True or False: The closer r is to 0, the weaker correlation between the variables but the closer r is to -1 or 1, the stronger the correlation between the variables. True or False: In general, if the correlation coefficient for a particular set of data is less than 0.5, then there is significant correlation between the two variables. True or False: If |r| is greater than the critical value, then r is statistically significant, which means it is unlikely to have occurred by chance.

STATISTICS True or False -> If there is no relationship between two variables, then the correlation coefficient is 0.

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"]
