Dispersion measured by using extremes is a better approach than dispersion measured by using the distance between a score and its central point.

Question

Quizplus · Accepted Answer

Dispersion measured by using extremes (such as range or interquartile range) only takes into account the highest and lowest scores, and therefore may not accurately represent the spread of scores in between. Dispersion measured by using the distance between a score and its central point (such as variance or standard deviation) takes into account all scores, and is a more comprehensive measure of dispersion.
