P-Value Calculator
The p-value is the probability of observing results as extreme as your data, assuming the null hypothesis is true. A small p-value (typically < 0.05) suggests the results are unlikely to be due to chance, providing evidence against the null hypothesis.

Pro Tip
A p-value < 0.05 does not mean the effect is large or practically important. A study with 10,000 participants can find statistically significant but trivially small effects. Always report effect sizes alongside p-values.
