Intention-to-treat analysis of covariance for A1c, planned in advance with a missing-data strategy, anchors this HD560 Unit 7 analysis approach for the Full Basket lottery. Searches like "hd 560 unit 7 assignment example", "hd560 unit 7 sample" and "hd560 unit 7 example" land here.
What a finished HD560 Unit 7 analysis approach looks like
Seven pages organized by question. The primary analysis compares month-six A1c between arms by analysis of covariance, adjusting for baseline A1c and the two stratification variables, and reports the mean difference with a 95 percent confidence interval. All randomized applicants are analyzed in the arm assigned, whether or not they redeemed a card. Missing data get their own page, which proposes multiple imputation using baseline values and redemption, followed by a sensitivity analysis assuming worse outcomes among those missing. A secondary estimate among people who would redeem if offered is labeled as such. Food security is compared as the proportion in low or very low categories. Two prespecified subgroups are tested by interaction terms. The interviews receive a thematic analysis plan and a joint display linking themes to redemption levels.
How a HD560 Unit 7 example is structured
Every analytic choice is tied back to the design. Randomization justifies comparing arms directly; the paper then explains why adjusting for baseline A1c improves precision without introducing bias, and why this is preferred to analyzing change scores. Intention to treat is defended as the answer to the question actually asked, the effect of offering the program. Missing data are treated as a design problem with a stated assumption, not a nuisance to delete. Secondary analyses are few and labeled, so a reader can tell confirmatory results from exploratory ones. Subgroup claims are restricted to interaction tests to prevent overreading. The qualitative strand is integrated deliberately: interviewees are sampled across redemption levels so their accounts can explain the quantitative pattern. Registration of the plan on a public site before the first month-six draw closes the paper.
Primary question, primary model
Analysis of covariance compares month-six A1c between arms, adjusting for baseline A1c and the stratification variables. One estimate and one interval answer the primary question.
Analyzed as randomized
Applicants remain in their assigned arm regardless of redemption. This answers what the clinic can actually decide, whether to offer the program at all.
Missing values, stated assumption
Multiple imputation assumes values are missing at random given recorded data. A sensitivity analysis tests how far results shift if missing participants fared worse.
Exploratory results labeled
The redeemers' estimate and the two subgroup interactions are marked exploratory, so a reader never mistakes them for the confirmatory result.
Interviews sampled to explain
Twenty participants are chosen across high, middle and low redemption. A joint display sets their themes beside the numbers they help explain.
Where marks go in HD560 Unit 7
Analyses picked without reference to the design are the usual shortfall: a paired t-test on a randomized two-arm study, or a regression with ten covariates on a sample of 260. This unit asks for a match between design, data and method, and graders look for the reasoning that connects them. Per-protocol analysis presented as the main result, silently dropping people who never redeemed, is a serious error. Missing data ignored, or handled by deletion without comment, costs marks, as do subgroup findings reported without interaction tests. Plans that promise qualitative analysis but never explain how interviews will be selected or integrated read as unfinished. Strong approaches state the primary analysis precisely, defend intention to treat, handle missing data under a stated assumption, label exploratory work, and commit to the whole plan in advance.

HD560 Unit 7 questions, answered
What does intention to treat mean?
Analyzing everyone in the group they were assigned to, regardless of whether they participated fully. It preserves the balance randomization created and estimates the effect of offering the program. Excluding non-participants breaks that balance, since those who drop out usually differ in important ways from those who stay.
Why adjust for the baseline value instead of analyzing change?
In a randomized design, adjusting for baseline through analysis of covariance generally gives a more precise estimate than comparing change scores, and it handles regression toward the mean appropriately. Change scores are easier to explain, so some plans report them descriptively while using the adjusted model for the main result.
Does a qualitative strand need its own analysis plan?
Yes. Describe how interviewees will be selected, how interviews will be recorded and coded, who will code them, and how themes will be connected to the quantitative results. A sentence promising thematic analysis without those details reads as incomplete in most graduate sections. Two coders working from a shared codebook, with a stated way of settling disagreements, is a common and credible arrangement.
