Chi Square Graphpad Verified Direct

Always check the "Expected Values" tab in Prism’s results. If your expected values are extremely low, the Chi-square test may lose its validity, and you should switch to Fisher's Exact Test to maintain a verified statistical approach.

If your sample size is very small (specifically if any "Expected Value" is less than 5), Prism will often recommend looking at the Fisher’s Exact Test result instead of the Chi-square. 5. Visualizing Your Data chi square graphpad verified

Used when you have two categorical variables (e.g., Treatment vs. Placebo and Healed vs. Not Healed) and want to see if they are related. Always check the "Expected Values" tab in Prism’s results
