How to Calculate the Average

The average, also known as the arithmetic mean, is a central value of a set of numbers. It's widely used in mathematics, statistics, and everyday life to represent the typical value of a dataset.

Average Formula

The formula for calculating the average is:

\[ \text{Average} = \frac{\text{Sum of all numbers}}{\text{Count of numbers}} \]

Where:

• Sum of all numbers is the total of all values in the dataset
• Count of numbers is the number of values in the dataset

Calculation Steps

1. Add up all the numbers in your dataset to get the sum
2. Count how many numbers are in your dataset
3. Divide the sum by the count

Example Calculation

Let's calculate the average of the numbers 2, 4, 6, 8, and 10.

1. Sum up the numbers: \[ 2 + 4 + 6 + 8 + 10 = 30 \]
2. Count the numbers: 5
3. Divide the sum by the count: \[ \text{Average} = \frac{30}{5} = 6 \]

Therefore, the average of 2, 4, 6, 8, and 10 is 6.

Visual Representation

A visual representation can help understand the concept of average. Here's a diagram showing the numbers and their average:
