If two variables are positively correlated then the correlation value indicates the extent to which the two variables decrease or increase together.

A negative correlation indicates an opposite movement whereby as one variable increase the other decrease. In this study, correlation coefficients are used to compare the relationships between the exams and assignments 1 and 2. The following tables of correlations illustrate the extent of fluctuations of variables.

According to the table above, the correlation coefficient of HI001FinalExam and HI002FinalExam 0.067. Although they are positively correlated, the correlation is slightly weak, being below 0.5.
