Yes. If you let me know what the WISC (specify -IV or -V) index scores are, I can look them up. There are tables for statistical significance of the difference between index scores, and base rates of the magnitude of the difference. Generally, the rule of thumb for clinical significance is both statistical significance at at least the .05 level (I prefer .01), and also a base rate of less than 10%.
Yes, this one.

I think she has a unique profile between index scores so I'm curious if they are statistically rare or significant in testing results.
I can message them to you. Thank you again aeh! I don't know what this forum would do without you.
