6.
Put them on order from least to greatest.
5, 5, 6, 6, 6, 7, 7, 8, 9
The middle number is the median.

The median of this number set is 6.

To find the median I first put all the numbers in numerical order-- 5, 5, 6, 6, 6, 7, 7, 8, 9-- and choose the number in the middle which is 6.

If this is incorrect, please, don't refrain to tell me. Thank you.
