LABCRUX GUIDE

Limitations vs errors in lab reports

A limitation constrains interpretation; an error source affects measurement; a mistake is a correctable departure from the intended method or calculation.

Limitations bound the claim

Sample size, measurement range, available controls, and model assumptions can limit generalization even when work was performed correctly.

Random and systematic effects differ

Random variability affects repeatability; systematic effects can bias results in one direction. Both require evidence rather than generic lists.

Mistakes should be corrected

A transcription or arithmetic mistake is not a limitation to preserve in the final report. Correct it and re-audit dependent sections.

Connect each item to impact

Explain which quantity or inference may be affected, expected direction when known, and what evidence supports that assessment.
