How these numbers are worked out
Every percentile and rarity figure uses the standard IQ scale: a normal distribution with a mean of 100 and a standard deviation of 15. Real tests have their own norms and margins of error, usually a few points either side, so treat each figure as an approximation rather than a diagnosis.
Above about 160, most major tests stop measuring precisely, so rarity figures there are illustrations of the model. Scores from 55 to 69 have pages too, but a score in that range from a single online test does not mean anything clinical. Only a qualified professional can assess that.
For broader bands, see the IQ classifications guide or try the IQ percentile calculator.
