A deviation score measures the distance of a number from the mean:

true or false why>

15)

Given a normally distributed variable (x), the formula: z = (x - µ) ÷ can be used to determine the value of x at a specific point on the x-axis, if you know the z-score.

true or false

Solution

13) This is true, deviation scores are expressed as difference from mean,

15) True, this formula is for calculating the standard score (z score) froma given value (x), but the same formula can be used to calculate the reverse, i.e, the x value from a given z score.
