A choropleth of rates per child beats graduated symbols and dot density in the Week 7 rationale for PHLT 8076, because the question concerns burden per resident, not volume or location.

What a finished PHLT 8076 Week 7 thematic map rationale looks like
The rationale pairs one finished map with the argument for its type. The map shades the invented county's census tracts by emergency visit rate per child, in five classes of a single hue. Around it, the paper tests three thematic types against the stated question, where children's asthma burden is heaviest relative to their numbers. Graduated symbols sized by count are rejected because circles grow with population and answer a volume question. Dot density is rejected on two counts: dots placed at random inside tracts suggest home locations that were never mapped, and in sparse tracts a few dots could point toward identifiable households. The choropleth is chosen with a stated weakness, that large rural tracts dominate the eye whatever their values, and the paper explains how outline weight and a population note reduce it.
How a PHLT 8076 Week 7 example is structured
Question, candidates, choice, cost. The question opens the paper in one sentence, phrased as a rate so the argument for normalization is already implicit. Each candidate type then receives a paragraph with the same three parts: what the symbol encodes, what reading it invites, and whether that reading answers the question. Keeping the paragraphs parallel lets a reader compare the types directly. The choice section presents the finished choropleth as the figure and explains its secondary decisions, single-hue sequence, thin tract outlines, and the corridor drawn as a line above the shading. The cost section addresses the large-area bias of choropleth maps honestly and describes the mitigations used. The final paragraph states the one reading the map is designed to produce and two readings it should not be used for.
The question as a rate
Burden relative to the number of children is the stated concern. Phrasing it that way means any symbol that grows with population answers the wrong question.
Circles that measure crowds
Graduated symbols sized by visit counts would swell in the most populous tracts. The rationale keeps this design for a separate question about clinic workload and sets it aside here.
Dots that imply addresses
Dot density scatters points at random within each tract, and readers take them as homes. In thinly settled tracts that impression could expose households, so the design is rejected on privacy grounds as well as accuracy.
A choropleth with its bias named
Shaded tracts suit a rate, but big rural polygons draw attention out of proportion to the children in them. The paper names that distortion and describes lighter outlines and a population note as partial remedies.
One reading intended
The map is built to show where visit rates run highest among the county's tracts. It is not built to show where most visits occur or where any child lives, and the text says so.
Where marks go in PHLT 8076 Week 7
Argued fit between symbol and question is what separates the strong rationales from the rest. Papers that present a finished choropleth and describe it, without showing why the other types were rejected, have produced a map with a caption; the rationale credit depends on the comparison. Each rejection has to name the misreading the rejected type would cause, not just call it less suitable. The privacy argument against dot density earns credit because it shows awareness that a map can disclose as well as mislead. Admitting the choropleth's large-area bias is scored as maturity rather than weakness. Secondary design decisions, hue, outline and overlay, are credited when each is tied to the intended reading. Figure quality matters in a small way, and a missing source line is the commonest avoidable loss on this assignment.

PHLT 8076 Week 7 questions, answered
Can the rationale use two map types together?
Yes, if the question needs both. A choropleth of rates with graduated symbols for counts on top can answer a burden question and a workload question at once, though it asks more of the reader. The sample keeps one type because its question is single. Your rationale can defend a combined design by stating which question each layer answers and showing that the two do not compete visually.
Is dot density ever the right choice for health data?
It can be, for large populations where dots represent many cases and no single dot suggests a household, or where the goal is showing where cases cluster within a region. The sample rejects it for childhood asthma visits in a county with sparse tracts. Your paper can accept it for a different dataset if it explains the dot value and the placement rule.
Should the rationale address a public audience?
It depends on your prompt. Many sections name an intended reader, such as a health department board, and the rationale then explains design choices in plain terms. The sample assumes a technical reader but keeps jargon light. Whatever the audience, the paper states the one reading the map is built for, because that sentence is what every design choice serves.
