What is a key feature of a positive correlation?

A key feature of a positive correlation is that as one variable increases, the other variable also increases. This relationship indicates that there is a direct connection between the two variables being studied. For example, in a scenario where you are evaluating the relationship between hours studied and exam scores, a positive correlation would show that as the number of hours a student studies increases, their exam score tends to rise as well.

In a positive correlation, the variables move in the same direction, which allows researchers to make predictions about one variable based on the changes in another. This is an important concept in research methods because understanding the nature and strength of relationships between variables can help in developing interventions or understanding social phenomena.
