          • Q1 (25th percentile): The middle value of the lower half of the dataset.

            • Misconception: IQR is sensitive to outliers

            The interquartile range is a statistical measure that represents the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. To calculate the IQR, you need to arrange your data in ascending order and identify the middle values:

          Opportunities and Realistic Risks

          The Q1, Q3, and IQR are related but distinct measures. The Q1 represents the middle value of the lower half of the dataset, while the Q3 represents the middle value of the upper half. The IQR, on the other hand, calculates the difference between Q3 and Q1, providing a measure of the spread of data.

      Can the IQR be used with non-normal distributions?

      Misconception: IQR is a measure of central tendency

    • A narrow IQR (close to 0) indicates that the data is tightly clustered around the median.

      • Yes, the IQR can be used to analyze non-normal distributions, as it is more robust to outliers compared to the standard deviation.
