Case 48 — Correlation in a small observational dataset · source wording exercise
Two variables move together in a small sample. What would a careful discussion acknowledge?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Association does not identify direction or causation, and…” as the discussion anchor; no new event or result is supplied.
Exercise RESEARCH-09200/48: address this question within its stated limits.

Case 48 — Correlation in a small observational dataset · source wording exercise
Clarification for “Correlation in a small observational dataset”: the point beginning “Association does not identify direction or causation, and…” 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: source wording. Retain the source wording beside any paraphrase.

Case 48 — Correlation in a small observational dataset · source wording exercise
Method note for “Correlation in a small observational dataset”: use “Association does not identify direction or causation, and…” 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. Retain the source wording beside any paraphrase.

Case 48 — Correlation in a small observational dataset · source wording exercise
Limit of the answer in “Correlation in a small observational dataset”: “Association does not identify direction or causation, and…” 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: source wording. Retain the source wording beside any paraphrase.

Case 48 — Correlation in a small observational dataset · source wording exercise
Correction note for “Correlation in a small observational dataset”: retain the wording beginning “Association does not identify direction or causation, and…” 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. Retain the source wording beside any paraphrase.

Case 48 — Correlation in a small observational dataset · source wording exercise
Summary draft for “Correlation in a small observational dataset”: the answer addresses “Association does not identify direction or causation, and…”; the related point is “Report sample size, potential confounders…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 48 — Correlation in a small observational dataset · source wording exercise
Reader check for “Correlation in a small observational dataset”: distinguish the discussion point “Association does not identify direction or causation, and…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 49 — Units and scale: prevent a silent comparison error · comparison exercise
Two figures use different units and one axis is logarithmic. How should a comparison be documented?
Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Record the original units and axis transformation, show any conversion…” as the discussion anchor; no new event or result is supplied.

Case 50 — Reading an abstract without skipping the methods · comparison exercise
Clarification for “Reading an abstract without skipping the methods”: the point beginning “Identify population, design, comparator, outcome…” 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: comparison. Make the basis of a comparison explicit before interpreting it.
