The student's incorporation of source material in their essay was not entirely effective, as they did not explicitly state the use of the Odds Ratio (OR) as a measure of association between the exposure and outcome in the research question. Additionally, the student did not provide a detailed account of their steps for extracting data from the resources, which could have enhanced the clarity of the paper. However, the student did ensure that the source material mostly came from accredited scientific sources. On the other hand, the student did not adequately define technical or subject-specific terms, such as Sleep, Depression, NREM, REM, and GH, which impacted the foundational understanding of the study. Furthermore, the student's use of symbols, equations, and SI units was not consistently appropriate throughout the essay, as evidenced by missing axis labels on a graph. Despite these shortcomings, the student maintained an academic and analytical tone in their writing and avoided oversaturating the essay with technical terms, which improved its readability.
