Many areas of psychological research benefit from analyzing studies that were conducted long ago by other researchers, as well as reviewing historical records and case studies. Psychologists want to make statements about cause and effect, but the only way to do that is to conduct an experiment to answer a research question.

All we know from the Illinois data is that drinking was negatively correlated with grade-point average. Uncategorized . critical thinking demands that claims be evaluated with respect to evidence. The model can do this by capitalizing on idiosyncratic relationships between variables that are not likely to be seen in new data. Correlation allows the researcher to investigate naturally occurring variables that may be unethical or impractical to test experimentally. how do correlations help us make predictions psychology.
