Question

find mean and median of the given data 20 14 7 25 18 13 19 10 9​

Answer 1

Answer:

median =18

mean=sum of all observations +no. of observations

Answer 2

Answer:

Step-by-step explanation:

Median:

Arrange all data in ascending order.

7,9,10,13,14,18,19,20,25.

Cutting one number from each side.

We get the middle number as 14.

Therefore, Median = 14

Mean:

$\frac{Sum of all observations}{Total no. of observations} = \frac{20+14+7+25+18+13+19+10+9}{9} = \frac{135}{9} =15$

Therefore, Mean = 15
