In statistics, a significance degree is the likelihood of rejecting the null speculation when it’s truly true. In different phrases, it’s the danger of constructing a Sort I error. The importance degree is often set at 0.05, which suggests that there’s a 5% likelihood of rejecting the null speculation when it’s truly true.
Nonetheless, there are occasions when it could be essential to set a unique significance degree. For instance, if the results of constructing a Sort I error are very excessive, then it could be essential to set a extra stringent significance degree, corresponding to 0.01 or 0.001. Conversely, if the results of constructing a Sort II error are very excessive, then it could be essential to set a much less stringent significance degree, corresponding to 0.10 or 0.20.
