Scores that are one standard deviation above the mean = T score of 60, one standard deviation below the mean = T score of 40, two standard deviations above the mean = T score of 70, etc. T = z*10 + 50. We can also express norms in terms of percentiles: the score at or below which a specified percentage of scores in a distribution falls.
