Question

question 45 (1.5 points) listen which research question must be tested by using a correlational strategy? do parents who frequently hit their children have more aggressive children? does reinforcement promote learning? do children with autism spectrum disorders respond best to a certain medication? does providing snacks help children focus better on a laboratory task?

Explanation:

To determine which research question must use a correlational strategy, we analyze each option:

• "Does reinforcement promote learning?" and "Does providing snacks help children focus better on a laboratory task?" and "Do children with autism spectrum disorders respond best to a certain medication?" can be tested with experimental designs (manipulating variables like reinforcement, snacks, or medication to see effects).
• "Do parents who frequently hit their children have more aggressive children?" involves examining the relationship between two variables (parent hitting frequency and child aggression) without manipulating either, which is the essence of a correlational strategy. Experimental manipulation here would be unethical (can't assign parents to hit children), so correlational is the only feasible approach.

Answer:

A. Do parents who frequently hit their children have more aggressive children?
