According to the textbook, the most commonly used measure of variability is the standard deviation. The reason for this is that it takes into account all the data points and gives a more representative measure of how spread out the data is compared to the mean. The range only considers the minimum and maximum values, while the variance is less intuitive and difficult to interpret compared to the standard deviation. The median is a measure of central tendency and not a measure of variability.
