| Because of the correlational design, however, the cause and effect of this relationship is unknown. |
| To examine and simplify interpretation of correlational matrices, investigators commonly use factor analytic procedures. |
| When inferential statistics are presented, then the study is either correlational or causal. |
| With Sedgwick's Cambrian based mainly on lithologic criteria, the presence of Silurian fauna created correlational difficulties. |
| Since this was a correlational study, no causations can be assumed regarding self-esteem. |
| In fact, descriptive research is very valuable in identifying potential areas for further correlational or causal investigation. |
