T/F:With regard to correlations, tests can be either directional or nondirectional.

T/F:A significant correlation indicates a meaningful relationship.

T/F:If two variables are significantly correlated, this means that one variable causes the other.

T/F:The correlation coefficient can only be used for one-tailed tests.

T/F:Correlations can be used to examine the differences between groups.

T/F:A single correlation can be computed in order to determine the relationship between three variables.
