Author Information
Author(s): Jimmy T. Efird
Primary Institution: Case Western Reserve University
Hypothesis
How does rounding error affect the credibility of epidemiological studies?
Conclusion
Rounding errors can significantly compromise the accuracy and interpretation of epidemiological findings.
Supporting Evidence
- Rounding can simplify data presentation but may mislead if not done carefully.
- Improper rounding can lead to significant errors in epidemiological analyses.
- Guidelines for rounding in epidemiology are not well-established.
Takeaway
Rounding numbers can make them easier to read, but if done incorrectly, it can lead to wrong conclusions in research.
Methodology
The study discusses concepts and techniques for rounding and data truncation in epidemiology, using didactic examples.
Potential Biases
Rounding errors can lead to misinterpretation of results, especially in complex analyses.
Limitations
The study may not account for all sources of rounding inaccuracy and relies on published data that may be imprecise.
