The mean of the population on variable X is 5.00 and the standard deviation is 1.25. Suppose your value on variable X is 6.25. What is your z-score?

Answer 1

Z = (X - Mean) / Std Dev

Z = (6.25 - 5) / 1.25

Z = 1.25 / 1.25

Z = 1.00

Answer 2

z= (X-mean)/s = (6.25-5)/1.25= 1.25/12.5 = 1

z score = 1
