📊 Interquartile Range Calculator
Calculate the interquartile range (IQR) of a data set, which measures statistical dispersion.
What is the Interquartile Range?
The interquartile range (IQR) is the difference between the third quartile (Q3, 75th percentile) and the first quartile (Q1, 25th percentile): IQR = Q3 - Q1. It represents the spread of the middle 50% of the data and is robust against outliers, making it a preferred measure of variability for skewed distributions.
