Describe the similarities and differences between experiments and nonexperiments or quasi-experiments
What will be an ideal response?
Nonexperimental and quasi-experimental studies are similar to experiments in terms of their general structure. Nonexperiments and quasi-experiments, like experiments, involve comparing groups of scores. However, only in an experiment does a researcher create treatment conditions by manipulating an independent variable. Although nonexperiments and quasi-experiments resemble experiments, they contain a confounding variable or other threat to internal validity that is an integral part of the design. Therefore, these studies cannot establish unambiguous cause and effect relationships.
