The type of research design used was Non equivalent control group pretest-posttest design.

There are many ways to apply research tests, each of them offers different methods and alternatives depending on the needs of the research and the knowledge that you want to obtain.

The pre-test and post-test is a method in which tests are applied prior to the intervention of the investigator and a test after it. In this you want to demonstrate the progress or knowledge acquired by a group.

On the other hand, when two control groups are not equivalent, it refers to the fact that they are not comparable due to some characteristic that differentiates them from the other, for example, profession, age, sex, social origin, among others.
