1. What is Range?

The range is the difference between the maximum and minimum values in a dataset. It's a simple measure of statistical dispersion that shows how spread out the values are.

2. How Does the Calculator Work?

The calculator uses the basic range formula:

Where:

• \( Max \) — The maximum value in the dataset
• \( Min \) — The minimum value in the dataset

Explanation: The range gives you the span between the highest and lowest values, providing a quick sense of the data's variability.

3. Importance of Range Calculation

Details: Range is fundamental in statistics for understanding data spread. It's used in quality control, finance, weather forecasting, and many other fields to assess variability.

4. Using the Calculator

Tips: Enter the minimum and maximum values. The maximum must be greater than the minimum. The calculator will compute the range between them.

5. Frequently Asked Questions (FAQ)

Q1: What does a large range indicate?
A: A large range indicates that the values in the dataset are spread far apart, showing high variability.

Q2: What are the limitations of range?
A: Range only considers the two extreme values and ignores how other values are distributed, making it sensitive to outliers.

Q3: Can range be negative?
A: No, range is always non-negative as it's the difference between maximum and minimum values.

Q4: How is range different from standard deviation?
A: Range only uses two values, while standard deviation considers all data points and their distance from the mean.

Q5: When is range most useful?
A: Range is most useful for quick assessments of variability and when the dataset is small or doesn't contain outliers.
