Calculate Quartile Deviation for Ungrouped Data
Analyze Your Data Distribution with Our Quartile Deviation Calculator
Understanding the spread of your data is essential for statistical analysis, especially when comparing different data sets. Quartile Deviation, also known as the Semi-Interquartile Range, is a useful measure that provides insight into the variability of your data. Our Quartile Deviation Calculator is designed to simplify the calculation process, offering a quick and accurate way to analyze your data distribution. In this blog, we’ll explore how the calculator works and why it’s a valuable tool for anyone dealing with data.
What is Quartile Deviation?
Quartile Deviation measures the spread of the middle 50% of your data. It is calculated as half of the difference between the first quartile (Q1) and the third quartile (Q3). The Quartile Deviation provides a clear view of the dispersion of your data, focusing on the central portion and reducing the impact of outliers. This makes it an ideal measure of variability for skewed distributions.

Example Calculation
Let’s say you enter the following data: 76, 78, 78, 79, 81, 83, 88, 90, 160. After selecting two decimal places and clicking “Calculate,” the calculator provides the following results:
- First Quartile (Q1): 78.00
- Third Quartile (Q3): 88.00
- Interquartile Range: 10.00
- Quartile Deviation: 5.00
- Coefficient of Quartile Deviation: 0.06
Additionally, the calculator displays each step of the calculation, helping you understand how the results were derived.
Benefits of Using a Quartile Deviation Calculator
