Chi Square Graphpad Verified Info

Let’s walk through a real-world scenario to cement your knowledge.

Scenario: A researcher wants to know if blood type (A, B, AB, O) is associated with COVID-19 severity (Mild, Severe). Data from 200 patients.

Step 1 – Table in paper: | Blood Type | Mild | Severe | | :--- | :--- | :--- | | A | 50 | 20 | | B | 30 | 25 | | AB | 10 | 5 | | O | 40 | 20 |

Step 2 – Enter into GraphPad:

Step 3 – Run analysis:

Step 4 – Verify output:

Step 5 – Graph:

Verification note: Because no expected cell was <5, we are confident reporting the Pearson Chi-Square.

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.

| | Survived | Died |
|----------|----------|------|
| Drug A | 42 | 8 |
| Placebo | 30 | 20 | chi square graphpad verified

Use GraphPad Prism to run chi-square tests and report results clearly and reproducibly. Below is a concise, publication-ready template with steps, output interpretation, and example wording.

Prism generates a results sheet with several key sections:
