Answer:
2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)
since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.
