Tips for Success:
· It is important to note that research articles are comprised of the following sections:
o Materials and Methods
· Typically, each section you are able to find particular information pertaining to the research question, study design, population, etc.:
§ Here you would find a short summary of the entire paper. It should include goals and objectives, results, and conclusions. This is usually the last part of the paper to be written.
§ It provides background on the topic, review of the literature, focus and purpose of the paper, overview of what is contained in the paper, outcome of interest, and the research question being asked.
§ This section describes what the researcher did and how the researcher did it. Within the methods you will be able to determine the population, where they gathered the participants of the study, data collection methods: interview, questionnaire, focus group, etc., statistical tests used, and study design used.
§ In this section you may also be able to gauge selection bias, information bias, inclusion/exclusion criteria, ethical concerns, and the effect modifier.
§ This section simply provides the results from the statistical analysis (not an interpretation of the results). This may be displayed through graphs or tables. It will indicate whether the results are considered statistically significant or not.
§ The discussion goes over what the results mean and why the results may have ended up as they have. The researcher is able to discuss take home messages, interesting observations, future implications, social change implications, what worked, and what did not work.
In this portion, the reader may be able to gauge bias or ethical concerns that the researcher may have noted
