What a finished MPH-515 Week 3 study design critique looks like
A good critique starts from what the design is capable of. A cross-sectional study cannot establish sequence; a case-control study measures odds and is vulnerable to how controls were chosen; a cohort follows people forward and pays for it in time and loss to follow-up. Naming the design correctly settles half the critique before any flaw is discussed. The rest is bias, and the useful move is directional: saying not merely that selection bias is possible but which way it would move the estimate and therefore whether the reported effect is likely overstated or understated. Confounding is treated the same way, with a specific candidate named rather than a general acknowledgment.
How a MPH-515 Week 3 example is structured
Most sections supply a checklist and mark against it directly, so work to whichever framework yours names. The design is identified first and defended, because papers do not always describe themselves accurately. What that design can establish follows, stated before any criticism, so the critique measures the study against the right standard. The population and sampling come next, with attention to who was eligible and who actually took part. Measurement follows: how exposure and outcome were defined and whether either could be misclassified. Bias is then taken type by type with direction attached. Confounding is handled with named candidates and what was done about them. The critique closes on what the study genuinely supports and what it cannot be used to claim.
Design named and defended
The study type identified from what was actually done, since papers describe themselves loosely and the label decides the whole critique.
What it could establish
The design's capability stated before any fault is found, so the study is measured against the right standard rather than an impossible one.
Who took part
Eligibility and participation examined together, since the gap between who could have been included and who was is where selection problems live.
Measurement and misclassification
How exposure and outcome were defined, and whether either could be wrongly assigned, which is often the quietest weakness in a study.
Bias with a direction
Not that bias is possible but which way it would move the estimate, which is what turns a list of concerns into a critique.
Named confounders
Specific candidates rather than a general acknowledgment, with what the authors did about each one and whether it was enough.
Where marks go in MPH-515 Week 3
The predictable loss is the checklist critique: every category of bias mentioned, none attached to anything in this study, and no direction given for any of them. It looks thorough and demonstrates nothing. The second is the design misidentified, which sends the entire critique off against the wrong standard. Beyond those: limitations copied from the authors' own discussion rather than judged independently, confounding acknowledged with no candidate named, a causal conclusion drawn from a design that cannot support one, no statement anywhere of what the study does support, and the section's own checklist departed from without a reason given. A critique failing the direction test has listed concerns rather than assessed anything.

MPH-515 Week 3 questions, answered
Can I use the limitations the authors listed?
As a starting point, and never as the whole critique. Authors disclose the limitations that are safe to disclose, and a critique reproducing their list has assessed nothing independently. The stronger paper takes one of theirs, says which way it pushes the estimate, and then adds something they did not raise.
How do I work out the direction of a bias?
Ask what would happen to the estimate if the problem were severe. If sicker people were more likely to be recruited, the exposure looks more dangerous than it is and the effect is overstated. Working one concrete scenario through is more convincing than any general statement, and it is what distinguishes a critique from a summary.
Is it acceptable to conclude the study is good?
Yes, and a critique that finds a study broadly sound while naming its real limits is a legitimate result. What loses marks is uniform judgment in either direction, since every design trades something away. The conclusion that matters is what this study supports and what it does not, rather than a verdict on its quality overall.
