Descriptive Statistics and Psychological Testing
www.csus.eduthe standard deviation of scores obtained by the standardization sample (sd). Z-scores have a mean of 0 and a standard deviation of 1. A score that is one standard deviation below the mean has a Z-score of -1. A score that is at the mean would have a Z-score of 0. The formula for transforming a raw score into a Z-score is a follows:
z-SCORES
www.westga.eduz-Scores establish relationships between score, mean, standard deviation Example o Population: μ = 65 and X = 59 corresponds to z = -2.00 o Subtract 65 from 59 and find deviation score of six points corresponds to z value of -2.00 o (X - μ) / z = σ Example o Population: σ = 4 and X = 33 corresponds to z = +1.50
