What are measures of dispersion: How to calculate range, variance, Quartile and standard deviation

What are measures of dispersion

Dispersion or Spread is the extent to which the observations vary about their mean in a dataset. The quantity that measures a dispersion in a data set is known as measure of dispersion. It is used to check variability/spread of data i.e. to know how much homogenous or heterogeneous the data is. The measure of dispersion are of two types that is absolute and relative dispersion.

Type of measures of dispersion

An absolute measure of dispersion is one that measures dispersion in terms of the same units as the unit of data. if the unit of data is meter, kilogram or mile then measure of dispersion will be in the same unit.

A relative measure ofContinue Reading
