The probability of a type 1 error (rejecting a true null hypothesis) can be minimized by picking a smaller level of significance alpha before doing a test (requiring


The type II error (beta) is the probability of inappropriately accepting the null hypothesis (no difference in treatment effect) when a true difference in outcome exists.

In case of type I or type-1 error, the null hypothesis is rejected though it is true whereas type II or type-2 error, the null hypothesis is not rejected even when the alternative hypothesis is true.

The risks of these two errors are inversely related and determined by the level of significance and the power for the test. Why Type 1 errors are more important than Type 2 errors (if you care about evidence) After performing a study, you can correctly conclude there is an effect or not, but you can also incorrectly conclude there is an effect (a false positive, alpha, or Type 1 error) or incorrectly conclude there is no effect (a false negative, beta, or Type 2 error).

Type 1 and type 2 errors

A type 1 error is also known as a false positive and occurs when a researcher incorrectly rejects a true null hypothesis. In statistical hypothesis testing, a type I error is the rejection of a true null hypothesis, while a type II error is the non-rejection of a false null hypothesis. Much of statistical theory revolves around the minimization of one or both of these errors, though the complete elimination of either is a statistical impossibility for non-deterministic algorithms. By selecting a low threshold value and modifying the alpha level, the quality of the hypothesis test can be increased. The knowledge of If type 1 errors are commonly referred to as “false positives”, type 2 errors are referred to as “false negatives”.
