Which factor would most affect the ACCURACY of the study's measurements?
A study examines fluoride absorption.
Show answer and explanation
Correct answer: D. Failures in the sensitivity of the tests providing results
Accuracy of results is most directly threatened by measurement error / poor test sensitivity.
- A. A potential confounder, but not a direct measurement-accuracy issue.
- B. A confounding variable, not a measurement-validity problem.
- C. An exposure variability issue, not test accuracy.
- D. Correct. Inaccurate/insensitive measurement instruments directly undermine the accuracy (internal validity) of results.
