What a finished DBAX 9102 Week 10 peer challenge looks like
The opening post fills about a page and a half; each of the two replies runs under half a page. The post gives the remainder a single sentence before describing the design: shift-level labor records from a distribution center, comparing overtime hours before and after cross-training across teams trained at different times. It lists the claim the design will support if everything goes right and the two rivals it handles least well, seasonal demand swings and a new scheduling supervisor hired midyear. It closes by asking classmates for a third rival. Platt's strong inference frames the exchange: a design earns its place by excluding alternatives, not by fitting the favored one. Each reply quotes a classmate's design, names an explanation it cannot rule out, and asks what observation would. Sources are listed after each message in APA style.
How a DBAX 9102 Week 10 example is structured
Four moves organize the post. It states the remainder and the design together, because a design can only be challenged against the question it claims to answer. It then states the claim the design will support at best, which sets the ceiling classmates should test. The third move volunteers the design's weak points, a choice that invites harder challenges than a post presenting its design as complete. The fourth asks each classmate which rival they would raise, so replies arrive with a target. Replies follow a different order: the classmate's design quoted in a line, the claim it makes, a rival explanation it cannot exclude with a reason, and a question about the observation that would exclude it. The two replies target different kinds of rival, one about selection and one about timing.
Remainder and design, together
One sentence of remainder, one of design. Stating both lets classmates test fit rather than method in general, which is the question the week sets: could this design, as described, reach this question at all?
The ceiling stated
If everything works, the design shows that overtime fell after cross-training in teams trained earlier than others. It cannot show why. Stating the ceiling keeps the challenge honest on both sides.
Weak points volunteered
Seasonal swings and a new scheduling supervisor are named before anyone raises them. Classmates are then asked for a third, which directs the thread toward alternatives the author has not seen.
Replies that name a rival
One classmate's interview design claims to estimate how much a program reduced errors; the reply asks how interviews separate the program from staff turnover in the same months. Each reply closes by asking for the one observation able to decide the matter.
Two kinds of rival
Selection in one reply, timing in the other. Pressing on the same kind of weakness twice shows a single idea; varying the rival shows the replier reads designs along more than one axis.
Where marks go in DBAX 9102 Week 10
Instructors grade this thread on whether challenges are aimed at fit. A post describing its design without saying what claim it will support offers classmates no target, and it draws less useful replies and a lower mark. Volunteering weak points is rewarded, since it shows the author already reasoning about rival explanations, which is the doctoral habit the week assesses. Replies carry most of the discussion share. A reply suggesting a larger sample or a different method, without naming the rival that sample or method would exclude, is advice rather than challenge. Replies that name a specific rival, explain why the classmate's design cannot rule it out and ask for a deciding observation earn the upper band. Varying the kind of rival across replies is noticed. Praise with no test attached counts toward participation and little else.

Three inputs make this thread: the Week 10 prompt with its rubric, your Week 8 design, and the two classmate posts that need replies. Post and replies return in 24-48h, and the first request is free. Replies answer what classmates actually wrote, so their posts are needed in full; names become placeholders before drafting.
DBAX 9102 Week 10 questions, answered
Is it risky to list my own design's weak points?
Less risky than leaving classmates to find them. A post that names two weak points and asks for a third shows the author understands rival explanations, which is what graders reward this week. It also steers the thread: classmates tend to press where invited. Weak points listed without a plan to address them read differently, so give each one a sentence on how the design will check it.
What makes a rival explanation strong enough to raise?
It must be plausible in the classmate's setting and produce the same pattern the design expects to find. Staff turnover coinciding with a program would produce a before-and-after drop in errors; that is a strong rival. A rival requiring an unlikely coincidence is weak. Platt's argument was that progress comes from designs able to tell such alternatives apart, so a strong rival also suggests an observation that would separate it.
Can a reply propose a better design?
After naming the rival, briefly. The reply's main contribution is showing what the current design cannot exclude and what observation would. A one-sentence suggestion, such as adding a comparison team trained later, can follow. Redesigning a classmate's study in a reply tends to read as presumptuous and moves the discussion from their question to your preferences.
