You can put this solution on YOUR website! There are 4 numbers and the mode is 8(the number repeated the most)
:
4 x 8 8
:
we are given that the median is 7, when we have an even number of numbers we average the two numbers in the middle
:
(x + 8) / 2 = 7
:
x = 6
:
the mean is (4 + 6 + 8 + 8) / 4 = 6.5
:
