Is the type I error rate equal to alpha or at most alpha?

WebbThe risk of making a Type I error is the significance level (or alpha) that you choose. That’s a value that you set at the beginning of your study to assess the statistical probability of obtaining your results ( p value ). The significance level is usually set at 0.05 or 5%. WebbWe can see that the probability of a Type I error is α = K ( 100) = 0.05, that is, the probability of rejecting the null hypothesis when the null hypothesis is true is 0.05. We can see the power of a test K ( μ), as well as the probability of a Type II error β ( μ), for each possible value of μ.

A perfect test would have zero false positives and zero false negatives. However, statistical methods are probabilistic, and it cannot be known for certain whether statistical conclusions are correct. Whenever there is uncertainty, there is the possibility of making an error. Considering this nature of statistics science, all statistical hypothesis tests have a probability of making t… WebbTo reduce the probability of committing a type I error, making the alpha value more stringent is quite simple and efficient. To decrease the probability of committing a type II error, which is closely associated with analyses' power, either increasing the test's sample size or relaxing the alpha level could increase the analyses' power.
