No, IQR is only applicable to numerical data. For categorical data, other metrics such as chi-square or cross-tabulation can be used to analyze relationships and patterns.
IQR is only used in finance
IQR is a simple and accessible metric that can be used by anyone with basic statistical knowledge. It's not just for data analysis professionals.
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.
