What a finished NU 602 Unit 3 standardized rate comparison looks like
The finished comparison is a table with a short argument wrapped around it. Crude figures for both populations open the page and are allowed to make their misleading impression before anything is corrected. The age distribution of each population comes next, which is usually where a reader sees the problem for themselves. Stratum-specific rates are then displayed side by side, and the example pauses on the case where one population is worse in every stratum while looking better overall. Adjustment follows, using a named and cited standard population, with the weighting shown rather than asserted. Adjusted figures are described as comparative devices and not as counts of anything real. The closing states what the adjustment removed, what it could not remove, and which comparison a health department would actually act on.
How a NU 602 Unit 3 example is structured
The example is sequenced to reproduce the discovery rather than to announce it. Crude rates come first because the point of the exercise is that they mislead, and a page opening with adjusted figures has deleted its own argument. The age structures follow, presented as distributions so the imbalance is visible before any technique is applied. Stratum-specific rates are then laid out in parallel columns, which is the step that makes confounding concrete instead of theoretical. The adjustment section names its standard population, cites it, and shows the weighting so a reader could repeat the calculation with a different standard and get a different number. Interpretation comes next and is explicit that adjusted figures exist only for comparison. A short closing names what remains unexplained after age has been accounted for.
Crude figures allowed to mislead first
The comparison opens on the uncorrected numbers, since the whole argument depends on a reader seeing what they appear to show.
Age structures displayed as distributions
Both populations are shown by stratum before any technique is applied, which lets the imbalance become visible without being announced.
Stratum-specific rates set in parallel
Rates within each band sit in adjacent columns, making it plain when one population fares worse everywhere while appearing better in total.
One standard population named and cited
The weighting scheme is identified and referenced, because a different standard produces different adjusted figures from exactly the same input data.
Adjusted numbers labeled as comparative
The example says these figures describe no actual population, which stops a reader quoting one as though it counted real events.
Where marks go in NU 602 Unit 3
Skipping the crude comparison guts this one before it starts. A paper presenting only adjusted figures has removed the contrast it was asked to explain, and a grader cannot see whether the writer understood why adjustment was needed. Reporting an adjusted figure as a real occurrence rate is the second and most persistent error, since those numbers exist only against a chosen standard. Failing to name that standard makes the result unrepeatable. Papers that adjust for age and then announce a cause have gone further than the method allows, because everything not adjusted for is still sitting in the residual difference. The strongest versions name a second confounder they could not address and say which direction it would push.

NU 602 Unit 3 questions, answered
Direct or indirect standardization for this one?
Follow your instructions where they specify. Where the choice is yours, direct standardization suits populations whose stratum-specific rates you actually hold, and indirect suits situations where those rates are unstable or missing and you have expected counts instead. Say which you used and why the data pushed you there, since that sentence often carries more credit than the computation itself.
Which standard population should I weight against?
Use whichever your instructions or your data source name, and if nothing is specified, take a published standard your reader will recognize rather than inventing weights. Cite it. The absolute adjusted values shift when the standard changes, so the number means nothing to anybody who cannot see which population you weighted against and over what age bands.
Does adjustment prove the populations really differ?
Only on the variable you adjusted for. Age standardization removes age as an explanation and leaves every other difference exactly where it was, including smoking, deprivation, occupational exposure and access to diagnosis. A residual gap is a finding worth reporting and it is not a cause, so name the confounders still in play and say how they would likely bend the result.
