Table $$\PageIndex{1}$$ shows negative z-scores, their probability (p-value), and percentage of scores that fall below that probability (p-value). Table $$\PageIndex{2}$$ shows positive z-scores, their probability (p-value), and percentage of scores that fall below that probability (p-value) . If this table is too unwieldy, here is a PDF of a z-score table with only three columns (z-score, p-value, percent) with more than 600 rows of z-scores (instead of Table $$\PageIndex{1}$$).
