Interquartile Range (IQR): How to Find and Use It - Statistics by Jim
The interquartile range (IQR) measures the spread of the middle half of your data. It is the range for the middle 50% of your sample. Use the IQR to assess the variability where most of your values lie. Larger values indicate that the central portion of your data spread out further.

Interquartile Range (IQR) in Statistics
The Interquartile Range (IQR) is a measure of statistical dispersion. It represents the range encompassing the middle 50% of a dataset. Unlike the total range (the difference between the maximum and minimum values), the IQR focuses on the core of the data, making it less sensitive to extreme values or outliers.
