The probability of a type i error
Webb9 dec. 2024 · The probability of committing the type I error is measured by the significance level (α) of a hypothesis test. The significance level indicates the probability of … Webb12 maj 2011 · To have p-value less than α , a t-value for this test must be to the right of tα. So the probability of rejecting the null hypothesis when it is true is the probability that t > tα, which we saw above is α. In other …

WebbDecreases the probability of a Type I error Decreases the size of the critical region Decreases the probability that the sample will fall into the critical region All of the other options are results of decreasing alpha Previous Next Is This Question Helpful? More Educational Statistics MCQ Questions 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.
WebbHowever, if 100 tests are each conducted at the 5% level and all corresponding null hypotheses are true, the expected number of incorrect rejections (also known as false positives or Type I errors) is 5. If the tests are statistically independent from each other, the probability of at least one incorrect rejection is approximately 99.4%.
