Some examples of quasi-experimental research design include; the time series, no equivalent control group design, and the counterbalanced design. One famous psychological study was the marshmallow experiment conducted by Walter Mischel at Stanford University in the early 1970s.

Describe three different types of quasi-experimental research designs (nonequivalent groups, pretest-posttest, and interrupted time series) and identify examples of each one. This is a process used to determine the relationship between two variablesin this case, to explain human behavior. The Steps of a Scientific Method for Research.

The teacher and learner went over a list of word pairs that the learner was told to memorize. Each has pros and cons depending on the participants being studied, the hypothesis, and the resources available to conduct the research. Correlational research is considered non-experimental because it focuses on the statistical relationship between two variables but does not include the manipulation of an independent variable.
