Question

Find the median
X 20 25 29 33 38 42 43
F 6 20 24 28 15 4 2 1

Answer 1

33 and 10.5

Explanation:

The median is the middle number in the data set arranged in ascending order.

If there is no exact middle value then it is the average of the 2 numbers either side of the middle.

X 20 25 29 33 38 42 43

↑ middle number

Thus the median = 33

Arrange set F in ascending order.

F 1 2 4 6 15 20 24 28

↑ middle between 6 and 15

Thus the median =
`(6+15)/(2)` =
`(21)/(2)` = 10.5

Answer 2

The median for X is "33"

The median for F is "10.5"
