{given the following List [5,3,8,2,7] which value is the median?} - 2 - 3 + 5 - 7 - 8

{given the following List [2,3,5,7,8] which value is the median?} - 2 - 3 + 5 - 7 - 8

{given the following List [2,3,5,7,8] which value is the average?} - 2 - 3 + 5 - 7 - 8

{given the following list [1,2,3,4,5,6,7] which statements are true?} + The median is exactly the average - The median is smaller than the average - the average is smaller than the median + 4 is the average + 4 is the median - 7 is the median - for any list of elements the median is smaller than the number of elements.
