The p-value can be perceived as an oracle that judges our results. If the p-value is 0.05 or lower, the result is trumpeted as significant, but if it is higher than 0.05, the result is non-significant and tends to be passed over in silence. So what is the p-value really, and why is 0.05 so important?

Being statistically significant means the results are unlikely to be due to chance. Usually the cutoff for p values is 0.05. That is, if the p value is less than or equal to 0.05, the results are statistically ...

WebbThe appropriate p-value varies. In large samples, rejecting every null-hypothesis with a p-value less than 0.05 to be significant leads to over-rejection. In modern times, datasets often consist of thousands of data points. When that’s the case, p<0.01 won’t cut it either. Over-rejection means we too often will reject a true null-hypothesis.

Webb11 apr. 2024 · The p-value is 0.002, which tells us that the intercept term is statistically different than zero. In practice, we don’t usually care about the p-value for the intercept term.
