Calculate the arithmetic mean, count, and sum of a comma-separated list of numbers.
| Average | – |
| Count | – |
| Sum | – |
Use this calculator for an unweighted arithmetic mean of a list: test scores, measurements, or any equally important numbers. Each entry counts once. For grades with different credits, use the weighted-average calculator instead.
Separate the numbers with commas. Entries that are not valid numbers are skipped. The mean is sum ÷ count. An empty list after filtering is rejected.
Spaces around commas are allowed. Semicolons and line breaks are not treated as separators here.
Values: Numbers separated by commas, for example 10, 20, 30.
Average: Arithmetic mean of the parsed numbers.
Count: How many valid numbers were read.
Sum: Total of those numbers.
