Hopefully someone with a better understanding of the test will come along and answer your question. I can, however, tell you what our psych told us- the FSIQ is *not* calculated by averaging the four scores. He said many parents get home and call him back saying "wait, I think you did the math wrong" so he always tries to provide parents with that info. Although I have no idea how FSIQ actually is calculated, I can say that the FSIQ your daughter got was likely correct. Hope that's at all helpful!
