Descriptive Statistics: It is used to describe the spread of continuous variables such as age, weight, or blood pressure in a population. Identifying Outliers: Values that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR are considered outliers. This helps in identifying unusual cases that may warrant further investigation. Risk Assessment: When assessing risk factors, the IQR can be used to compare the distribution of continuous variables between different groups. Trend Analysis: It can help in analyzing trends over time by comparing the IQR of different time periods.
