WebbThe mean MSAT score and participation rate scatter plot contains at least two clusters. 0 20 40 60 80 100 500 550 600 Participation Rate 2010 Mean Math SAT by State Different clusters may exhibit different forms of association. E.g., the left cluster above shows a moderate negative association, while the right cluster shows no (or a very weak) WebbFor example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables. It is important to note that there may be a non-linear association between two ...
