Quizplus · Accepted Answer

The interquartile range is the range of the middle 50% of the data and is a measure of variability that is less affected by extreme outliers than the range or variance. The midrange is the average of the minimum and maximum values and is not a measure of variability. The variance is a measure of how spread out the data is, but does not specifically refer to the middle 50% of the data. The mode is the most common value and does not provide information about variability.
