 5 the mean and median for this data are: A.3 & 3.125 B.3.125 & 3 C.3 125 & 2 D.3&3

Answer 1

B

Explanation:

the mean is calculated as

mean =
`(sum)/(count)` =
`(2+2+2+3+3+3+5+5)/(8)` =
`(25)/(8)` = 3.125

the median is the middle value of the data set, arranged in ascending order ( smallest to largest )

If there is no exact middle then the median is the average of the values on either side of the middle.

2 2 2 3 3 3 5 5

↑ middle is between 3 and 3

median = (3 + 3) ÷ 2 = 6 ÷ 2 = 3
