Think of the horizontal axis as all the different scores one could possibly get, lowest through highest. Percentiles indicate the percentage of scores that fall below a particular value. They tell you where a score stands relative to other scores. For example, a person with an IQ of 120 is at the 91 st percentile, which indicates that their IQ is higher than 91 percent of other scores.SAT scores are calculated by multiplying the z-score by 100 and then adding 500. To convert a z-score on an IQ measure to an IQ score, multiply the z-score by 15 and add 100 to your answer (e.e., z-score= .5. .5 times 15 equals 7.5 plus 100 equals 107.5. Therefore, a z-score of .5 on an IQ measure converts to a T-score of 107.5. Del Siegle, Ph.D.
