Answer:
1.25
Step-by-step explanation:
Give the data:
X : 1 1/2 ___ 0 _____ 4 ______ 2 1/2
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8
xbar = 8/4 = 2
|x - xbar| :
|1 1/2 - 2|= 1/2
|0 - 2| = 2
|4 - 2| = 2
|2 1/2 - 2| = 1/2
Therefore,
MAD = (1/2 + 2 + 2 + 1/2) / n
MAD = 5/4
MAD = 1.25
