Given:
Data set =
To find:
The absolute mean deviation for the given set.
Solution:
We have,
Mean of the data set is
Now,
The formula for mean absolute deviation (MAD) is
Therefore, the mean absolute deviation for the given set of data is x.
Answer:
x=-6
Y=4
Step-by-step explanation:
81 1/2
We plug a and c in to get: 9^2+1/2
9^2=81 and 81+1/2 is 81 1/2
