About this average & median calculator
Find the mean, median, range endpoints, and count of a number list. Separate numbers with commas or whitespace. The mean is the sum divided by count; the median is the middle value, or the average of the two middle values. Use this workspace to prepare a result you can review before putting it to use. All processing takes place on your device, without an account or an upload of your inputs. Check the examples to understand the expected output, read the limitations for the supported scope, and reset the form when you want to start a separate task.
How it works
Separate numbers with commas or whitespace. The mean is the sum divided by count; the median is the middle value, or the average of the two middle values.
Try these examples
2, 4, 6, 8
Count 4; mean 5; median 5; minimum 2; maximum 8
1 1 7
Mean 3; median 1
Limitations & privacy
Use 1–10,000 numbers from -1 trillion to 1 trillion. Commas separate values, so enter 1000 rather than 1,000 for one thousand. Floating-point rounding applies; no weighted average or mode.
Inputs and results stay in this browser. Only tool identifiers are stored for your recently used tools. You can clear that history from the directory.
