## What is standard deviation conceptually?

Definition: **Standard deviation** is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the **standard deviation** and greater will be the magnitude of the **deviation** of the value from their mean.

## What does the mean deviation tell you?

**Mean Deviation tells us** how far, on **average**, all values are from the middle.

## What if standard deviation is greater than mean?

A sample's **standard deviation** that is of **greater** magnitude **than** its **mean** can indicate different things depending on the data you're examining. ... A smaller **standard deviation** indicates that more of the data is clustered about the **mean**. A **larger** one indicates the data are more spread out.
