In order for psychologists to develop confidence in making these types of decisions it is important to know that the type of design influences the type of conclusion. (Landrum, R. E.). It is important that the psychologist is aware of the different methods of research as well as the limitations of the experiments.
I believe that in order for me as a researcher to build confidence in my abilities, it is important to always understand how to find information on the various research that has already been done, and to study the different methods that have been used in prior experiments. I believe that it is impossible for me to remember every method that is available yet, it is possible to know how to reference research. This should help with confidence building.
