What a finished MPH-515 Week 5 biostatistics write-up looks like
The write-up reads as a small analysis rather than as an answer sheet. It states the question, names the variables and their types, and justifies the test from those types rather than from habit, since the level of measurement is what decides which procedure applies. Assumptions are checked and reported, including where one is doubtful, because a test run on data that violates its assumptions produces a number that means nothing. Output is included where the section requires it, and the reporting follows a recognized convention. Most importantly the result is given as an effect with a confidence interval alongside any p value, since statistical significance says whether an effect was detected and nothing about whether it matters.
How a MPH-515 Week 5 example is structured
Software and reporting conventions differ, and output style and rounding both carry marks, so work to whatever your section names. The question comes first. Variables are then listed with their measurement level, which is the justification for everything downstream. The test is named and chosen from those levels explicitly. Assumptions follow, each checked and reported rather than assumed. The analysis is run and the output presented in the required form. Results are reported in prose as well as in figures, with the effect size and interval leading and the p value supporting. Interpretation closes the write-up, translating the result into a statement about the population it came from, and any limitation in the data is noted at the point where it bears on that conclusion.
Variables with measurement levels
Each one named as categorical, ordinal or continuous, since the level is what justifies the test and everything downstream rests on it.
Test chosen from the levels
The procedure justified by what the variables are, rather than selected by habit or because it was the one taught most recently.
Assumptions checked and reported
Each one examined and stated, including where it is doubtful, because a test run on data that violates it produces a meaningless number.
Output in the required form
The software results presented as the section specifies, since format and rounding conventions carry marks in these assignments.
Effect size leading
The magnitude with its confidence interval given first and the p value supporting it, since significance and importance are different questions.
Interpretation about the population
What the result says about people rather than about the sample, which is the sentence a non-statistician would actually use.
Where marks go in MPH-515 Week 5
The commonest loss is the p value reported alone: significance declared, no effect size, no interval, and no statement of how large the difference actually was. The second is the test chosen without justification, where a procedure appears with no reference to the measurement levels that would make it appropriate. Beyond those: assumptions never checked, output pasted in with none of the prose reporting the section asked for, rounding inconsistent with the convention named, an interpretation that describes the sample rather than the population, significance treated as proof of importance, and a conclusion drawn well beyond what the design could support. The first and the last of those cost the most.

MPH-515 Week 5 questions, answered
How do I choose the right test?
From the measurement levels of the variables and the number of groups being compared, in that order. Two groups with a continuous outcome, three or more groups, two categorical variables and a paired comparison each point to a different procedure. Writing the levels down before choosing is the habit that prevents most wrong-test errors in this assignment.
What if an assumption is violated?
Report it and say what you did. Options usually include a non-parametric alternative, a transformation, or proceeding with an explicit caveat where the test is robust to that particular violation. What loses marks is running the test and saying nothing, since an instructor checking assumptions will see it and cannot tell whether you looked.
Do I have to include the software output?
Where your section asks for it, yes, and usually in a specified place such as an appendix. Output alone is not a write-up, though, and output omitted where required is an easy loss. The prose reporting is what carries the marks, with the output serving as evidence that the analysis was actually run.
