A Type 2 error, also known as a false negative, arises when a null hypothesis is incorrectly accepted. WebA type I error appears when the null hypothesis (H 0) of an experiment is true, but still, it is rejected. It is stating something which is not present or a false hit.

Therefore, by setting it lower, it reduces the probability of a type 1 error. "Setting it lower" means you need stronger evidence against the null hypothesis H 0 (via a lower p -value) before you will reject the null.

A Type I error means rejecting the null hypothesis when it’s actually true. It means concluding that results are statistically significant when, in reality, they came about purely by chance or because of unrelated factors.
