The typical probability adopted by researchers to determine whether a result is extreme is 0.05, also known as the significance level or alpha level. This means that if the p-value (the probability of observing a result as extreme or more extreme than the one obtained, assuming the null hypothesis is true) is less than 0.05, the result is considered statistically significant and the null hypothesis is rejected.
