Begin the report by writing the introduction section. This is an important section because it presents the overall topic, research questions and anticipated results of the research project.
Include a literature review in the introduction. Depending on your field, the length of this review may vary. However, you'll want to include previous studies that have attempted to answer similar research questions. Then, you'll want to either extend work of previous studies, or fill a gap that hasn't been discussed in previous studies.
Write a methods section. After reading this section, your reader should be able to conduct an identical study if they wanted to. You may want to split the methods into subsections. For example, you can have a methods section with the following subsections:
Data
Data Collection
Protocol
Statistical Analysis
Present the results of your research project. If possible, walk the reader through each research question and answer the question using the findings of your study. Results can have some analysis, but typically, the results section is objective. That is, you'll want to present the results and refrain from too much interjection or explanation.
Write the discussion section. This section can be more subjective and should include explanations for the results. Point out any outliers or anomalies in the findings and explain them. Include the significance your findings might have on your field of study.
Conclude with limitations of the study and directions for future research. Including limitations shows the reader that you understand the complexities of your research.
