Notes
The difference of maximum and minimum values of each series. This difference is called the ‘Range’ of the data.
In case of batsman A, Range = 117 – 0 = 117 and for batsman B, Range = 60 – 46 = 14. Clearly, Range of A > Range of B. Therefore, the scores are scattered or dispersed in case of A while for B these are close to each other.
Thus, Range of a series = Maximum value – Minimum value.
The important measures of dispersion, which depend upon the deviations of the observations from a central tendency are mean deviation and standard deviation.
