Question

superiority of dispersion​

Answer 1

Step-by-step explanation:

INTRODUCTION

The measures of central tendency are not adequate to describe data. Two data sets can have the same mean but they can be entirely different. Thus to describe data, one needs to know the extent of variability. This is given by the measures of dispersion. Range, interquartile range, and standard deviation are the three commonly used measures of dispersion.

Hope it's helpful for you!

Answer 2

Answer:

Standard deviation is superior to other measures because of its merits showing the variability which is important for statistical data. ... good measure of dispersion. In mean deviation we take the sum of deviations from actual mean after ignoring ± signs.
