WebMay 12, 2024 · That means that 2.5% of scores in a normal distribution will be higher than this score (100% - 97.50% = 2.50%). In other words, the probability of a raw score being higher than a z-score is p=.025. If do the same thing with (z = -1.96 ), we find that the p-value for z = − 1.96 is .025.
