Quizplus · Accepted Answer

Standard deviation is the most commonly encountered measure of variability as it provides a measure of how spread out the data is from the mean. Range is not as useful because it only considers the difference between the highest and lowest values, while ignoring everything in between. Mean and mode are measures of central tendency, not variability.
