110modeled norms. This is considered an R‐PAS limitation so that new normative data collection isbeginning.In creating norms for the Rorschach, a significant challenge is contending with nonnormal,skewed, count distributions often with low base rates and many zero values. To dealwith this, R‐PAS used percentile‐based transformations to generate standard scores in twosteps. The first step is to identify the percentile rank of all scores. Thus, percentilescorresponding to each raw score were computed. If 21 percent of the people, have a score of.05 or less for FQ‐% (X‐%), it is assigned a percentile score of 21. If a score spans multiplepercentiles, the median of the interval is assigned. For example, 55% of people have Texture =0, so the percentile score equivalent is 27.5.The second step converts the percentile score to a Standard Score equivalent.Consequently, each score is represented on a scale characterized by Median and M = 100, SD =15. Returning to the Texture example, the 27.5 percentile corresponds to a standard score of91. It is important to note that research data indicates that T = 0 is very common, occurring inmore than 50% of the people. Although it may not be optimal, it cannot be thought to beproblematic or pathological. Rather the variable may be insensitive and tend to missoccurrences of adequate interest in contact comfort and closeness. Such a change ininterpretation is an example of incorporating research findings in R‐PAS, aligning interpretationwith research findings, and recognizing problems in norms, as discussed in the current andprevious sections of this paper.As another example, let’s return to MC. MC is the sum of Human Movement and theWeighted Sum of Color, what was known as “Experience Actual” or EA in the CS. Changing thesymbol to MC makes the calculated variable more transparent and it derivation easier toremember for new learners, part of the R‐PAS effort to make the system easier to learn and touse, again at least in English. In any event, an 11 for MC is a high score, placing the person at astandard score of 115, because it resides at the 84 th percentile. Alternatively, and FQ‐% (X‐% inthe CS) calculated with the new, extensive R‐PAS FQ tables, of 3% is a low score, at the 16 thpercentile corresponding to a standard score of 84.
