Here are some titles from recent issues of professional journals published by the American Psychological Association.
Below the title are the authors’ names and, on the next line, their institutional affiliation—the university or other institution where the authors worked when they conducted the research.
In a quantitative study, you are assessing participants’ responses on a measure.
For example, participants can endorse their level of agreement on some scale.
In the research questions and null hypotheses portion of the methodology chapter, the research questions should be restated in statistical language.
For example, “Is there a difference in GPA by gender?Procedure The procedure section of the methods chapter is simply how you are going to administer the instruments that you just described to the participants you are going to select.You should walk the reader through the procedure in detail so that they can replicate your steps and your study.Here we consider each of these sections in detail, including what information it contains, how that information is formatted and organized, and tips for writing each section.At the end of this section is a sample APA-style research report that illustrates many of these principles.Data Analysis Plan The data analysis plan is just that — how you are going to analyze the data when you get the data from your participants.It includes the statistical tests you are going to use, the statistical assumptions of these tests, and the justification for the statistical tests.As we have already seen, the authors are listed in an order that reflects their contribution to the research.When multiple authors have made equal contributions to the research, they often list their names alphabetically or in a randomly determined order.” is a t-test type of question, whereas “Is there a relationship between GPA and income level? The important thing to remember is to use the language that foreshadows the data analysis plan.The null hypotheses are just the research questions stated in the null; for example, “There is no difference in GPA by gender,” or “There is no relationship between GPA and income level.” Research Design The next portion of the methods section, chapter three is focused on developing the research design. First, you must decide if you are doing quantitative, qualitative, or mixed methods research.
