Three Roles Told to Disbelieve: A Defense Rehearsal Record for a Tiered Pool Inspection Capstone, Including the Question I Could Not Answer Well
Set-Up
Three classmates took roles for a written rehearsal of my defense of a study set in a fictional county that tiered its pool inspections. One played a methodologist, one a representative of the county's pool operators' association and one a skeptical environmental health director. Each was told to disbelieve everything and to send three written questions, read my written answers, and press one follow-up. I answered within a day and did not look anything up beyond my own draft, since the defense will allow no time for that.
Questions, Answers and Follow-Ups
Table 1
Selected questions with answers and follow-ups, by role
| Role | Question | Short form of my answer | Follow-up pressed | |
|---|---|---|---|
| Methodologist | "Your interval crosses zero. Why is this a finding at all?" | It is a pattern reported with its uncertainty, and the conclusion says so | "Then what would make you abandon it?" | |
| Methodologist | "Isn't the higher-tier drop just regression to the mean?" | A subgroup tiered without regard to violation history showed a similar drop | "How many facilities in that subgroup?" | |
| Methodologist | "Why not use a comparison county?" | None had comparable records; the limitation is stated | None | |
| Operators' representative | "Did anyone ask operators whether more visits helped them or just cost them time?" | No; operators were outside the study's scope | "So the study ignores the people who keep the water safe?" | |
| Operators' representative | "Were pools bumped into the higher tier as punishment?" | Inspectors described moves after bad visits; motive was not studied | None | |
| Operators' representative | "Repeat violations could reflect stricter inspectors, not worse pools." | Inspector changes were not modeled; this is a limitation | None | |
| Director | "If I keep this schedule, what do I lose?" | Lower-tier oversight; no change detected there, but the set was limited | "Limited how?" | |
| Director | "Is a five-point drop worth anything?" | In plain terms, about five fewer repeats per hundred pairs | None | |
| Director | "Who keeps counting after you leave?" | The division analyst, under the handover note | None | |
Answers are shortened here; the full written exchange is in the rehearsal file.
The Question I Could Not Answer Well
The methodologist's follow-up, "Then what would make you abandon it?", exposed a gap. My answer was vague: "a longer series that showed no change." Pressed, I could not say how long a series or how small a change. A better answer names a test in advance: if two further seasons under one pool code give a change in level for the higher tier whose interval sits wholly above -2 percentage points, I would treat the pattern as noise. I have marked this for revision. The conclusion chapter will now state that condition, which also gives the rebuttal in my resized claim a concrete form. Examiners describe a candidate who can say what would change their mind as one who understands the limits of the work (Mullins & Kiley, 2002).
What the Operators' Representative Showed
The operators' follow-up was the most uncomfortable. The study treats operators only as the source of violations, and the person who keeps chlorine levels right every day has no voice in it. I answered that operators were outside the scope, which is true but thin. In the defense I will acknowledge the gap directly and name operator interviews as the most useful next study. Stakeholders who are left out of an evaluation tend to doubt its findings, whatever their quality (Lavis et al., 2003).
What the Director Showed
The director's questions were easiest because the practice brief had already answered them. That suggests the brief did its job. One follow-up, "Limited how?", needed the lower-tier selection explained without jargon. My answer, that only pools visited often enough to compare were counted, worked better than the version in my results chapter.
Changes Before the Defense
Three changes follow: the abandonment condition goes into chapter 5, operator voice becomes the first named direction for further study, and the lower-tier limitation is rewritten in the plain words that worked here. The methodologist's subgroup question also reminded me to give the subgroup size, 41 facilities, every time the regression to the mean check is cited (Morton & Torgerson, 2003).

PUBH 9103 Week 9 instructions, in plain terms
Defense rehearsal assignments ask candidates to practice answering hard questions about their capstone, often with peers in assigned roles. Prompts usually ask for a record of questions, answers and follow-ups, and a reflection on what the rehearsal revealed. Many ask candidates to identify the question they handled worst and how they will improve the answer. Faculty look for rehearsals that were genuinely challenging and that lead to changes. Records showing only easy questions, or reflections that praise the rehearsal without naming a weakness, tend to receive less credit than candid accounts of what went wrong. Prompts may also ask how the rehearsal will change the slides or the opening statement.
How this PUBH 9103 Week 9 example is built
The record opens with the roles, the instruction to disbelieve and the rule of answering without looking anything up. A table gives nine questions, three per role, with shortened answers and the follow-ups pressed. A section on the worst answer quotes the vague response and gives the repaired version with a numeric test for abandoning the finding. Another section treats the operators' challenge as a real gap and names operator interviews as further study. A section on the director's questions notes that the practice brief had already answered them. The last section lists three changes to make before the defense. Answers in the table are shortened, and the full exchange is kept in the rehearsal file for the chair. The abandonment condition is given as a number, not a feeling.
Reading the PUBH 9103 Week 9 rubric
Faculty generally reward rehearsal records for the difficulty of the questions and the honesty of the reflection. Roles covering method, stakeholders and practice earn a solid share. Recording follow-ups shows the rehearsal went beyond scripted questions. The largest credit usually goes to naming the worst answer and repairing it with something concrete, as the abandonment condition does here. Treating a stakeholder's challenge as a real gap, not a misunderstanding, shows maturity. Linking the rehearsal to earlier products, such as the practice brief, demonstrates coherence. A list of specific changes before the defense shows the rehearsal had consequences. A repaired answer that names a specific numeric test shows the candidate can define what would count as failure.
Common PUBH 9103 Week 9 mistakes, and how to avoid them
Ask two or three peers to take roles that match your likely committee and audience, and tell them to doubt everything. Answer in writing without looking things up. Record each follow-up they press. Afterward, pick the answer you are least happy with and write a better one, as specific as you can make it. Note any group your study left out. Then list the changes you will make before the real defense. If you need sharp practice questions for your own study, we can put together a sample rehearsal set. Keep the rehearsal record; your chair may ask to see it.
