A statistical test is incomplete without a clear graphic representation. Prism automatically generates a graph paired with your contingency table.
Prism will ask you to choose among several effect‑size calculations: odds ratio (for case‑control studies), relative risk (for prospective studies), or the difference between proportions. In addition, Prism suggests using Fisher’s exact test for the P value when the table is 2×2.

For , Prism supports any number of rows and columns.
When someone says a result is "Chi-square GraphPad verified," it means they have run a Chi-square test (usually the Chi-square test of independence or goodness-of-fit) using GraphPad Prism software to confirm that the data supports their hypothesis. GraphPad Prism is widely used in biological and medical research because it guides users through the assumptions of the test and presents the results clearly. A statistical test is incomplete without a clear

Chi-square tests must be performed on raw counts. Prism will give an error or incorrect results if you enter percentages or means. In addition, Prism suggests using Fisher’s exact test
The typical sentence structure for reporting a Chi-square test is:
Value: The magnitude of the difference between your observed data and expected data. Higher values point toward a significant difference. Calculated as . For a standard
