IQR is used in various fields, including healthcare, quality control, and social sciences. It's not limited to finance alone.
Calculating IQR involves arranging a dataset in ascending order and finding the median (Q2) of the data. The median is the middle value of the dataset. The lower quartile (Q1) and upper quartile (Q3) are then found, which are the 25th and 75th percentiles, respectively. The IQR is calculated by subtracting Q1 from Q3. This simple yet powerful metric provides a quick and easy way to understand the spread of data and identify potential issues.
