Pre-testing. It is vitally important that you pre-test your survey before administering it to your research sample. Pre-testing is the opportunity to see what questions work well, what questions sound strange, what questions can be eliminated and what needs to be added.
Lesson Summary. A pretest-posttest is a quasi-experiment where participants are studied before and after the experimental manipulation. This can be hampered by the practice effect, defined as an influence on performance from previous experience.n a pretest-posttest design, there is only one group and all of them are in the experimental condition. The reason you run a pretest-posttest experiment is to see if your manipulation, the thing you're looking at, has caused a change in the participants.
