What is the Interquartile Range (IQR) Calculator?

The Interquartile Range (IQR) Calculator helps you measure the statistical spread of a dataset by calculating Q1 (first quartile), Q3 (third quartile), and the IQR. The IQR represents the range within which the middle 50% of your data falls, making it a useful tool for identifying variability and potential outliers. This calculator is valuable for students, researchers, and data analysts who want to quickly assess the distribution of their data without manual calculations.

How to Use:

1. Enter Data: Input your numerical dataset separated by commas (e.g., 5, 7, 8, 12, 15).
2. Click “Calculate”: The calculator computes Q1, Q3, and the IQR.
3. Review the Result: Use the quartile values and IQR to analyze variability, detect outliers, or summarize the dataset.
