The Range Calculator quickly finds the minimum, maximum, and range of a data set. The range is the difference between the largest and smallest values, giving a simple measure of how spread out the numbers are.
This tool is especially helpful for students learning descriptive statistics, and for everyday uses like checking score spreads, comparing prices, or analysing performance data.
What does the calculator do?
- Accepts numbers: Enter values separated by commas or spaces.
- Finds the minimum and maximum values.
- Calculates the range (max − min).
- Displays all results clearly for easy interpretation.
- Copy results with one click for assignments or reports.
Worked examples
Example 1 — Test scores
Scores: 50, 65, 70, 80, 90
- Minimum = 50
- Maximum = 90
- Range = 90 − 50 = 40
Example 2 — Prices
Item prices: 3.50, 2.99, 4.25, 5.00
- Minimum = 2.99
- Maximum = 5.00
- Range = 2.01
Example 3 — Daily temperatures (°C)
Temperatures: 12, 15, 18, 20, 14, 22
- Minimum = 12
- Maximum = 22
- Range = 10
Why is it important?
- In school: The range is one of the first measures of spread taught in statistics.
- In real life: Helps compare data spreads — from sports results to household spending.
- In data analysis: Range provides quick insight into variability, before moving to more advanced measures like standard deviation.
Frequently Asked Questions
Q1: What does “range” mean in statistics?
It’s the difference between the largest and smallest values in a set.
Q2: Can I enter decimals?
Yes. Decimals work just like whole numbers.
Q3: What if I only enter one number?
The minimum and maximum will be the same, and the range will be 0.
Q4: Is range enough to describe variability?
Not always. It’s simple but ignores how values are distributed. For deeper analysis, statisticians use standard deviation and variance.
