Final answer:
A correlational study attempts to determine if changes in one variable produce changes in another variable.
Step-by-step explanation:
A correlational study attempts to determine if changes in one variable produce changes in another variable. It establishes a relationship between two variables but does not determine causation.
For example, a correlational study may find that there is a positive correlation between the amount of studying done and exam scores. This means that as the amount of studying increases, exam scores tend to increase as well. However, it does not prove that studying directly causes higher exam scores. Other factors, such as motivation or intelligence, could also be influencing the relationship.
