Basic Statistical Significance
Know when results are likely real
Statistical significance tests estimate the chance that observed differences arose by luck, guiding decisions but requiring context and effect size consideration.
- p-value
- alpha
- effect size
- sample size
- confidence
Set Up
Define hypotheses, alpha level, and metrics before testing.
Test
Run appropriate tests; check assumptions like independence.
Interpret
Pair p-values with effect sizes and practical impact; avoid overclaiming.
