The scatter diagram shows the relationship between two variables. If the scores cluster in a pattern that extends from the lower-left to the top-right corner, it indicates a positive correlation between the variables, as one variable increases, so does the other. This is depicted in data set A. In contrast, if the scores cluster in a pattern that extends from the upper-left to the lower-right corner, it indicates a negative correlation between the variables, as one variable increases, the other decreases. This is depicted in data set B. Therefore, the best choice is B, positive correlation; negative correlation.
