If number of values even:

5, 9, 2, 6, 7, 1. Sort by value: 1, 2, 5, 6, 7, 9. Median is the mean of middlest values: (5+6)/2=5.5 . Other method to find median = [(n+1)/2]th value. (n is the number of values. (6+1)/2=3.5 median is 3rd value + 0.5*|difference between 3rd and 4th value| = 5 + 0.5*(6-5) = 5.5 .
