The dispersion measures the spread of numeric data. the measures include range, quartiles, quantiles, and percentiles.
Range – The range of a set of values is the difference between the largest and smallest values in the set.
Quantiles – Quantiles are the points taken at regular intervals of a data distribution, dividing it into essentially equal size consecutive sets.
Quartiles – If the total set is divided into four equal parts then it’s known as quartiles.
Percentile – If we divide the set into 100 equal parts or quantiles then it’s known as a percentile.
