Dr. Klaus conducted research in psychology, which established that the number of hours of study before a test is directly proportional to performance in the test. In the context of correlational research, it can be said that exists between the two variables.

positive correlation

Explanation:

Correlation can be defined as a study in which there is a measure of how strongly two or pmore variables are related to each other.

It measures how strongly variables are actually related to each other.

Positive Correlation is then defined as a positive correlation. This simply means that high values of one variable are associated with high values of the other. Or if you like, the variables increase together.

Under positive correlation, variables increase together.

Here the number of hours of study before a test is directly proportional to performance in the test. Hence, the higher the time, the higher the performance in the test.
