Yes. It depends on your research design and specific research questions. In quasi-experimental design, for example, other factors that may affect the outcomes can be controlled through random assignment.

It will arise when researchers interpret the sample data to other persons, other settings, and past or future situations falsely.

How about external validity threats?

Internal validity threats are experimental procedures, treatments or experiences of the participants that threaten the researcher’s ability to correctly interpret the data about the population in an experiment.

Yes researchers should identify potential threats to the internal validity of the experiments and design them for minimizing or eliminating threats.

Thanks to the MEL courses and everyone’s sharing, I’ve learned so much about program evaluation! One puzzling question for me is that as there are so many different models for evaluation, how could the evaluators decide to choose? Hence, may I ask what factors should be taken into consideration when I plan a program evaluation?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
