FORMULA TO BE IMPLEMENTED

Mean is a measure of central tendency.

If an variable X takes the values

$x_1, x_2, x_3,..........,x_n$

Then

$\sf{ \: Mean \: is \: denoted \: by \: \bar{x} \: }$

And defined as

$\displaystyle \: \bar{x} = \frac{ \: x_1 + x_2 + x_3 + ....... + x_n \: }{n}$

TO DETERMINE

The mean of the observations

$7 ,16, 130, 51, 100, 80, 10, 25, 8, 10, 6$

EVALUATION

The given observations are

$7 ,16, 130, 51, 100, 80, 10, 25, 8, 10, 6$

Total number of observations = 11

So the required mean

$\displaystyle \: = \frac{ 7 + 16 + 130 + 51 + 100 + 80 + 10 + 25 + 8 + 10 + 6 }{11}$

$\displaystyle \: = \frac{443}{11}$

$= 40.27$
