What Is the Minimum and Maximum Calculator?
This tool scans any list of numbers and instantly returns the minimum (smallest value), the maximum (largest value), and the range — the distance between them. It also reports how many values you entered and their mean (average), giving you a quick statistical snapshot of your data set.
How to Use It
Type or paste your numbers into the input box, separated by commas or spaces (for example 4, 12, 7, 23, 9). Negative numbers and decimals are fully supported. Press calculate and the results appear immediately. There is no limit on how many values you can enter.
The Formula Explained
The minimum and maximum are simply the smallest and largest members of the set. The range measures the spread of your data and is found by subtracting the minimum from the maximum:
$$\text{range} = \text{max} - \text{min}$$
A small range means your values are clustered together; a large range means they are widely scattered. The mean is the sum of all values divided by the count.
Worked Example
Take the set 4, 12, 7, 23, 9. The smallest value is 4 (minimum) and the largest is 23 (maximum). The range is $$23 - 4 = 19.$$ There are 5 values, and the mean is $$(4 + 12 + 7 + 23 + 9) \div 5 = 55 \div 5 = 11.$$
FAQ
Can I use decimals and negative numbers? Yes. Values like \(-3.5\) and \(2.75\) are handled correctly.
What separators are allowed? Commas, spaces, or both. The calculator splits on any combination of commas and whitespace.
What is the difference between range and the data itself? Range is a single number describing how spread out your data is, while the min and max identify the actual extreme values present in the set.
