Two composite populations of different ages get crude and directly adjusted diabetes-related death rates, weights shown, in an NU713 Unit 7 comparison that reconciles the two. Searches like "nu 713 unit 7 assignment example", "nu713 unit 7 sample" and "nu713 unit 7 example" land here.
What a finished NU713 Unit 7 age-adjusted rate comparison looks like
Four pages and two tables, with a script in an appendix. Table one gives each population in five age bands, under 45, 45 to 64, 65 to 74, 75 to 84 and 85 and over, with person-years for 2020 to 2024, deaths with diabetes anywhere on the certificate, and age-specific rates. The east side is higher in every band: 168.3 against 75.6 per 100,000 at 45 to 64, and 446.2 against 249.1 at 65 to 74. Table two applies the 2000 standard weights, collapsed from eleven age groups into the same five bands, and shows each band's contribution. Adjusted rates land at 119.8 and 72.3, with approximate 95 percent intervals of 106.5 to 133.2 and 65.9 to 78.8. The appendix holds about twenty lines of code reproducing both tables.
How a NU713 Unit 7 example is structured
Age structure is shown before any rate, since the whole comparison turns on it: 10.8 percent of east-side residents are 65 or older against 21.8 percent in the west suburbs. Crude rates follow, stated accurately as what each population actually experienced. Age-specific rates come next, and the example points out that they already answer the comparative question, since the east side is higher in all five bands. Adjustment is then framed as a way to summarize those five comparisons in one number, not as the correction of an error. The standard is named with its source and the reason for choosing it: federal and state reports use the 2000 projected population, so the result can sit beside published figures. Collapsing the standard to five bands is disclosed. Interpretation separates uses, and a closing paragraph flags the under-45 band, built on 14 and 8 deaths.
Two age pyramids, side by side
Population shares by band come first. The west suburbs hold twice the east side's proportion of residents 65 and older, which alone is enough to push a crude death rate up whatever the underlying risk.
Crude rates, reported honestly
Rates of 103.1 and 113.3 per 100,000 describe the deaths each place actually recorded. The example keeps them as the right numbers for questions about volume, such as hospice or home health demand.
Higher in every band
East-side rates exceed the west's in all five bands, from 6.7 against 3.5 under 45 to 1,114.3 against 944.0 at 85 and over. Adjustment summarizes that pattern; it does not create it.
The standard, named and collapsed
Weights come from the 2000 US standard population, based on Census Bureau projections, grouped into five bands. The example notes that finer bands would shift both adjusted rates somewhat and says why five were used.
Fourteen deaths under 45
The youngest band rests on 14 east-side and 8 west-side deaths, below the 20 that NCHS treats as the floor for a reliable rate. Its weight is the largest of any band, so its contributions, 4.3 and 2.3 per 100,000, are stated.
Where marks go in NU713 Unit 7
Age adjustment assignments are graded largely on whether the writer understands what the adjusted figure is. A paper calling the adjusted rate the real death rate, or describing adjustment as removing older people, misstates the method and loses more than an arithmetic slip would. Naming the standard population, with its year, earns a specific row in many rubrics; an adjusted rate with no stated standard cannot be compared with anything. The table must let a grader check each weight and each contribution. Interpretation separates stronger papers: crude rates for service volume, adjusted rates for comparing risk, and age-specific rates as the underlying evidence. Common deductions go to intervals omitted, to bands with fewer than 20 deaths reported without comment, and to a conclusion claiming the east side has more deaths, which the counts do not show.

NU713 Unit 7 questions, answered
Why use the 2000 US standard population?
Because NCHS and most state health departments adjust to it, so a rate you compute can be compared with published ones. The standard is a fixed age distribution, not a current population; a different standard changes the adjusted values but should not change conclusions much when age-specific rates point the same way. Always state which standard you used and how many age groups.
When should indirect standardization be used instead?
When the population you are studying has too few events to produce stable age-specific rates, as in a single clinic or a small town. Indirect standardization applies a reference population's age-specific rates to your population's age structure to get an expected count, then compares observed with expected as a standardized mortality ratio. Many sections expect a sentence on why you chose one method.
Do I have to show the age adjustment calculation?
In most sections, yes. A table listing each age band's population, events, rate, standard weight and weighted contribution lets a grader follow every step and spot where an error entered. A spreadsheet or short script in an appendix is a welcome addition. What loses credit is an adjusted rate that appears with no visible route to it.
