Answer:
8
Explanation:
Mode is the number that appears most in the list. Median is the number in the middle when the numbers are ordered up from smallest to greatest. If you put the numbers in order, you get: 3, 6, 6, 7, 8, 8, 8, 9, 10, 12, 15. * appears 3 times, and the center is at 8. Thus, 8 is both a median and mode.
