ADVANTAGES Quasi experimental designs are more frequently used because they are more practical and feasible to conduct research. Since quasi-experimental designs do not need extensive randomization and pre-screening they cut down on both the resources and time required to carry out an experiment. Allows researchers to take advantage of real-world opportunities. The performance of the two groups can then be compared after data is collected to determine if there was a difference in performance of the groups after treatment. Quasi-experiments have lower internal validity than true experiments but they often have higher external validity as they can use real-world interventions instead of artificial laboratory settings.
