Quizplus · Accepted Answer

The standard deviation is the most appropriate descriptive measure of variability that is based on the concept of a deviation about the mean. The standard deviation measures the average distance of individual observations from the mean, indicating how much the data points vary from the central tendency of the sample. The range, interquartile range, and absolute value of the range do not take into account the individual deviations from the mean, making them less appropriate measures of variability.
