Interquartile Range (IQR) - Definition and Explanation | TheStatsCalculator
Definition The interquartile range (IQR) measures statistical dispersion by quantifying the spread of the middle 50% of data. It is calculated as Q3 − Q1. Because it ignores the lowest and highest quartiles, IQR is robust to outliers and is frequently paired with the median.
