A box plot is a way of graphing data into groups or intervals. It is a way of making data much easier to interpret. This box plot shows four different machines and the energy they displace. Each box represents the different machines and their size is determined by the energy output. This is graphed and expressed making it easy to understand that machine number three is the largest in energy output.
