Strategic Advice: Results from a study can only be generalized to the population from which the sample was taken. Also, keep in mind that positive correlations do not prove causation.

Getting to the Answer: The study was conducted by the American Academy of Pediatrics on children in the United States under three, so the sample is American children under three, which means conclusions can only be drawn about this population. Also, because correlations do not prove causation, the only conclusion that can be drawn is that there is an association between television time and attention disorders for American children under three years old.
