Understanding P-values | Definition and Examples - Scribbr
- https://www.scribbr.com/statistics/p-value/
- The p value gets smaller as the test statistic calculated from your data gets further away from the range of test statistics predicted by the null hypothesis. The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null hypoth… See more
