    Common Misconceptions

    The 1.5 IQR rule is a statistical method used to detect outliers in a dataset. It calculates the difference between the 75th percentile (Q3) and the 25th percentile (Q1) and then multiplies this difference by 1.5. Any data point that falls outside of this range is considered an outlier. This simple yet effective method provides a clear threshold for identifying data points that deviate significantly from the rest of the data.
