Case Series and Case Reports: These consist either of collections of reports on the treatment of individual patients with the same condition, or of reports on a single patient. Case series/reports are used to illustrate an aspect of a condition, the treatment or the adverse reaction to treatment.

Case control studies are observational because no intervention is attempted and no attempt is made to alter the course of the disease. The goal is to retrospectively determine the exposure to the risk factor of interest from each of the two groups of individuals: cases and controls.

Correlational Analysis Not all research uses an experimental design. Correlational analysis examines a number of instances and asserts, based on various initial assumptions (which we will examine in the section on Statistics: Correlation), that there is a co-relationship between variables.

Cross-sectional research studies are based on observations that take place in different groups at one time. This means there is no experimental procedure, so no variables are manipulated by the researcher.

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.

I agree that random assignment is an effective sampling technique, however I think that the level of effectiveness can depend on the experiment and the experimental method being used.

What research does for an editorial: Makes for a stronger case. One of the main goals for an editorial writer is to persuade public opinion. The more research done, the more credible the writer’s column is. Allows the writer to better understand the topic, thus making it easier for the reader to read.

Thus quasi-experimental research is research that resembles experimental research but is not true experimental research. Although the independent variable is manipulated, participants are not randomly assigned to conditions or orders of conditions (Cook & Campbell, 1979) [1].

Here it is convenient to follow the terminology used by the Cochrane Collaboration, and use "meta-analysis" to refer to statistical methods of combining evidence, leaving other aspects of 'research synthesis' or 'evidence synthesis', such as combining information from qualitative studies, for the more general context of systematic reviews.

Quantitative research is rooted in numerical approaches. The emphasis is on objectivity and the use of statistics or data gathered through polls, questionnaires or surveys.

Randomized controlled trials are the gold standard of scientific testing for new medical interventions. They have become the standard that must be met by pharmaceutical companies in the process of working out what level of efficacy and safety can be achieved by an experimental drug.

This guide will help you identify the basic differences between a literature review and a systematic review. It’s common to confuse systematic and literature reviews because both are used to provide a summary of the existent literature or research on a specific topic. Regardless of this ...

Types of experiments By definition, all experiments involve manipulation of one or more independent variables, and observing the effect on some outcome (dependent variable). Experiments can be done in the field or in a laboratory.

Systematic reviews formulate research questions that are broad or narrow in scope, and identify and synthesize studies that directly relate to the systematic review question. They are designed to provide a complete, exhaustive summary of current evidence relevant to a research question.
