Top methods!!

• Case Study : A case study is a qualitative research method. It involves an observation of one individual or a group of individuals over a length of time. The researcher interviews the subject or observes behavior and records the information.

• Experiment: Although this is introduced as a broad kind of research that can be a component of many methods, the term here is used to denote a specific procedure. In science, experiments are the most often-used method of research, and there are principles involved in its employment. One is the presence of a control group. This is an individual, or a group of individuals, that is not manipulated.

• Observational Study: This type of qualitative research can be naturalistic or controlled. It is systematic and carefully recording. The goal of observational research is to identify and describe a variable or even a set of variables. This type of research can be used as a precursor to other types that focus on a single issue.

• Survey:The survey is a “shotgun” approach to research. It depends upon self-reported data, and so can be highly subjective. Because of that, surveys generally involve many subjects.

• Content Analysis: This method of research involves looking at media such as print, television, radio, and others for the repetition of specific words or phrases, or even ideas. It is a quantitative method, employing mathematical data about the words or concepts to study things like stereotyping or certain aspects of culture such as sexuality. This type of research is especially valuable in advertising but can also be used to predict behavior in specific populations.
