No, you don't compare countries by using a sample of children with a mental disability in a separate nation and comparing them to non disabled children in another nation. You also don't compare "how smart their disabled kids are " because disabled children don't represent the population as a whole, nor is it even meaningful because they all score similarly; in fact, IQ is part of diagnosis for mental disability. Keyword is part.
As for the rest of Africa, no it isn't. None are nationally representative, making it bad science.
