Answer:
False.
Explanation:
The study that Dr. Keyes wants to do is a study that uses two variables (pets and happiness). Dr. Keyes wishes to prove the cause and effect relationship between these two variables that prove that the greater the amount of pets (causes) people have, the greater the happiness of these people (effect). For this reason, we can say that Dr. Keyes is not doing a correlational study.
This is because, although the correlational study wishes to observe the relationship between two variables, this study cannot be applied to cause and effect relationships.
