Problem is, the description is talking about the sample standard deviation, while the kata expects population standard deviation, which are different things.
Nice kata :) Random tests needed. If you would need some help I'm always glad to help out.
That will be great thanks very much for the offer! I've made it available to contributors.
The tests are using
Test.expect(bool, msg)which simply expectsboolto be truthy, which allows my solution to pass ;)You want to change it to
Test.assertEquals(actual, expected, msg)Thanks dcsmith for pointing that out for me! Hopefully it's better now.
Looks good! :)
