Types of Research Design.pptxBusiness research methods

An exploratory design is conducted about a research problem when there are few or no earlier studies to refer to or rely upon to predict an outcome.

Purpose of Exploratory Research Design
The focus is on gaining insights and familiarity for later investigation or undertaken when research problems are in a preliminary stage of investigation
Familiarity with basic details, settings, and concerns.
Well grounded picture of the situation being developed.
Generation of new ideas and assumptions.
Development of tentative theories or hypotheses.
Determination about whether a study is feasible in the future.
Issues get refined for more systematic investigation and formulation of new research questions.
Direction for future research and techniques get developed.

Methods
Secondary analysis/Review of literature.
Expert opinion/experience survey.
Focus group discussion.
Comprehensive case method

4. Conclusive research Design Conclusive research aims to verify insights and to aid decision makers in selecting a specific course of action. Conclusive research is sometimes called confirmatory research, as it is used to "confirm" a hypothesis Types : Descriptive Research. Experimental research . Descriptive Research Types : cross sectional studies. Longitudinal studies Experimental research design Is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables Types : Pre experimental design. Quasi-experimental design True experimental design Statistical experimental design

5. Quasi-experimental design No random assignment of participants. May or May not have a control group. May or may not have a control over manipulation of variable.

6. True experimental design For an experiment to be classed as a true experimental design, it must fit all of the following criteria. The sample groups must be assigned randomly. There must be a viable control group. The tested subjects must be randomly assigned to either control or experimental groups

7. Statistical experimental design The term Statistical experimental design refers to a plan for assigning experimental units to treatment conditions. A good experimental design serves three purposes Causation. It allows the experimenter to make causal inferences about the relationship between independent variables and a dependent variable Control. It allows the experimenter to rule out alternative explanations due to the confounding effects of extraneous variables (i.e., variables other than the independent variables ). Variability. It reduces variability within treatment conditions, which makes it easier to detect differences in treatment outcomes
