Question

Answer 1

Answer:

It can be said that a positive correlation existis between the two variables.

Explanation:

Correlational research looks for an existing relationship between two variables, when there is a relation it can be either positive or negative. Negative correlation is when the variables move in opposite directions, when one of them increases, the other one decreases. A positive correlation existis when both variables move in the same direction, meaning that when one variable increases the other one also increases.

In this case, Dr. Klaus found a positive correlation because he found that when the number of hours of study increased, the performance of the test did also.
