Inventing Research Problems
Research design has the purpose of obtaining answers to research questions and controlling variance.
1) Explain what this statement means.
2) How does a research design control variance?
3) Why should a factorial design control more variance than a one-way design?
4) How does a design that uses matched participants or repeated measures of the same participants control variance?
5) What is the relation between the research questions and hypotheses and a research design?
6) Invent a research problem to illustrate your answers to these questions.
