The IQR is a measure of the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. To calculate the IQR, you need to arrange the data in ascending order and find the middle value (Q2), which represents the median. The IQR is then calculated by subtracting the 25th percentile from the 75th percentile. This value represents the middle 50% of the data, excluding the outer 25% on each side.
