IQR offers several benefits, including:

The IQR value can be used to assess the spread of a dataset, detect outliers, and understand the distribution of data.

Who is this topic relevant for?

Opportunities and realistic risks

• Assess data variability
• Identification of data outliers and anomalies
• Believing IQR is only useful for identifying outliers
1. Thinking IQR is a substitute for other statistical measures

Data enthusiasts, researchers, and professionals in various fields, including:

2. Overreliance on IQR as a sole measure of data dispersion

IQR is a statistical measure that calculates the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. This range helps identify the middle 50% of the data, which is less sensitive to extreme values. IQR is calculated using the following steps:
