Suppose we use a significance level of 5% for testing our hypothesis. If we wrongly reject the null hypothesis, then …
We are going to make a type I error. The probability of this error is 5%. A type I error is the rejection of a true null hypothesis (also known as a “false positive” finding), while a type II error is failing to reject a false null hypothesis (also known as a “false negative” finding).[1] More simply stated, a type I error is to falsely infer the existence of something that is not there (confirming to common belief with false information), while a type II error is to falsely infer the absence of something present (going against the common belief with false information).
