This researcher studies data from the National Longitudinal Study of Youth and finds that children living with both biological parents had the higher math achievement scores (103) relative to children whoÃs fathers were absent from the home (99) and those whose parents never married (92). Children who lived with both biological parents also had the highest recorded average IQ (103) relative to children from other structures. These associations remained after controlling for motherÃs IQ, parentsÃ education level, and family income.
