1. How do you solve for median if the given data is even? For example: 3,1,2,3,1,1 (these given data is even.)

2. When do you use the formula n+1/2 (for odd number) and n+2/2 (for even numbers)? NOTE: My teacher said that the formula that I gave, is only applicable on finding the median. Can you give one example to prove your answer?
