This page holds a finished NR 503 Week 4 data source review example, narrowing from a source's own account of itself to the one field the question depends on. Searches like "nr 503 week 4 assignment example", "nr503 week 4 sample" and "nr 503 week 4 example" land here.
What a finished NR 503 Week 4 data source review looks like
The review reads as a report on one field rather than a tour of a website. It opens with what the source is, then leaves the front page for the technical documentation, because the codebook is where a field's allowed values, its collection moment and its rate of missingness are written down. The chosen field is followed back to the person who fills it: a clinician writing a cause on a death certificate under time pressure, a coder afterwards assigning that wording to a category, a clerk keying an address. Access terms appear too, since a public file and a restricted-use file answer different questions, and so does suppression, which withholds small cells and leaves some groups unanswerable by construction.
How a NR 503 Week 4 example is structured
Some sections assign the source and others let you choose one, which changes only the opening paragraph. Who holds the source and why anybody funds its collection opens the review, briefly. The question then arrives in one line, because it selects the field everything below concerns. The documentation comes next: the codebook or technical notes, cited to the page, with the field's definition and its list of allowed values quoted rather than described. The filling of that field follows, naming who enters it, at what moment in their working day, and from what list they must choose. Missingness is reported as the source reports it. Access terms and any suppression rule come after that. The review closes on two questions the field can answer and one it cannot, each with the reason attached.
The documentation, not the front page
The codebook or technical notes cited to the page, since a field's definition, its allowed values and its missingness are written there and paraphrased everywhere else.
One field, chosen by the question
The review narrows early to the column the question depends on, because a judgment pitched at the level of the whole file gives a reader nothing to act on.
Who fills it, and when
The person entering the value, the moment in their working day they enter it, and the list they must choose from, which together set the ceiling on its accuracy.
Coding as a second author
A cause written in prose and later mapped to a category has passed through two people, and the category is the coder's judgment rather than the writer's words.
What suppression removes
Small cells withheld from publication leave certain groups unanswerable inside this source, which the review states in advance rather than discovering later on.
Where marks go in NR 503 Week 4
Reviewing the source and never reaching the field is where this week is lost: three accurate paragraphs about an agency, and nothing anywhere about the column the question depends on. The next loss is the front page trusted over the documentation, so a definition gets paraphrased from promotional copy while the codebook two clicks away carries the real list of allowed values. Then coding treated as neutral, when a cause written in prose and later mapped onto a category has passed through two people with different jobs and different information. After those: missingness left unreported; suppression rules ignored, so the review promises answers about groups the file will never print; access terms unchecked until the work is nearly finished; and the moment of entry never named, which is the single fact the rest of the judgment turns on.

NR 503 Week 4 questions, answered
Does the source have to be a national one?
Not usually. A state registry, a hospital discharge file or a local vital statistics release can all be reviewed properly, and smaller sources often publish clearer documentation. The requirement is documentation you can read: a source with a published codebook can be judged at field level, while a figure with nothing behind it leaves the review nothing to examine.
What if I cannot get access to the file itself?
Review it from its documentation, which is what most sections expect anyway. Codebooks, technical notes and release schedules stay public even where the records are restricted, and they carry the definitions, the collection method and the missingness rates. Where a restricted-use application would be needed to answer the question, say so, since that is part of what the source can and cannot supply.
How specific does the field have to be?
Specific enough to name. Race and ethnicity as recorded on a certificate, the underlying cause rather than everything listed alongside it, the address at diagnosis rather than the address today. A review that stays at the level of the file describes an institution; one that names a field can say what it will support and where it stops.
