Quizplus · Accepted Answer

The standard deviation is measured in the same units as the mean, making it a useful measure for comparing the variability of different datasets that are measured in different units.

Answer: A 
 The standard deviation is relatively robust to the influence of outliers, meaning that extreme values in the dataset will not disproportionately affect its value.

Answer: C and D 
 These statements are both incorrect. The standard deviation is not a measure of dispersion around the median, and it does not have a natural, concrete meaning in and of itself.
