Answer:
The MAD is: 2
Step-by-step explanation:
First, you add all the terms together. So we get 49.
Then, we divide 49 by the amount of terms. There are 7 terms, so we do 49/7.
We get 7. Now we have to find out the distance between each point and the mean, which is seven.
- 8-7= 1
- 7-5= 2
- 12-7=5
- 7-4=3
- 7-5=2
- 8-7=1
- 7-7=0
Now, we add all the distances together. We get 14.
Now, we divide 14 by the amount of terms, which is 7. 14/7 is 2.
The answer is b.
