Background The statistical significance α = 0.05 is the cut-off point used to decide whether a hypothesis statistically significant. When p-value less than 0.05, we reject null hypothesis. Although this criterion has been for almost century generate new knowledge, there currently an international discussion about need decrease 0.005. Aim To determine effects that changing p value would have on ...
