Table A1 – Unit Normal Table

This table depicts the z-scores and corresponding proportions of the normal distribution. The z-score column lists the z-score to two decimals. The Body column shows the proportion to the larger side of the z-score. The Tail column shows the proportion to the smaller size of the z-score. The Slice column shows the proportion between the mean and the z-score.

Proportions for negative z-scores are the same as for the positive z-scores because the normal distribution is symmetrical.
