Which Measure of Variability Is Most Useful? Why

Question

Examlex · Accepted Answer

The Answer is The most useful measure of variability is the standard deviation. This is because it takes into account the spread of all the data points from the mean, giving a more comprehensive understanding of the variability within the dataset. The standard deviation also allows for easy comparison between different datasets, as it is expressed in the same units as the original data. Additionally, the standard deviation is used in many statistical calculations and is a key component in determining the significance of results in hypothesis testing. Overall, the standard deviation provides a more complete and informative measure of variability compared to other measures such as range or interquartile range.
