Text: True or false The correlation coefficient measures any relation between two variables. ["False", "True"] When two variables are correlated, a researcher cannot assume that one variable causes the other. ["False", "True"] Fitting the regression line does not make sense if there is no correlation between the two variables. ["True", "False"] The linear correlation coefficient can never be less than -1. ["False", "True"]
