# Concept of Average and it Uses

## Definition of Average

The arithmetic mean is defined as the sum of all numbers in a collection divided by the number of numbers present in the collection.

To put it another way, the average is the ratio of the total number of observations to the sum of all provided observations.

As a result, the average formula is as follows:

**Average = Sum of the Observations/Number of Observations**

## What is the Concept of Average

A single number out of list taken as a representative of all this numbers in the list, is a basic concept of average as it is clearly explained itself in this line.

What is Percentage and Why we Use it in Maths

Averages are used to represent a large number range with a single number. It is a graphical representation of all the numbers in the data set. The average is computed by adding all of the data values and dividing them by the number of data points.

The average age of the students in a class is calculated by taking the age of each student in the class and averaging it to give a single value for the average age of the students in a class. When dealing with quantities with changing values, the average is computed and a single value is used to represent the values. Understanding average allows us to quickly summarize the available data.

## Why We Use Average

Average has a wide range of applications in our daily lives. A large set of student grades, the changing price of stocks, a location’s weather data, and the income of different people in a city are all examples for which we can calculate an average.

For Example, the average mark of a class is calculated by averaging the marks of the students in that class in a specific subject. There is a need to know the overall performance of the class rather than the individual performance of each student. The average is useful in this case.

The sum of the values divided by the individual values equals the average of a set of values. In addition, average is used in situations where values change. The temperature of a location is calculated by averaging the temperature of that location over the course of the season.

Making decisions based on a single piece of data or a vast group of facts can be tough at times. As a result, the average value is used to represent all of the values in a single number.
