Answer:
6 is your median and the average is 11.7
Explanation:
to find the median, you simply list the numbers in order from greatest to least and determine which is in the middle.
(3, 4, 5, 6, 16, 20, 28 - with 6 there is three numbers on the left and three numbers on the right)
to determine the average, you add all the numbers up and divide by how many numbers you have
3 + 4 + 5 + 6 + 16 + 20 + 28 = 82
82 divided by 7 is 11.71428571 (when simplified its 11.7)
