Discover the Midpoint Mystery: What is Interquartile Range in Statistics?

Common Misconceptions About Interquartile Range

Calculate the IQR by subtracting Q1 from Q3.

While both measures aim to describe the spread of data, IQR and Standard Deviation (SD) serve different purposes. SD is sensitive to outliers and measures the average distance of data points from the mean. IQR, on the other hand, is more robust and focused on the middle 50% of the data. Choose the appropriate measure depending on the characteristics of your dataset.
