Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
Paste or type a list of numbers and this average calculator returns the full set of summary statistics: mean, median, mode, range, sum, count, minimum, maximum and both the population and sample standard deviation. Numbers can be separated by commas, spaces or new lines, so you can drop in a column from a spreadsheet without cleaning it up first. Non-numeric tokens are ignored gracefully and reported so you know what was skipped, and you can copy the whole result set with one click. All of it runs in your browser with nothing uploaded.
Short answers for the questions people usually have before trying a utility like this.
Population standard deviation divides by n and treats your list as the whole population. Sample standard deviation divides by n minus 1 and treats the list as a sample from a larger group. The tool shows both.
Any token that is not a valid number is skipped, and the tool tells you how many were ignored, so a stray label or empty cell will not break the results.
The mode is only defined when a value repeats. If every number is unique the tool reports no mode; if several values tie for the most frequent it lists all of them.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
