NOTE: Use the SAGE Research Methods Online and Cases and the SAGE Research Methods Videos databases to search for scholarly resources on how to apply specific research designs and methods. This can provide help you develop an outline to follow for your own paper. You can get an overall sense of what to do by reviewing the literature of studies that have utilized the same research design. The research design is usually incorporated into the introduction. Describe the methods of analysis to be applied to the data in determining whether or not the hypotheses are true or false.Effectively describe the information and/or data which will be necessary for an adequate testing of the hypotheses and explain how such information and/or data will be obtained, and.Clearly and explicitly specify hypotheses central to the problem,.Review and synthesize previously published literature associated with the research problem,.Identify the research problem clearly and justify its selection, particularly in relation to any valid alternative designs that could have been used,.

The length and complexity of describing research designs in your paper can vary considerably, but any well-developed description will achieve the following: As a consequence, the overall validity of the study will be undermined. Without attending to these design issues beforehand, the overall research problem will not be adequately addressed and any conclusions drawn will run the risk of being weak and unconvincing. With this in mind, a common mistake made by researchers is that they begin their investigations far too early, before they have thought critically about what information is required to address the research problem. In social sciences research, obtaining information relevant to the research problem generally entails specifying the type of evidence needed to test a theory, to evaluate a program, or to accurately describe and assess meaning related to an observable phenomenon. The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible.

Extending the Timeliness of a Topic Idea.

individuals who share a birth year or generational designation). The most commonly studied cohorts are age-related (e.g.

Typically, the shared characteristic is a life event that took place in a particular time period, like birth or high school graduation. In longitudinal studies, researchers collect data from a single set of participants over time.Ī cohort is a group of people who share a particular characteristic.

The only way to guard against cohort effects when investigating the way people change over time is to perform a longitudinal study.

Cohort effects can compromise the results of research that uses cross-sectional methods, which compare two or more groups at a single point in time.

A cohort effect occurs when a research result is impacted by the characteristics of the cohort(s) being studied.

A cohort is a group of people who share common characteristics or experiences, like their year of birth, the region where they were born, or the term they started college.
