Pre-experimental designs are called such because they often happen before a true experiment is conducted. Often, researchers want to see if their interventions will have an effect on a small group of people before they seek funding and dedicate time to conduct a true experiment.
Why are experimental designs used?
Through accurate and precise empirical measurement and control an experimental design increases a researcher's ability to determine causal relationships and state causal conclusions. Experimental design as a subset of scientific investigation is a popular and widely used research approach.
Why would you use a pretest posttest experimental design?
A pretest posttest design is an experiment where measurements are taken both before and after a treatment. The design means that you are able to see the effects of some type of treatment on a group.
