A significant p-value confirms an association exists but does not communicate its strength. Look at Prism's calculated effect sizes:
A statistical test is incomplete without a clear graphic representation. Prism automatically generates a graph paired with your contingency table.

The p-value answers the question: If the null hypothesis were true (meaning no association exists), what is the probability of observing a difference this large or larger by pure chance?
Testing whether a patient's treatment group (Drug A vs. Placebo) is associated with clinical outcome (Recovered vs. Not Recovered). Data structure: A contingency table (e.g., Chi-Square Goodness-of-Fit Test A significant p-value confirms an association exists but
Your data are organized in a , where rows represent one variable (e.g., group membership) and columns represent the other (e.g., outcome categories).

Used for comparing proportions in independent groups.
Input your observed values into the rows (e.g., Treatment, Control) and columns (e.g., Improved, Not Improved).
Even experienced researchers encounter tricky situations with chi‑square analysis. Here is how to handle them:
