Show HN: Go statistics library with 100% code coverage and no dependencies

I'm not sure why you think using standardized formulas is incorrect, there are certainly cases to use a mean average. There are other times you may want to use geometric mean, harmonic mean, mode, median, etc... and the library doesn't force anyone to use a specific function for the analysis, it just provides the tools to be used as needed.

Saying this is my high school homework is quite rude, it's a project I've been working on for several years along with several other contributors. It's cloned hundreds of times a day and quite obviously of benefit to many people and organizations.

This library is used as a dependency in many projects like cockroachdb, mongodb, etc... and has a lot of tests to verify it's correct. Not having dependencies ensures that the entire library is well tested and removes the need to track down bugs far down the dependency graph.
