Min Max Calculator — Find Minimum and Maximum Values
Enter a list of numbers to instantly find the minimum, maximum, range, mean, and median — with an interactive number line showing where each falls relative to the spread of data.

How does this calculator work?
Min is the smallest value, max is the largest; Range = max − min. Enter a list of numbers (comma, space, or semicolon separated) to find min, max, range, mean, and median — with a number line visualization showing where each falls.
Formula
How this is calculated
Finding the minimum and maximum of a data set is the first step in understanding its spread. The minimum is the smallest value and the maximum is the largest. Their difference — the range — gives the total extent of the data: a range of 38 means values span 38 units from bottom to top. These three statistics are computed in a single pass and require no particular order in the input.
Min and max are the most interpretable measures of spread but are highly sensitive to outliers: a single extreme value can inflate the range and make it unrepresentative of the typical spread. For data with potential outliers, the interquartile range (IQR = Q3 − Q1) is a more robust alternative, since it covers only the middle 50% of sorted values.
The calculator also shows mean (sum divided by count) and median (middle value of the sorted list). Comparing mean and median reveals skewness: if the mean is much higher than the median, the data is positively skewed with a long upper tail; if much lower, it is negatively skewed.
Frequently asked questions
Min is the smallest value; max is the largest; range = max − min. For {4, 8, 15, 16, 23, 42}: min = 4, max = 42, range = 38. The range tells you the total spread of the data in one number.
Yes. Negative values, decimals, and mixed positive/negative sets all work. Separate values by commas, spaces, or semicolons. Duplicate values are allowed and counted.
Finding min and max is a descriptive statistic. Min-max normalization uses those values to rescale all data points to [0, 1] via x_norm = (x − min) / (max − min), so the smallest value becomes 0 and the largest becomes 1. This calculator reports the statistics; for full normalization, use a dedicated data-normalization tool.
