Answer 1

Answer:

Median: 11.5 Mean: 12

Step-by-step explanation:

For median, if you have 2 numbers in the middle you add them together and divide by 2.

12 + 11 = 23

23 / 2 = 11.5

For mean, you just add all the numbers together and divide by the total amount of numbers present.

(18 + 6 + 20 + 12 + 11 + 4 + 10 + 15) / 8 = 12
