If you know the z score,standard deviation(s),and mean (M),what formula would you use to compute the raw score (X)?
A)X = (z + s)÷ M
B)M = z(s)+ X
C)X = z(s)+ M
D)z = (M - X)÷ s

The formula for computing a raw score given the z score, standard deviation, and mean is X = z(s) + M. This means you multiply the z score by the standard deviation and then add the result to the mean. Therefore, choice C is the correct answer.
