Question

18;4;5;6;18;9;5;20 what is the median and mean

Answer 1

Answer:

Mean=10.62 and median=7.5

Step-by-step explanation:

Mean=

$\frac{18 + 4 + 5 + 6 + 18 + 9 + 5 + 20}{8} = \frac{85}{8} = 10.62$

ascending order- 4,5,5,6,9,18,18,20

n=8(even)

Median =

$( \frac{n}{2} )th + ( \frac{n}{2} + 1)th$

$( \frac{8}{2})th + ( \frac{8}{2} + 1)th = \frac{4th + 5th}{2} = \frac{6 + 9}{2} = \frac{15}{2} = 7.5$

Here's your answer.

Hope it helps you.
