Question

50 POINTS!!!!!!!!!!!!!!!

28,45,12,34,36,45,19,20

Find the mean absolute deviation of this set of data. PLEASE PUT STEPS

Answer 1

10.125

Explanation:

Given the data :

28,45,12,34,36,45,19,20

The mean absolute deviation of the data is :

Σ|x - mean| / n

n = number of values = 8

Mean = Σx / n = 239 / 8

Mean = 29.875

Take the sum of the absolute value if the difference between each data value and the mean, then divide by the data size

Using a mean absolute deviation calculator ;

Mean absolute deviation = Σ|x - mean| / n = 10.125
