Yes, the IQR can be used for skewed data, as it is a non-parametric measure that is less affected by outliers and data skewness.
Opportunities and Realistic Risks
The IQR offers numerous benefits, including:
So, what exactly is the Interquartile Range? In simple terms, the IQR is a measure of data dispersion that shows the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. It is calculated by arranging all data values in ascending order and finding the median, which splits the data into two equal parts. The 75th percentile (Q3) represents the median of the upper half, while the 25th percentile (Q1) represents the median of the lower half. The IQR is then calculated by subtracting Q1 from Q3.
