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.
