Average and its application in daily life.

The average is used to summarise the group of data in a single value. It is very useful to hold the data of the grouped data in an averaged form.

Uses of average in daily life:

• To determine the performance of the different classes within a school, instead of comparing the marks of each student of each class we just find the average marks of a particular class and compare it with the average of the other.
• Even the per capita income of a country is also a perfect use of average in daily life. Where the income of a country is measure by the average of the income of the citizens of the country. As it is very difficult to compare the income of every citizen with others. So we use the average of it.

Average is the mean value of any of the data given which can be calculated as:

$Average=\frac{Sum~of~ the~ observations}{Number ~of~ observations}$
