Common questions about IQR
The IQR is a measure of variability, calculated by finding the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. To put it simply, the IQR is the middle 50% of the data, excluding the outliers. This is in contrast to the range, which includes all values from the minimum to the maximum.
The IQR offers several benefits, including:
