What a finished NU 602 Unit 1 rate calculation worksheet looks like
The finished worksheet shows arithmetic rather than talking about it. Each item opens with the question in words, then the formula written out, then the substitution with units attached, then a result expressed per stated population over a stated period. Denominators carry the visible labor: the worksheet says who was at risk, who was taken out because they already had the condition, and how people entering partway through were credited in person-time. One sentence of interpretation follows every result, turning the figure into something a clinician would say out loud. Where two measures come from a single table, the worksheet states which question each of them is fit to answer. Numbers are labeled illustrative and chosen so the working stays legible rather than impressive.
How a NU 602 Unit 1 example is structured
The example is laid out so a grader follows each step without rebuilding it. Every item occupies a block with the same five parts, question through interpretation, which makes an error locatable instead of merely wrong. Definitions arrive before any division, because incidence and prevalence part company at the denominator and a worksheet that starts computing has skipped the only decision that mattered. Person-time gets an item of its own, with each contributor's observation window displayed, since that is the calculation drafts abbreviate into a guess. Items run from plain counts toward measures carrying a time dimension, so the reasoning accumulates rather than jumping. The final block sets two results from identical data beside each other and says what each one supports, which is where a quantitative page earns its interpretation credit.
Denominator settled before anything is divided
Each item names who was at risk and who was removed, because a rate is only as defensible as the population sitting underneath it.
Formula, substitution and result kept apart
Splitting the three steps lets a reader locate an arithmetic slip precisely, rather than crossing out an entire item and moving on.
Person-time shown for each contributor
Individuals who enter or leave partway through receive their actual observation window, which is the step most drafts replace with a round estimate.
Units carried through every line
Cases per population per period travel alongside the figure, since a rate reported bare cannot be compared against anything published anywhere.
One sentence of meaning per result
Every figure closes with a reading a clinician could speak aloud, because an uninterpreted number is arithmetic and not yet epidemiology.
Where marks go in NU 602 Unit 1
Arithmetic is gradeable in a way prose never is, and denominators are where most of it goes wrong. Dividing by an entire population when the question concerned people genuinely at risk produces a figure that is simply incorrect, and discussion piled on top does not rescue the item. Leaving existing cases inside an incidence denominator is that same error in different clothing. Missing time is the next loss, since a rate with no period attached cannot be set against anything and reads as a misunderstanding of the measure. Rounding early distorts small denominators badly. Worksheets that reach correct figures and stop there give up the interpretation credit, which most rubrics treat as its own criterion.

NU 602 Unit 1 questions, answered
Does the working have to be shown?
Assume yes unless your instructions say otherwise. A bare answer earns credit only if it happens to be right, while displayed working lets an instructor award partial credit when one substitution slipped and everything else was sound. It also proves you chose the denominator deliberately, which is the reasoning the item exists to test rather than your ability to operate a calculator.
How do I decide between incidence and prevalence?
Read what the question wants to know. If it asks how much new disease appeared over a stretch of time, that is incidence and only people capable of becoming cases belong underneath it. If it asks how much disease exists right now, that is prevalence and current cases stay in. Wording like new cases, developed or occurred during is usually the giveaway.
Can the worksheet use numbers I invented?
Where your section supplies a table, use that one. Where it does not, constructed figures are normal and expected, so keep them plausible, label them clearly as illustrative and choose values that make the steps visible rather than values that divide suspiciously well. What you must never do is present constructed figures as surveillance output from a real population.
