Answer:
correlational research
Explanation:
In correlational research, there will be two variables, that are used to answer a question or clarify a given issue.
When two variables are related, like time spent studying and the grades achieved by students a psychologist research seeks to analyze the relationships that stem from changes in a variable that impact directly the other:
Lets assume that the higher the time the students they spent reviewing the better the goals they get: in this case, there is a direct relationship.
If for example, we study that the higher time they spent studying the less time they have to work, then we are talking also about an indirect relationship.
