Answer:
Answers should include the following points:
1) an advantage of correlational research is that some research questions cannot or should not be addressed by experimental methods for practical or ethical reasons
2) correlational research identifies relationships or associations between variables but cannot be used to infer causal relationships
3) correlations can be useful for making predictions about one variable based on what is known about a different variable
4) correlations can range from - 1.0 to + 1.0
5) values closer to + or - 1.0 indicate stronger relationships while values closer to 0 indicate weak or nonexistent relationships
6) negative values indicate inverse relationships while positive values indicate direct relationships
