Case 3 — Correlation in a small observational dataset
Two variables move together in a small sample. What would a careful discussion acknowledge?
Exercise RESEARCH-19469/3: address this question within its stated limits.

Case 3 — Correlation in a small observational dataset
Report sample size, potential confounders and measurement uncertainty. Association does not identify direction or causation, and exploratory results need independent evaluation.

Case 3 — Correlation in a small observational dataset
Clarification for “Correlation in a small observational dataset”: the point beginning “Report sample size, potential confounders…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.

Case 3 — Correlation in a small observational dataset
Method note for “Correlation in a small observational dataset”: use “Report sample size, potential confounders…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.

Case 3 — Correlation in a small observational dataset
Correction note for “Correlation in a small observational dataset”: retain the wording beginning “Report sample size, potential confounders…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.

Case 3 — Correlation in a small observational dataset
Limit of the answer in “Correlation in a small observational dataset”: “Report sample size, potential confounders…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.

Case 3 — Correlation in a small observational dataset
Summary draft for “Correlation in a small observational dataset”: the answer addresses “Report sample size, potential confounders…”; the related point is “Association does not identify direction or causation, and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.

Case 4 — Units and scale: prevent a silent comparison error
Record the original units and axis transformation, show any conversion explicitly and retain the original values. Do not compare apparent visual distances across incompatible scales.

Case 4 — Units and scale: prevent a silent comparison error
Two figures use different units and one axis is logarithmic. How should a comparison be documented?
Exercise RESEARCH-19469/4: address this question within its stated limits.

Case 5 — Reading an abstract without skipping the methods
Identify population, design, comparator, outcome definitions and follow-up. Assess whether the conclusion extends beyond the measurements and note what cannot be learned from the abstract alone.
