What Is Average Deviation Formula?

The formula for average deviation is utilized to determine how much individual observations differ from the mean of a data set. Presented below is the formula for computing the average deviation across n observations:

Average Deviation = 1/n x Σ|xi – x̅|

In this formula:

xi represents individual data points in the set.

x̅ denotes the mean of the data.

n is the count of data points in the set.

To enhance understanding, let’s explore a few examples demonstrating how to apply the average deviation formula effectively.

Average Deviation is an effective way to analyze the variability in the given data. It is the average of all deviations from a central point. Average Deviation measures the distance from mean or median. It is also called Average Absolute Deviation (or) Mean Absolute Deviation.

Mean– It is the average value of all the values in the data.

Median– It is the middle value in the data when the data is sorted from low to high.
