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.
The IQR and standard deviation are both measures of data dispersion, but they have distinct differences. The IQR is a non-parametric measure that is more robust and less affected by outliers, while the standard deviation is a parametric measure that assumes a normal distribution.
Opportunities and Realistic Risks
The IQR offers numerous benefits, including:
The IQR is widely used in various fields, including finance, healthcare, and education. It is used to identify outliers, detect data skewness, and calculate quartiles.
