# Average

Simple gem to calculate mean, median and mode from an array.

## Installation

Add this line to your application's Gemfile:

    gem 'average'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install average

## Usage

Get Median

    $ [3, 4, 5, 2, 3, 1].mean

    $ 3.0

Get Mode

    $ [2,4,6,14,21,24,229,24,24,39].mode

    $ 24

It gives back an array due that could be possible to have more than one mode in a array

    $ [1, 2, 2, 2, 3, 3, 7, 7, 7, 9].mode

    $ [2, 7]

But if you want to have only a unique mode, you can use 'unique_mode' method (Only for Ruby versions bigger than 1.8.7 -> http://apidock.com/ruby/v1_8_7_72/Enumerable/max_by).

    $ [1, 2, 2, 2, 3, 3, 7, 7, 7, 9].unique_mode

    $ 2

Get Median

    $ [3,4,5].median

    $ 4

    

All methods described aboved can handle an array of integers, floats, strings or a mixed array with all of them

    

    $ [3, "4", 5, 2.0, 3, "1.0"].mean

    $ 3.0
