Hypothesis
This study examines end-digit preference for self-reported height and how it relates with sex, age, educational level or cultural affiliation.
Conclusion
Different preferences for end-digits depending on language and nationality could be observed consistently in all three national health surveys.
Supporting Evidence
- Italian and French nationals preferred end-digits zero and five more than Germans.
- End-digits two, four, six, and eight were more popular among Germans.
- Preferences for end-digits were similar in Swiss and foreign nationals speaking the same language.
Takeaway
People in Switzerland tend to round their height to certain numbers based on their language and nationality, which can lead to inaccurate height reports.
Methodology
Data from three Swiss Health Surveys were analyzed using multivariate logistic regression to assess end-digit preferences.
Potential Biases
Potential bias in self-reported height due to cultural influences on reporting preferences.
Limitations
The study may have selection bias as participants were likely more health-conscious and educated.
Participant Demographics
Participants were aged 15 years and older, with varying educational levels and nationalities.
