Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Step-by-step explanation:
We can solve x through simple algebra.
x + 5 = 2
x = 2 - 5
x = -3
x - 10 = 22
x = 22 + 10
x = 12
x - 27 = 8 + 10
x - 27 = 18
x = 18 + 27
x = 45
-11 + x + (-48) = 25
-11 + (-48) + x = 25
-59 + x = 25
x = 25 + 59
x = 84
x - (-16) = 12 + 13
x + 16 = 25
x = 25 - 16
x = 9
Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).
