Discussion Question 1: Experimental and Non-experimental Design
Research is typically experimental or non-experiment in design. It is important for the investigator to know the difference.
Give an example of a question you would attempt to answer using experimental design and one using non-experimental design. Design two research questions. Write one for an experimental design, and one for a non-experimental design. What makes each research design question different from the other? Review the criteria for each.
Discussion Question 2: Evaluating a Survey
Survey research is as it suggests, asking questions of participants and measuring the results. The survey types are many, but the evaluation of the survey tools is very similar.
