What a finished HLTH 4200 Week 3 rate calculation looks like
Set out as worked items, the calculation presents each result as a short block: the question, the numerator with its source, the denominator with its date, the arithmetic, and one interpretive sentence. Item one finds prevalence on January 1 from round, invented figures labeled illustrative: 20,000 members, 2,000 with a diabetes diagnosis on file, or 10 per 100 members. Item two computes one-year incidence, removing the 2,000 existing cases so the denominator holds only the 18,000 who could still become new cases; 180 new diagnoses give 1 per 100 at risk over the year, with every member assumed to stay enrolled. Item three explains in words why the two figures answer different questions. Last's Dictionary of Epidemiology is credited for separating a proportion, a rate and a ratio, which is why prevalence carries the label proportion.
How a HLTH 4200 Week 3 example is structured
Each item repeats one block pattern, so a reader can check any figure without rereading the rest. Prevalence precedes incidence because the incidence denominator is built by subtracting prevalent cases, and the page shows that subtraction on its own line. Dates are carried in every denominator: prevalence on a named day, incidence over a named year. Units stay consistent, both results per 100 members, so the two figures can sit side by side without conversion. The comparison item comes third and is written without arithmetic, explaining that prevalence describes the burden a plan is carrying while incidence describes how fast new cases are arriving. Closing the page, a brief paragraph lists what the figures cannot show, including undiagnosed diabetes, which no count built from diagnosis records reaches, and the simplifying assumption that nobody left the plan during the year.
One block per figure
Every item is laid out as question, numerator, dated denominator, arithmetic and a sentence of interpretation, so any figure can be checked alone.
Prevalence on a named day
Diagnoses on file on January 1 are divided by all members that day, giving an illustrative 10 per 100.
Existing cases removed
Incidence divides new diagnoses by the 18,000 members who could still become cases, and the subtraction is shown on its own line.
Burden against speed
A prose item explains that prevalence measures what the plan carries and incidence measures how quickly new cases arrive.
What diagnosis records miss
Undiagnosed diabetes and the assumption of unbroken enrollment are named as limits no figure on the page can remove.
Where marks go in HLTH 4200 Week 3
Most of the available points ride on the sentence beneath each figure, not the division above it. Denominator construction earns the largest share: removing existing cases before computing incidence proves the author knows who is still at risk. Dating every figure collects a steady amount, since a rate without its window cannot be verified by anyone. Labeling prevalence a proportion, with Last's dictionary behind the term, answers the precision row most rubrics carry. Units are checked separately and reward the consistent per-100 presentation. The comparison paragraph earns interpretive credit by explaining the difference in plain language. Calculations like this fall short when prevalent cases stay in the incidence denominator, when a figure is printed undated, or when prevalence is called the risk of developing the disease.

HLTH 4200 Week 3 questions, answered
Why is prevalence called a proportion instead of a rate?
Because it compares people with a condition to everyone in the population at one moment, with no time unit attached. Strictly, a rate carries time in its denominator, and Last's Dictionary of Epidemiology keeps the terms apart for that reason. Everyday usage often calls prevalence a rate anyway. The example follows the stricter usage and says so; if your instructor accepts the looser term, the custom version can match it.
Where do the 20,000 members come from?
Nowhere; the figures are made up for the page, and the finished item flags them as illustrative. The figures were chosen so the division is easy to follow and the logic of removing existing cases stays visible. No real health plan or diabetes figure appears on this page. When your section supplies data, a custom calculation works from those values, with every one traced to its source and date.
Does the example say anything about managing diabetes?
Nothing. Its figures describe how common diagnosed diabetes is in an invented plan and how quickly new diagnoses appear. Prevention, testing and treatment sit outside the calculation entirely and are matters for clinicians and diabetes programs. Your prompt may assign a different condition. Whatever it is, the custom sample stays with counting, and decisions about care remain with the people responsible for them.
