Variables, Research Questions, and Hypotheses
The research process begins with an issue or problem of interest to the researcher. Usually the research problem is a statement that asks about the relationships between two or more variables. However, some research problems are purely descriptive and describe one variable at a time. Yet almost all research studies have more than two variables. In this chapter, we discuss variables-including the difference among independent, dependent, and extraneous-research questions, and hypotheses.
