Item wording, not file reputation, settles this HLTH 8560E selection memo: three national surveys are compared on a food insecurity question and one is chosen, with its costs stated.

What a finished HLTH 8560E Week 2 dataset selection memo looks like
Two pages or so, organized around a comparison grid and three brief arguments. The grid gives one row per candidate, with columns for the exposure item, the outcome measure, the population covered, the collection mode, and whether design variables ship with the public file. NHIS and BRFSS both ask whether a health professional ever told the respondent they had diabetes, but neither holds a measured blood value, so glycemic control could only be approached through reported testing or medication. NHANES pairs an interview with a physical examination and laboratory work, placing a measured glycated hemoglobin value beside household food security items. The memo chooses NHANES and states the price in the same paragraph: a far smaller sample, coverage of the household population only, and several cycles pooled to reach workable subgroup sizes.
How a HLTH 8560E Week 2 example is structured
Its first paragraph gives the research question a single sentence and names the two variables that question cannot do without, because a selection argued backward from the question reads differently from one argued from convenience. Criteria come next, stated before any file is discussed: the exact wording of the exposure item, whether the outcome is measured or reported, who was eligible, how answers were collected, and whether the documentation supports reuse. Every candidate is then put through the same criteria in the same order, one paragraph apiece, which keeps the three files comparable line for line. The decision follows, naming the chosen file and the specific features that carried it. A final section records what was given up by rejecting the others, chiefly the state-level detail and much larger samples of the telephone survey, and says how that loss narrows later claims.
Criteria fixed before candidates
The memo states what it will judge before naming any file: item wording, measured versus reported outcome, eligibility, mode and documentation. Fixing criteria first keeps the comparison from bending toward a favorite.
A reported diagnosis is not a blood value
Two of the three surveys can identify adults who report a diabetes diagnosis but cannot say how well it is controlled. The memo treats that gap as decisive for this question, not as a minor limitation.
Food security items read closely
The memo quotes the reference period and household framing of the food security questions in the chosen file, and notes where the other surveys use a different set of items or field them only in some states and years.
What the choice gives up
Choosing an examination survey means fewer respondents and no state estimates. That cost is written into the memo, along with the fact that subgroup comparisons will need pooled cycles, and that some of them may not be reportable at all.
Documentation as a criterion
Whether a file ships with its weights, strata and cluster variables, and with a codebook stating who was asked each item, is scored alongside content, since a file that cannot be analyzed correctly is no candidate.
Where marks go in HLTH 8560E Week 2
Graders reading a selection memo want the file chosen for reasons a skeptic could check, and a memo that names the most familiar survey and lists its strengths lands in the lower band. The criteria paragraph is weighed heavily, because criteria written after the choice tend to describe the winner. Argument from item wording draws the analytic credit: quoting the reference period of the food security items, or noting that a reported diagnosis says nothing about control, shows the documentation was read. Doctoral sections expect the tradeoff owned, so choosing the examination survey without mentioning its smaller sample or household-only coverage gives ground. Accuracy about each candidate is checked, and an invented item or a wrong collection mode costs more than a thin paragraph. Citation of the survey documentation itself is expected throughout.

The memo compares candidates on their items and commits to one, and comes back in 24-48h with the first free of charge. Its food insecurity question is illustrative only; the choice in your memo turns on your own variable.
HLTH 8560E Week 2 questions, answered
Is a larger dataset always the better choice?
No. Size helps only if the file measures what the question needs. A very large telephone survey with a reported diagnosis cannot answer a question about control, while a smaller examination survey can. The memo weighs size as one criterion among several, and it says plainly which subgroup comparisons the smaller file will not support, so the tradeoff stays visible to a reader.
How much of the documentation should the memo quote?
Enough to show the deciding items were read: usually the exact wording of the exposure item, its reference period, and the eligibility statement for the outcome measure. Longer excerpts belong in an appendix. Quoting briefly is stronger than paraphrasing, because two surveys can use similar labels for items that ask quite different questions of quite different people.
Can the memo recommend combining two datasets?
Only if they share an identifier or a defensible linkage, which public-use files rarely do. Two separate national surveys cannot be merged person by person. The memo can propose using one file for the main analysis and another to check whether a descriptive pattern looks similar, but it should say that this compares estimates and is not a combined analysis.
