p-Value
Six Sigma
p-Value
Probability, assuming the null hypothesis is true, of observing results at least as extreme as those obtained.
Examples
- 01The test of two machines gives a p-value of 0.02, so the difference in average diameter is unlikely to be chance.
- 02In Analyze, the team agrees beforehand that a p-value below 0.05 counts as significant.
- 03The p-value and the size of the effect are both documented, because a small p-value alone does not mean a big difference.
