Question

A researcher finds that for every two hours psychology students spend each week studying their abnormal psychology textbook, the students' scores on the course tests improve by an average of 15 points. What can the researcher appropriately conclude from these data?

Answer 1

Answer:

There is a positive correlation between the extra study hours and the increased test scores.    

Explanation:

Positive correlation: It defines a steady relationship between two different variables having the same direction, which means that if the value of one variable increases then the value of the other variable will also increase and vice-versa.

Example: The shorter people will have a small shoe size, whereas the taller people will have a larger shoe size.
