attr_reader, in it's common usage, creates instance variables and 
defines a method by which you can read them.

Class Test
    def initialize(num)
       @test=num
    end

    def test
       @test
    end
end

If you were to use attr_reader instead, your class definition would be

Class Test
    attr_reader :test
    def initialize(num)
       @test = num
    end
end
