Answer 2

The mean of 10 7 13 20 & 15 is 13.

Solution:

The mean data can be calculated by dividing the sum of all data divided by the total number of data. Mean would be sometimes called as arithmetic mean. Mean can also be said in terms of average of all numbers.

Symbolically it can represented as $\bold{\overline{x}=\frac{\sum x}{n}}$

$\sum x$ – Summation of data values given.

n – Total number of values given.

Therefore, Mean =$\bold{\frac{\text { Sum of all data }}{\text { Total number of data }}=\frac{10+7+13+20+15}{5}=\frac{65}{5}=13}$
