Feedback:
Nonexperimental (observational) research includes descriptive researchstudies that summarize the status of phenomenaand correlational studies that examine relationships among variables but involve no intervention or attempt to infer causal connections. Quasi-experiments (trials without randomization) involve an intervention but lack a comparison group or randomization. Longitudinal designs involve data collection at two or more times over an extended period. Experiments (or randomized controlled trials, RCTs) involve an intervention (the researcher manipulates the independent variable by introducing an intervention; control (including the use of a control group that is not given the intervention and represents the comparative counterfactual); and randomization or random assignment (with participants allocated to experimental and control groups at random to make the groups comparable at the outset).
