Answer 2

To find: average of given numbers

Given data : $3,7,8,7,4,9,10,12$

Solution :

• Average is the arithmetic mean.

• It is the ratio of sum of all the numbers given in data to the total number of observations.

• Formula:  $Average =\frac{\text { sum of all the observations }}{\text { total of observations }}$

• Here, sum of observations = $60$

• Total number of observations = $8$

• Substituting values in above formula,

         $\begin{array}{r}\text { Average }=\frac{60}{8} \\=7.5\end{array}$

Hence , average of given data is $7.5$ .
