The design and analysis plan are written as a student would for the course; the dataset described is illustrative, and your project uses the data your instructor provides.
Design, Data and Analysis Plan: Methods for a Study of Aerobic Activity Guidelines and Self-Rated Health
Design
This study uses a cross-sectional secondary analysis of existing survey data. Jacobsen (2017) describes cross-sectional studies as measuring exposures and outcomes at the same point in time, which allows associations to be estimated but does not establish which came first.
Data Source and Sample
Data come from a de-identified extract of a statewide health survey of adults aged 18 and older, provided for course use. The extract contains 1,200 respondents with complete information on physical activity and self-rated health. Respondents missing either variable were excluded before the extract was created, and no identifying information is included. Because the extract was drawn for teaching rather than with the survey's full sampling weights, results describe this sample rather than producing weighted estimates for the whole state, a distinction the discussion will note.
Variables and Measurement
Aerobic guideline adherence, the independent variable for the first question, was computed from respondents' reported weekly minutes of moderate and vigorous activity, with vigorous minutes counted twice. Respondents with 150 or more moderate-equivalent minutes were coded as meeting the guideline (1) and others as not meeting it (0), following the federal definition (Piercy et al., 2018). Weekly moderate-equivalent minutes were also retained as a continuous variable for the second question.
Self-rated health was measured with the standard five-point question, rated from excellent to poor, a measure that predicts mortality in community studies (Idler & Benyamini, 1997). For analysis, it was dichotomized as good, very good or excellent (1) versus fair or poor (0). Age group, sex and education were included to describe the sample. Age was grouped into young (under 45), middle (45 through 64) and older (65 and up) adults; education was grouped as high school or less, some college and college graduate. These covariates are reported descriptively rather than adjusted for, because the course's research project focuses on bivariate tests.
Analysis Plan
All analyses will be conducted in SPSS with an alpha level of .05. Descriptive statistics, frequencies and percentages for categorical variables and means and standard deviations for continuous variables, will describe the sample. For RQ1, a chi-square test of independence will assess the association between guideline adherence and self-rated health, with the odds ratio and Cramér's V reported to describe its size. For RQ2, mean weekly activity minutes in the two self-rated health groups will be compared with an independent samples t-test; Levene's test will check the equal-variance assumption, and the standardized mean difference, Cohen's d, will be read against the benchmarks of 0.2, 0.5 and 0.8 for small, medium and large effects (Cohen, 1992). Reporting how large a difference is, not only whether it is significant, is what turns an SPSS output into information a program planner can use. Because weekly minutes are likely skewed, results will be checked with a Mann-Whitney U test as a sensitivity analysis.
Ethical Considerations
The analysis uses de-identified secondary data, poses minimal risk and would typically qualify for exemption from full review by an institutional review board. The researcher completed CITI human subjects training in Module/Week 4. Only group-level results will be presented, and no attempt will be made to link records to other data that might identify respondents. The data file will be stored on a password-protected device and deleted at the end of the course.
Limitations of the Methods
Physical activity is self-reported and likely overestimated, and the cross-sectional design cannot show whether activity improves self-rated health or whether healthier people are more active. Dichotomizing self-rated health also discards some information, so the five-category distribution will be reported descriptively as well.

What the HLTH 511 Week 6 instructions ask
The methods part of the HLTH 511 project comes due as Module/Week 6 closes, the week of chapters 15 through 17 of Jacobsen, a review of the statistics chapters and chapter 29, seven presentations, the sixth SPSS assignment and two quizzes, one of them Hypothesis Writing Quiz 4. Worth 110 points, the methods section is one of the heaviest parts of the project. It should describe the study design, data source and sample, how each variable is defined and measured and exactly which statistical tests will answer each research question, along with ethical considerations. Because the whole project, including this section, is limited to 2,500 words, the methods should be precise and complete without unnecessary detail.
How this HLTH 511 Week 6 example is built
The sample methods section is organized under the headings a reader expects. The design paragraph identifies a cross-sectional secondary data analysis. The data and sample paragraph describes a de-identified extract of 1,200 adults from a statewide health survey and the inclusion criteria. Variables are defined one by one: aerobic guideline adherence computed from reported activity, self-rated health dichotomized from a five-point item and age, sex and education as descriptive covariates. The analysis plan pairs each research question with a test, an effect size and the SPSS procedure, and states how missing data will be handled. The ethics paragraph explains why the analysis of de-identified data is low risk and notes the CITI training completed in Module/Week 4.
HLTH 511 Week 6 grading rubric: where the points go
The HLTH 511 methods section is generally graded on whether the design is correctly identified, whether the data source and sample are clearly described, whether every variable in the research questions is defined with its measurement and coding, whether each research question is matched to an appropriate statistical test and whether ethical considerations are addressed. Instructors look for consistency between the introduction's hypotheses and the planned tests, and for awareness of limitations such as self-report bias. Reporting effect sizes alongside significance tests, as the course emphasizes, strengthens the plan. Clear headings and concise writing help the section fit the project's word limit.
HLTH 511 Week 6 help: mistakes that cost points
Begin with the design, naming it precisely, such as cross-sectional, cohort or experimental. Describe where the data came from, who is included and how many. Define each variable: how it was asked or measured, how you coded it and whether it is categorical or continuous, since that determines the test. Then match each research question to a test, stating the alpha level, the effect size you will report and how you will check assumptions. Explain how you will handle missing data and why the study meets ethical standards. Keep it concise, remembering that the whole project cannot exceed 2,500 words, and check that every hypothesis from your introduction has a matching test here.
