__ Measure of Dispersion__

#### Measure of dispersion is the variation of the statistical data from its central value.

**Types Of Measure of Dispersion**

**Types Of Measure of Dispersion**

####
**1.**** **range

#### 2.mean deviation

#### 3. Variance

#### 4. Standard Deviation

####
** **__Range__

The range is
calculated by simply taking the difference between the maximum and
minimum values in the data set. However, the range only provides
information about the maximum and minimum values and does not say
anything about the values in between. It simplest measure of dispersion. ####
__Mean Deviation__

Another method is to calculate the average difference between each
data point and the mean value, and divide by the number of points
to calculate the mean deviation.####
__Variance __

A better way to measure dispersion is to square the differences
before averaging them. This measure of dispersion is known as the
variance.

**Standard Deviation**The square root of the variance is known as the standard deviation. The standard deviation and variance are widely used measures of dispersion.
