## What is deviation in research?

A standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.

## How do you find the standard deviation of a study?

Steps to Finding the Standard Deviation Subtract the mean from each of the data points. Take each of the differences and square them. Find the variance, which is the average of the squared differences. Calculate the square root of the variance, which is the standard deviation.

## What is standard deviation example?

The standard deviation measures the spread of the data about the mean value. For example, the mean of the following two is the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30. However, the second is clearly more spread out. If a set has a low standard deviation, the values are not spread out too much.
