"r" correlation coefficient can only be in the range of -1 to +1. If the data obtained closer to +1, indicating that they have a strong positive correlation. On the contrary, if it is closer to -1, to prove that they have a strong negative correlation. There is a number equal to...

To probe these correlations, we ran a factor analysis revealing good and poor relationship factors and an exploratory graph analysis identifying three clusters: positive and negative relationship behaviors and relationship quality. A post-hoc analysis indicated that relationship-quality mediates the effect...
