# Average Deviation Calculator

The average deviation formula helps in calculating the average deviation, which is the average of the absolute deviation (distance) of the data points from the mean of the data set.

## How to Find Average Deviation Calculator?

**The average deviation** is defined as the average deviation of the data points from a center point.

**Average deviation = ∑(|x _{i} - x|) / N**

Where x_{i} is individual values in the sample, and x is the mean or an average of the sample, N is the number of terms in the sample.

The** **mean value** **or average of a given data is defined as the sum of all observations divided by the number of observations. The mean is calculated using the formula:

**Mean or Average(x) = (x _{1} + x_{2} + x_{3}...+ x_{n}) / nMean or Average(x) = (x_{1} + x_{2} + x_{3}...+ x_{n}) / n**

Where n = total number of terms, x_{1},_{ }x_{2},_{ }x_{3}, . . . , x_{n} = Different n terms

**Solved Example:**

Find the average deviation for the following set of data: {51,38,79,46,57}

**Solution:**

Given N =5

Average deviation = ∑(|x_{i} - x|) / N

Mean(x) = 51 + 38 + 79 + 46 + 57 / 5 = 54.2

Average deviation = (|51 − 54.2|) + (|38 − 54.2|) + (|79 − 54.2|) + (|46 − 54.2|) + (|57 − 54.2|) / 5

= 11.04

Therefore, the average deviation is 11.04

Similarly, you can try the calculator to find the average deviation for the following data sets:

- 21,14,16,8,2,4,15,8
- 25,1,7,15,6,14,14,25,7
