WebOct 2, 2015 · In practice one can do that (i.e. computing the normal cumulative distribution function $\Phi$) by converting the raw value to a Z-score (subtract the mean, then divide by std-dev) and then using a lookup table (sometimes called a Z-table) to convert the Z-score to percentile (well, to probability, for percentile multiply that by 100). WebJul 7, 2024 · A percentile is a comparison score between a particular score and the scores of the rest of a group. It shows the percentage of scores that a particular score surpassed.
