Single Variable Statistics Review

To find the [[1]], add up all of the numbers, then divide by how many numbers there are. To find the [[2]], first put the numbers in order from least to greatest, and then find the middle number. To find the [[3]], look for the most common number. Which term best completes the definition above?
