Case studies emphasize detailed contextual analysis of a limited number of events or conditions and their relationships. Researchers have used the case study research method for many years across a variety of disciplines.

Video: Correlational Research: Definition, Purpose & Examples This lesson explores, with the help of two examples, the basic idea of what a correlation is, the general purpose of using correlational research, and how a researcher might use it in a study.

Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.

Qualitative research methods today are a diverse set, encompassing approaches such as empirical phenomenology, grounded theory, ethnography, protocol analysis and dis- course analysis.

The word experimental research has a range of definitions. In the strict sense, experimental research is what we call a true experiment. This is an experiment where the researcher manipulates one variable, and control/randomizes the rest of the variables.

As it stands both the nomothetic and idiographic approach, both make valid contributions to research. However the relative value of each approach depends upon the purpose of the research. The idiographic approach is better suited to description, while idiographic is suited to predictions.

Quasi-experimental research eliminates the directionality problem because it involves the manipulation of the independent variable. It does not eliminate the problem of confounding variables, however, because it does not involve random assignment to conditions.

A qualitative research interview seeks to cover both a factual and a meaning level, though it is usually more difficult to interview on a meaning level. (Kvale,1996)

Nomothetic research is about attempting to establish general laws and generalisations. The focus of the nomothetic approach is to obtain objective knowledge through scientific methods. Hence quantitive methods of investigation are used, to try and produce statistically significant results.

Observational research (or field research) is a type of correlational (i.e., non-experimental) research in which a researcher observes ongoing behavior. There are a variety of types of observational research, each of which has both strengths and weaknesses.

Controlled observations are usually overt as the researcher explains the research aim to the group, so the participants know they are being observed. Controlled observations are also usually non-participant as the researcher avoids any direct contact with the group, keeping a distance (e.g. observing behind a two-way mirror). Strengths. 1.

A questionnaire is a research instrument consisting of a series of questions for the purpose of gathering information from respondents. Questionnaires can be thought of as a kind of written interview. They can be carried out face to face, by telephone, computer or post.

The Delphi method can help to uncover data in these research directions. The Delphi method is an iterative process used to collect and distill the judgments of experts us- ing a series of questionnaires interspersed with feedback.
