Research studies that do not test specific relationships between variables are called descriptive or qualitative studies.

The first step in summarizing the research design whether in the Introduction or within a research design section is to say why you did what you did.

One strength is that they can be used when experimental research is not possible because the predictor variables cannot be manipulated.

Describe strengths and weaknesses of each of the studies in the articles as well as the sample designs. Of the various observational study designs the descriptive design is the simplest. The type of study design used to answer a particular research question is determined by the nature of question the goal of research and the availability of resources.

Despite these advantages descriptive research has a distinct disadvantage in that although it allows us to get an idea of what is. Descriptive research may identify areas in need of additional research and relationships between variables that require future study.

Propose potential remedies for the areas of weaknesses. Epidemiologic Study Designs Descriptive studies Seeks to measure the frequency of disease andor collect descriptive data on risk factors Analytic studies Tests a causal hypothesis about the etiology of disease Experimental studies Compares for example treatments.
