A Math test has a mean of 51 and standard deviation of 5.0. Find the corresponding z scores for:

I. a test score of 64
II. a test score of 47
Answered by PsyDAG
Z = (score-mean)/SD

Insert the values and calculate.
Answered by Jennifer
Z = 64-51/5.0 = 13/5.0 = 2.6
Z = 47-51/5.0 = -4/5.0 = -0.8

Is this correct?
