How to Use This Calculator
- Enter the dataset using spaces or commas to separate numeric values.
- Review the minimum, maximum, range, and midrange once results appear.
- Use the range to evaluate overall spread and the midrange for a quick central estimate.
- Combine with quartiles, variance, or standard deviation for deeper distribution insights.
Formulas
Range = maximum − minimum
Midrange = (maximum + minimum) ÷ 2
These measures highlight overall spread and provide a fast, rough center estimate.
Range is sensitive to extreme values; pair it with robust measures like the interquartile range when outliers may be present.
Frequently Asked Questions
Can the range be negative?
No. Range is always zero or positive because it subtracts the smallest value from the largest.
What if all values are identical?
The range is zero and the midrange equals the shared value.
Do I need to sort the data?
No sorting is required. The calculator scans values to find the min and max directly.
How does range compare to standard deviation?
Range uses only the extremes, while standard deviation considers every data point. Use them together for a fuller picture.
