Sample Size Justification Another important portion of your methods chapter three, is the sample size justification.Sample size justification (or power analysis) is selecting how many participants you need to have in your study.However, I always felt that, of all the sections, the methods section somehow got the shortest shrift in the published papers. Perhaps it is the fact that in many journals of my field, the Materials and Methods section of the articles in the printed journal would be written with a font size that was smaller than the one used for the rest of the article.

” 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.
A well-written methods section helps minimize the external variables that can negatively influence the performance of the experiment, and thereby help flesh out crucial variables if a study is not reproducible.
Negative results are often not reported, but different observations made following a given method/protocol have often led to serendipitous discoveries.
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?During these sessions, students can ask questions about research design, population and sampling, instrumentation, data collection, operationalizing variables, building research questions, planning data analysis, calculating sample size, study limitations, and validity.Research Questions and Null Hypotheses Chapter three should begin with a portion that discusses the research questions and null hypotheses.I have come to believe that writing a good methods section is good scientific citizenship, a cornerstone of sharing empirically-gained knowledge.If the hypothesis investigated and presented by a study is robust, it is often reflected in the reproducibility of study outcomes.Nevertheless, many journals place the methods section after the discussions, likely following the rationale that MOST readers would be interested in seeing the results, reading the discussion and conclusions to extract the juiciest bit from each paper, not bothering to dive into the experimental details described in methods.Or perhaps it is the fact that to a young researcher at the bench as I was, writing up the Materials and Methods section was the easiest: just write down the steps of each experiment from the lab notebook and/or protocol—including the names of reagents, instruments, and any special consumables used, along with the names and locations of the manufacturers of said items; a task in which the most exciting maneuver was to go to the ‘About’ or ‘Contacts’ section of the manufacturers’ web site to figure out a city and state to be put down for the location—an exercise whose point I have never fully understood. I have learnt the tremendous importance of the methods sections when trying to replicate (or re-purpose for a different system) an experiment described in a paper., which unifies the study results into an examination of whether the hypotheses being probed could be accepted or rejected, along with thoughts and speculations from the authors on plausible and reasonable subsequent steps for further investigations in the same or divergent directions.In a few journals, a variant format was allowed, in which experimental results could be discussed in a logical and/or chronological manner in a combined .
