In the results, Prism shows "Total observations = N". Verify this matches your raw sum. A mismatch indicates you accidentally included totals as a row or column.
Determines if there is a relationship between two categorical variables (e.g., does treatment type correlate with recovery rate?). Why Use GraphPad Prism for Chi-Square?
Yes, for a 2×2 table, the chi‑square test with one degree of freedom is mathematically equivalent to the two‑sample z‑test for proportions. The chi‑square value equals the square of the z‑score. chi square graphpad verified

Prism will offer the choice between the Chi-square test and Fisher's exact test. For small sample sizes, Fisher's is preferred. You can also select the Yates' continuity correction , though modern statisticians often prefer the uncorrected Chi-square or Fisher's test unless matching a historical protocol.
