Median of the given data is 4, 5, 7, 0, -3, -5, -6, 5, 13, -4 .

Arrange in as Ascending order = -6, -5, -4, -3, 0, 4, 5, 5, 7, 13 

N = 10 which is even

Hence, median = \(\frac{(\frac{n}{2})th\;term\;+\;(\frac{n}{2} +1)th\;term}{2}\) 

                      = \(\frac{5th\;term\;+\;6th\;term}{2}\) 

                      = \(\frac{0\;+\;4}{2}\)  = 2
