Quizplus · Accepted Answer

The range is a measure of variability that is based on the difference between the highest and lowest values in a dataset. It is considered to be the most unstable measure of variability because it is highly sensitive to extreme values, which can lead to large changes in the value of the range. In contrast, measures like the mean, median, and semiquartile range are less affected by extreme values and are therefore considered to be more stable measures of variability.
