Research objectives, questions, and hypotheses bridge the gap between the more abstractly stated research problem and purpose and the study design and plan for data collection and analysis. Objectives, questions, and hypotheses are narrower in focus than the research purpose and often (1) specify only one or two research variables, (2) identify the relationship between the variables, and (3) indicate the population to be studied. A research question is a concise, interrogative statement that is worded in the present tense and includes one or more variables (or concepts).
