Rather than averaging conflicting results, DBAX 9102's fourth-week analysis explains one disagreement, testing chance, measurement, design and context before judging which studies deserve the weight.

What a finished DBAX 9102 Week 4 disagreement analysis looks like
Four to five pages built around an explanation table. Its first paragraph frames the disagreement as two claims that cannot both be true in the same population. Before anything substantive is proposed, the analysis asks whether the spread exceeds what sampling error and unreliable measures would produce, following Hunter and Schmidt's argument that much apparent inconsistency across studies is statistical artifact. Here it does. The table then lists four candidate explanations, self-selection into participation, differences in outcome measures, length of follow-up and program intensity, with the evidence for and against each. Selection carries most of the gap, since observational comparisons set volunteers against non-volunteers and healthier employees volunteer. Follow-up length remains live: randomized evaluations ran for shorter periods than some observational ones, and the analysis says so rather than dismissing it.
How a DBAX 9102 Week 4 example is structured
The analysis opens on the disagreement itself, stated so precisely that a reader knows which outcome, population and comparison are in dispute. The artifact check comes second, because substantive explanations are wasted on a spread that chance alone could produce. Candidate explanations follow in a fixed order, from the most mechanical to the most substantive, and each is tested against the studies on both sides rather than asserted. Where an explanation predicts something observable, such as larger observational effects in programs with lower participation, the analysis checks whether the prediction holds. A verdict section then states which explanation carries the disagreement and which remain partly open. The close says what the verdict does to the literature's weight: randomized evidence governs the spending question, and observational studies are read for what they can still show, such as who participates.
The dispute in one sentence
Participants spend less; randomized assignment shows little difference. Naming the outcome, the comparison and the population keeps the analysis from treating studies of engagement or wellbeing as part of a spending disagreement they were never in.
Chance and measurement first
Following Hunter and Schmidt, the analysis asks whether the spread is larger than sampling error and unreliable measures would generate. It is, which licenses a substantive explanation. Skipping this check would leave the analysis explaining noise.
Four explanations, each tested
Selection, outcome measure, follow-up and intensity are each set against both sides of the literature. Selection predicts larger observational effects where participation was voluntary and low, and the studies bear that out. Measure differences explain less, since both sides used claims data.
The explanation still open
Follow-up length is not resolved. If program effects take years to appear, short randomized evaluations could miss them. The analysis records this as a live alternative and names the kind of study that would settle it.
What the verdict does to the weight
Randomized evidence governs the spending question from here. Observational studies are not discarded; they still describe who participates and how, which the randomized trials were not designed to explore. Weight moves with the reason for the disagreement.
Where marks go in DBAX 9102 Week 4
The artifact check is where many analyses lose credit quietly. Explaining a disagreement that sampling error could produce, or never asking, reads as unfamiliarity with quantitative synthesis, and doctoral graders notice. The testing section carries the central share: each explanation must face the studies on both sides, and an analysis that simply prefers randomized trials without showing why the observational results diverge has ranked designs, not explained a disagreement. Predictions checked against the literature earn distinct credit. Graders also weigh honesty about the unresolved alternative; declaring the matter closed while follow-up length remains plausible overstates the verdict. The close is read for what it does with the losing side. Averaging the two bodies of evidence, or calling the literature mixed, is the outcome this week exists to prevent.

For this analysis the useful inputs are the Week 4 prompt with its rubric, plus the conflicting studies, cited or named by side. Candidate explanations are tested and a verdict reached in a draft delivered within 24-48h, with the first sample free. Paywalled studies are fine; their citations are enough to build from.
DBAX 9102 Week 4 questions, answered
What if the disagreement cannot be explained?
Then the analysis reports the candidates it tested, what each failed to explain, and the disagreement stands as a finding. An unexplained conflict is useful: it marks a place where the stage's own design might contribute. What loses marks is presenting an untested disagreement as unexplainable, since the reader cannot tell whether explanation failed or was never attempted.
Is a meta-analysis required to do this?
No. A formal meta-analysis pools effect sizes and tests moderators statistically, which is beyond most stage documents. The disagreement analysis borrows its logic instead: check whether the spread exceeds chance, then look for study features that line up with the direction of results. Where a published meta-analysis exists on your topic, cite it and use its moderator tests as evidence in the table.
Does design quality always settle a disagreement?
Often it explains one, which is different. Randomized trials usually carry more weight on questions of effect, but they can be short, small or run in unusual settings, and those features can be the real reason results diverge. Your analysis should show the mechanism by which design produced the gap, as selection does here, rather than invoking a hierarchy of evidence as a verdict.
