tables to prevent overestimating significance in small samples, most modern statisticians (and the GraphPad documentation) suggest leaving it off unless you have a specific requirement, as it can be overly conservative. 4. Interpreting Verified Results
Use the tool to add your P-value or significance asterisks (e.g., *** for ) directly onto the graph for publication.
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
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.
To get a verified result, you must set up your data table correctly. Prism is rigid about table types—choosing the wrong one will prevent the analysis from running.
, the association between your variables is statistically significant. You can reject the null hypothesis that the variables are independent. Chi-square Metric ( χ2chi squared
Select from the list of contingency table analyses. In the options dialog, ensure Chi-square is selected. The "Yates' Continuity Correction" Debate
For a contingency table, this is calculated as should always be 1.
