Step 1: Definition of the median

             Median:

                    The median of a set of data is the middlemost number in the set.

                    The median is also the number that is halfway into the set.

  •   If there is an odd number of observations, the median is the middle value.

                  let's say n is the number of observations

                          If n is odd, The median = \frac{n+1}{2}th term

  •   If there is an even number of observations, the median is the average of the two middle values.

                      If n is even, The median = \frac{\frac{n}{2}+\left(\frac{n}{2}+1\right)}{2}  


Step 2: Arrange the data in either ascending order or descending orderr

              Ascending order

                  0, 1, 5, 6, 6, 12, 19


Step 3: Count the number of observations and find the median of the given data

            There are 7 observations

                n = 7 is a odd number

            So, the median = \frac{n+1}{2}=\frac{7+1}{2}=4^{th}\ term


            See the 4th term in the data

                        0, 1, 5, 6, 6, 12, 19


                Hence, the median = 6
