This is an example of a single-blind study since the participants do not know which group they have been assigned to, but the researchers do know. In a double-blind study, neither the participants nor the researchers know who is in the experimental or control group. Correlational studies examine the relationship between variables and do not involve manipulation of variables. Field research involves observing behavior in natural settings rather than in a laboratory.
