Question

Which of these is the formula for computing the Z score?

		= (Score - Mean) / Standard Deviation
		= (Score x Mean) / Standard Deviation
		= Square Root of the Sum of Squared Mean Differences
		= Square Root of (Score - Mean) Squared

Answer 1

Answer #1

Z score standardized with respect to location and scale. Hence we need to subtract the mean from original score and divide with standard deviation.

Therefore the formula of z score is =

(Score - Mean) / Standard Deviation
