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
Z Score
A statistical measurement that describes a value's relationship to the mean of a group of values, expressed in terms of standard deviations from the mean.
Standard Deviation
A statistic that measures the dispersion or variability of a dataset relative to its mean.
Raw Score
An original, unmodified score obtained in a measurement or test.
- Calculate raw scores from z scores, standard deviations, and means.

Final Answer :
C
Explanation :
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.
