Association between hay fever and gender
Statistical test used: (\chi^2) test of independence (2×2 contingency table).
All expected cell counts were (>5), so the standard (\chi^2) approximation is valid.
| Observed no | Observed yes | Expected no | Expected yes |
|---|
| Female | 93 | 64 | 98.7 | 58.3 |
| Male | 51 | 21 | 45.3 | 26.7 |
- (\chi^2 = 2.37)
- degrees of freedom = 1
- p-value = 0.124
With a p-value of 0.124, we fail to reject the null hypothesis at the conventional (\alpha = 0.05) level. There is no statistically significant evidence of an association between gender and self-reported hay fever in this sample.
Below is a bar chart showing the proportion of participants with hay fever in each gender group.
(A difference is visible – ~41% of females vs ~29% of males report hay fever – but the sample size is not large enough for this gap to reach statistical significance.)
Would you like to explore a different variable (e.g. age group or BMI) or run a power calculation to see how many participants would be needed to detect this difference?
