Range Calculator
Statistics plays an important role in mathematics, data analysis, business, education, and science. When working with a set of numbers, it is often necessary to understand how the values are distributed. Key statistical measures such as minimum, maximum, range, mean, median, and mode help summarize and analyze data effectively.
Our Range Calculator is a simple and powerful online tool that allows you to quickly calculate these important statistical values. By entering a list of numbers separated by commas, the calculator automatically computes the range and several other statistics in seconds.
This tool is perfect for students, teachers, researchers, analysts, and anyone working with numerical data.
What Is Range in Statistics?
In statistics, the range is the difference between the largest and smallest numbers in a dataset.
Range Formula
Range = Maximum Value − Minimum Value
The range shows how spread out the numbers are.
Example
Dataset:
3, 8, 12, 17, 25
Minimum value = 3
Maximum value = 25
Range = 25 − 3 = 22
The larger the range, the more spread out the data is.
Features of the Range Calculator
This calculator does more than just compute the range. It also provides several useful statistical results.
1. Minimum Value
The smallest number in the dataset.
Example:
Numbers: 5, 9, 12, 3
Minimum = 3
2. Maximum Value
The largest number in the dataset.
Example:
Numbers: 5, 9, 12, 3
Maximum = 12
3. Range
The difference between the maximum and minimum values.
Example:
Range = 12 − 3 = 9
4. Total Count
The total number of values entered.
Example:
Numbers: 5, 7, 9, 12
Total numbers = 4
5. Sum
The sum is the total of all numbers in the dataset.
Example:
5 + 7 + 9 + 12 = 33
6. Mean (Average)
The mean is the average value of the dataset.
Formula:
Mean = Sum ÷ Total Numbers
Example:
Numbers: 4, 6, 8
Mean = (4 + 6 + 8) ÷ 3 = 6
7. Median
The median is the middle value when numbers are arranged in ascending order.
Example:
Numbers: 3, 5, 7, 9, 11
Median = 7
If there are an even number of values, the median is the average of the two middle numbers.
Example:
2, 4, 6, 8
Median = (4 + 6) ÷ 2 = 5
8. Mode
The mode is the number that appears most frequently in the dataset.
Example:
Numbers: 3, 7, 7, 9, 10
Mode = 7
If no number repeats, the dataset has no mode.

Example Calculation
Let’s see how the calculator works with an example.
Input Numbers
5, 12, 3, 99, 47
Results
Minimum Value = 3
Maximum Value = 99
Range = 99 − 3 = 96
Total Numbers = 5
Sum = 166
Mean = 166 ÷ 5 = 33.2
Sorted Numbers:
3, 5, 12, 47, 99
Median = 12
Mode = No mode (no repeated numbers)
