I'm having trouble finding the dependent and independent variables of this scenaro:  Average IQ scores for young school children are known to be 100 (SD = 15).  However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy.  Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies.  Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children?
