? The median:
First, we arrange the values in an ascending order

          Second, we choose the middle value

Case 1:
  The number of values is odd then the median is the
                          value in the middle

 Example: Find the median of 42 , 23 , 17 , 30 , 20
                                  Solution

                Arrange 17 , 20 , 23 , 30 , 42
                            The median = 23
