Answer:
The mean absolute deviation means taking the actual value of each data term. For example: -7 would be 7. 10 would be 10. 26 would be 26. -98 would be 98. Nothing can be negative. Then, after you find the absolute deviation of each term, you can find the mean of the data set.
Step-by-step explanation:
Seventh grade: 183 + 187 + 204 + 215 + 196 = 985 There are 5 terms in the set so... 985 ÷ 5 = 197 The mean absolute deviation of the 7th grade data set is 197.
