- Chi-square statistic (χ2) with value.
- Degrees of freedom (df).
- P value (exact; report as P = 0.023 or P < 0.001).
- Sample size (total N) and group/category counts.
- Whether Yates’ correction or Fisher’s exact test was used.
- For goodness-of-fit: the expected proportions or counts used.

If the two p-values differ substantially, rely on Fisher's exact test when assumptions are borderline. To perform a "verified" Chi-square analysis in GraphPad
Logical Ordering
: If you are testing for a linear trend (e.g., across age groups or doses), use the Chi-square test for trend (Cochran-Armitage test) only if the categories are ordered and equally spaced. Interpreting and Reporting Results Chi-square statistic (χ2) with value
