Average calculator
Calculate arithmetic mean and keep the matching median and range alongside it.
What this calculator covers
Use this average calculator to find the arithmetic mean of a short list of values while keeping the median and range in the same view.
That combination is useful because the mean shows the balancing point of the set, while the median and range show whether the values cluster tightly or spread out.
Frequently asked questions
- When does the median give a more useful picture than the mean?
- The median is more informative when the data set contains extreme outliers. A single very large or very small value can pull the mean far from where most values sit, while the median stays at the middle of the sorted list regardless of outlier magnitude.
- How is range calculated?
- Range is the maximum value in the set minus the minimum value. It measures the full span of the data but says nothing about how the middle values are distributed.
- What is the difference between mean and average?
- In everyday use the words mean and average refer to the same thing: the sum of the values divided by how many there are. This is technically the arithmetic mean, distinguishing it from geometric or harmonic means used in other contexts.
- How many values can I enter?
- The calculator supports between 2 and 5 values. Select the count before entering your numbers and only the chosen values will be included in the statistics.

Walkthrough
Visual walkthrough
Average work starts with the same list of values, then branches into center and spread statistics.
01
Collect the selected values
4, 8, 15, 16, 23
Only the first chosen count of inputs contributes to the statistics.
02
Compute the arithmetic mean
66 / 5 = 13.2
Mean is the balancing point of the selected values.
03
Read median and range
Sorting the list reveals the middle value and the full spread from minimum to maximum.
Median 15, range 19
