Question

Find the mean deviation of 3 ,6 ,6,7,8,11,15,16​

Answer 1

Given data :

• 3 ,6 ,6 ,7 ,8 ,11 ,15 ,16

Data is already in ascending order so let's start answering.

We have to find the mean of Given data

`\sf \: Mean = (sum \: of \: all \: observations)/(number \: of \: observations) \\`

`\sf \: mean = (3 + 6 + 6 + 7 + 8 + 11 + 15 + 16)/(8) \\ \\ \sf \: mean = \cancel (72)/(8) \\ \\ \red{\underline{ \boxed{ \sf \: mean = 9}}}`

Hence

• Mean of Given data is 9
