1. What is Range?

The range is the difference between the largest and smallest 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 range formula:

Where:

• Maximum Value — The largest value in the dataset
• Minimum Value — The smallest value in the dataset

Explanation: The range gives the span between the extreme values in your data, 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, research, and many other fields to assess variability.

4. Using the Calculator

Tips: Enter your maximum and minimum values. The calculator will compute the difference between them. Ensure your maximum is greater than your minimum for valid results.

5. Frequently Asked Questions (FAQ)

Q1: What does a large range indicate?
A: A large range indicates that the values in your 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: When should I use range?
A: Use range when you need a quick, simple measure of spread, especially for small datasets or when extremes are particularly important.

Q4: What's the difference between range and interquartile range?
A: Interquartile range measures the middle 50% of data, making it less sensitive to outliers than the full range.

Q5: Can range be negative?
A: No, range is always non-negative as it's the difference between the maximum and minimum values.
