The range is calculated by subtracting the lowest value from the highest value in a distribution. Therefore, it measures the distance between the upper and lower limits of a set of values. The IQR measures the distance between the 25th and 75th percentiles and is therefore more sensitive to central tendency. The variance and standard deviation measure the spread of data around the mean, rather than the range between upper and lower limits.
