Mean Cat score versus NPR
Just a question out of statistical curiosity, as it was mentioned on an EP report we have had completed for our daughter. Does anyone know how mean scores correlate to percentile ranks? I know there are defined correlations for each battery, such as 141 equals 99th NPR etc..
But does anyone know how are the combined scores correlated? For instance, a lot of children will not score consistently across all batteries, some will be stronger on VR than NVR or vice versa...so if a child scores highly or lowly across all batteries, how does this correlate to an overall NPR?
