Answer 1

✓ Given

→ Data :-

7 , 9 , 10 , 11 , 14 , 15

✓ To find

» Mean of the following data

✓ Solution

$\bf \: mean = \frac{sum \: of \: the \: given \: data}{total \: number \: of \: the \: data}$

Here The sum of the data is :

7 + 9 + 10 + 11 + 14 + 15 = 66

The total number of data given is 6

So Let's calculate the mean of the data !!

= 66/6 » 11
