... For such distributions, when N is sufficiently large, the empirical rule tells us that: (1) Approximately 68% of values are within 1 standard deviation of the mean o 68% of scores fall within the following interval: X ± S → [X − S, X + S ] o In other words, 68% of scores have a Z-score between -1 an ...
