Dispersion in statistics refers to the extent to which a distribution is stretched or squeezed. Common measures of dispersion include range, variance, and standard deviation. Here’s a brief overview of the range as a measure of dispersion:
Range
Definition: The range is the simplest measure of dispersion. It is defined as the difference between the maximum and minimum values in a data set.
Formula: Range=Maximum Value−Minimum Value
Coefficient of Range = Maximum Value-Minimum Value / Maximum Value + Minimum Value
