Drop scores, measurements, or prices separated by spaces, commas, or line breaks. This page is a list average, not a ratio of two terms.
Parsing and stats run in this tab. The list is not uploaded to a sheet service.
How to use
- Paste numbers separated by spaces, commas, or new lines.
- Read count, sum, mean, and median.
- Check min and max for outliers.
How it works
Mean is the sum divided by how many finite numbers parsed. Median is the middle of the sorted list, or the average of the two middles when the count is even.
Tokens that are not finite numbers are skipped. An empty list returns an error instead of a fake zero mean.
Examples
Class scores
8, 9, 10, 7 yields a mean of 8.5 and a median of 8.5 on four tests.
Sensor log
A noisy series shows min and max beside the mean so a spike is obvious.
FAQ
Are commas decimal marks?
Separators can be commas between numbers. Decimal dots parse as JavaScript numbers. Use dots for fractions.
Is this a weighted average?
No. Every finite number has equal weight. Repeat a value if it should count twice.
How is this different from a ratio?
Averages summarize a list. Ratios compare two terms or solve a proportion.
