Question

calculate the standardized score for the following data value. assume the mean = 100 and the standard deviation = 25: x = 60, z =

Answer 1

The standardized score for the given data value is -1.6

(or, z = -1.6)

Explanation:

Mean = M = 100

Standard Deviation = S = 25

Data point = x = 60,

finding z,

`z =(x-M)/S\\z = (60-100)/25\\z = -40/25\\z=-8/5\\z=-1.6`

Hence

z = -1.6
