Answer to Question 1
A
Feedback:
Hypotheses state researchers' deductively derived expectations about relationships between study variables. To answer research questions and test hypotheses, researchers analyze their data in an orderly fashion. When quantitative research is performed within the context of a theoretical framework, the findings may have broader significance and utility. Even when the research question is not embedded in a theory, researchers should have a conceptual definition rationale and a clear vision of the concepts under study.
Answer to Question 2
B
Feedback:
Qualitative research often is rooted in research traditions that originate in other disciplines. Three such traditions are grounded theory, phenomenology, and ethnography.
Grounded theory seeks to describe and understand key social psychological processes that occur in a social setting. Phenomenology focuses on the lived experiences of humans and is an approach to gaining insight into what the life experiences of people are like and what they mean.
Ethnography provides a framework for studying the meanings, patterns, and lifeways of a culture in a holistic fashion. A key distinction in quantitative studies is between experimental research, in which researchers actively intervene to test an intervention or therapy, and nonexperimental (or observational) research, in which researchers make observations of existing phenomena without intervening.
