Array:mean method bug #44

Closed IsmailM closed 8 years ago

IsmailM commented 8 years ago

Firstly the following seems to be a bug

require 'statsample'
[1, 2].mean => 1

This should be 1.5...

See https://github.com/SciRuby/statsample/blob/master/lib/statsample.rb#L62

i.e. That section should be 

def mean
  self.sum.to_f / size
end

Thanks for reporting, @IsmailM. Can you open a pull request with that fix?
