When a sample size equals one mod four, this value is equal to the H-Spread, or the difference between the hinges.
When a sample size equals one mod four, this value is equal to the H-Spread, or the difference between the hinges. In a normal distribution, this value is supposed to equal approximately 1.35 times the standard deviation, covering about two-thirds of a standard deviation both above and below the mean, and, like the median absolute deviation, this statistic is robust. This value is represented as the width of the box in a boxplot. Name this statistic which is calculated by subtracting the the median of the lower half of a data set from the median of the upper half.
