I think you are asking how to define correlation, positive or negative, between two variables for which data are available. I'll call the variables x and y. Of course, cto always calculate the correlation coefficient, but you can see the relationship with the graphics. Chart, x-y, which shows a positive trend (positive slope) indicates a positive correlation. Chart, x-y, which shows the negative trend (negative slope) indicates a negative correlation.
