Range Calculator

The range is a measure of spread that tells you how far apart the largest and smallest values in a dataset are. It gives a quick sense of how dispersed or spread out your data is.

To calculate the range, subtract the minimum (smallest) value from the maximum (largest) value in the dataset. The formula is: Range = Max − Min. For example, for the dataset {2, 4, 34, 5}, the range is 34 − 2 = 32.

No. Because the maximum value is always greater than or equal to the minimum value, the range is always zero or a positive number. A range of zero means all values in the dataset are identical.

Range measures the spread between the highest and lowest values. Mean is the arithmetic average of all values. Median is the middle value when the dataset is sorted. Mode is the value that appears most frequently. Together, these statistics give a comprehensive summary of a dataset.

Enter your numbers separated by commas into the Number Set field and click Calculate. The calculator sorts the values, then computes the range, min, max, mean, median, mode, and total count — and displays the sorted ascending order in a table.

When multiple values appear the same number of times and most frequently, the dataset is considered multimodal. This calculator reports all mode values separated by commas in that case.

Yes. The Range Calculator accepts both positive and negative numbers. Simply include them in your comma-separated list, for example: -5, -1, 0, 3, 7.

Range is easy to calculate and provides a quick snapshot of data spread, but it only uses two values (min and max) and is heavily influenced by outliers. For a more robust measure of spread, consider using standard deviation or interquartile range alongside the range.
