The interquartile range (IQR) is only based on the middle 50% of the data and is not affected by extreme values or outliers. The range is sensitive to extreme values because it is based on the difference between the largest and smallest values. The standard deviation and coefficient of variation are both affected by extreme values because they are based on the deviation of each data point from the mean.
