You could...

4, 8 , 8 , 7, 9, 8, 8, 12

Mean = 8 (4+8+8+7+9+8+8+12/8 = 64/8 = 8)
Median = 8 (7+9/2 = 16/2 = 8)
Mode = 8 (8 occurs 4 times)
Range = 8 (12-4=8)

Or you could use:
4, 8, 8, 5, 11, 8, 8, 12
4, 8, 8, 6, 10, 8, 8, 12

But there is a fundamental flaw with all these sets. You must organize your data set from smallest to largest before making your median calculation.


Anyway, I may have given Don's answer a "thumbs up" too soon because it worked and it was simple. But why not this answer:

5, 6, 8, 8, 8, 8, 8, 13

(I know I could have thrown in a 7&9 combo, but we're really only looking for the highest possible number. Is 13 the highest we can go?)
