    the research. Your hypothesis might be that there is a positive correlation (for example‚ the number of hours of study & your midterm exam scores)‚ or a negative correlation (for example‚ your levels of stress & your exam scores). A perfect correlation would be an r = +1.0 & -1.0‚ while no correlation would be r = 0. Perfect correlations would almost never occur; expect to see correlations much less than + or - 1.0. Although correlation can’t prove a causal relationship‚ it can be used for prediction
