Question

Researchers in Taiwan have found that use of birth control was strongly positively correlated to the number of electrical appliances (i.e., toaster, fans, etc.) in the home. What is the best explanation for this result?

Answer 1

Answer:

The number of electrical appliances is inversely proportional to the number of kids that a couple has. It is a variable that is related to the number of electrical appliances and kids.

Explanation:

As the couple does not have children or is not trying fo more of them, the money that would have been used to raise a kid is instead used to buy electrical appliances. We can see that there is a variable, in this case, the income of the family, that connects the number of electrical appliances and the use of birth control.
