IN MATH: 1. n. a standard normal score. 2. n. a score normally distribution with a mean of 0 and a standard deviation of 1.
3. n. for a sample or population, the ratio of the difference between a score and the mean and the standard deviation. See below.

To compute z, use the formula

 (Enter negative two as "-2.") score, x: mean, : standard deviation, s: the mean from the score. the (x - ) by s
4. n. the factor used to multiply the standard deviation to produce the "distance" a score is to be from the mean.

The formula to compute x:

 (Enter negative two as "-2.") z-score, z: mean, : standard deviation, s: the z-score and standard deviation. + zs
IN ENGLISH: 1. as defined above.
