# A group of students was asked, "How many hours did you watch television last week?" Here are their responses: 7, 5, 16, 20, 17, 9, 18, 15. Find the Mean Absolute Deviation (M. A.D.) for these students.

The mean is the average so add all six numbers together and then devide it by how many numbers there are (6).

16+11+7+18+19+5=76 76/6=12.6666 or 12.7
I think it is 12.7 when you round it to the nearnest 10

Step-by-step explanation:

Mean = 16 + 11 + 7 + 18 + 19 + 5 / 6

Mean = 76 / 6

Mean = 12.66

7 and 16

Step-by-step explanation:

they are both in the middle

12.6

Step-by-step explanation:

6+16+5+16+13+12+20

=22+21+25+20

=43+45

=88

There are 7 responses.

88/7=12.6  (rounded to the nearest tenth.)

6+16+5+16+13+12+20= 88
88/7= 12.6
15.3

Explanation: so to get the mean, add all of the numbers together ( you should get 107) then divide by the amount of numbers given to you, which is 7. This give you 15.28...
Round t the nearest tenth an you get 15.3

4.78125

Step-by-step explanation:

Step 1

Find the mean

Mean = Sum of Terms/Number of Terms

Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8

= 107/8

= 13.375

Step 2

Find the Mean Absolute Deviation

Mean Absolute Deviation formula = |x - Mean|/n

Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8

Mean Absolute Deviation = 4.78125

Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125
