The inview has a mean of 100 and a standard deviation of 16, I believe. That would put the CSI (Cognitive Skills Index) at around 126 for the 95th percentile. Is there a reason you need to know the CSI and not just the composite percentile?

15 is a more common standard deviation on IQ tests now a days and a 95th percentile score on an IQ test with a SD of 15 would run about a 125, so a minor difference.
