Verifying Chi Square Test Results using GraphPad: A Step-by-Step Guide
A chi-square test of independence was performed in GraphPad Prism (version X). The association between treatment (Drug A vs. Placebo) and survival outcome (survived/died) was significant, χ²(1, N = 100) = 6.45, p = 0.011. No expected cell counts were <5. chi square graphpad verified
- Chi-square: Check the box.
- Fisher's exact test: Prism automatically recommends this for 2x2 tables. Always verify – if any expected count is <5, rely on Fisher’s exact test, not Pearson’s Chi-Square.
- Yates' continuity correction: Prism allows this for 2x2 tables. Verification note: Yates' correction is conservative. Many statisticians now advise against it. GraphPad’s official recommendation is to use Fisher’s exact test instead for small samples.
: Reject the null hypothesis. There is a statistically significant association between your variables. Verifying Chi Square Test Results using GraphPad: A
