Box Plot




This is an example of a box plot. The box plot is a graphical way to show many features of a set of data. The plot shows the Minimum and Maximum. Apart from the min and max the box plot shows the IQR, or Interquartile Range. The IQR consists of Q1, Q2, and Q3. Q2 is the median of the set of data, and Q1 is 25% below Q2 and Q3 is 25% above Q2. This specific box plot shows the energy output of four different machines.
