What does IQR stand for?

• A. Interquartile Range
• B. Internal Quotient Range
• C. Interquartile Ratio
• D. Irregular Range

Answer: (A)

The IQR is a measure of how spread out the middle portion of the data is. It focuses on the central 50% by looking at the distance between the third quartile (the 75th percentile) and the first quartile (the 25th percentile). It’s calculated as Q3 minus Q1, and this makes it a robust indicator of variability because extreme values don’t have as much influence as they do on the overall range. IQR stands for Interquartile Range, which is the standard term. The other options aren’t used to describe this concept in statistics.
