Small error probability
Using hypothesis testing, you can make decisions about whether your data support or refute your research predictions with null and alternative hypotheses. Hypothesis testing starts with the assumption of no difference between groups or no relationship between variables in the population—this is the null hypothesis. It’s … Visa mer A Type I error means rejecting the null hypothesis when it’s actually true. It means concluding that results are statistically significant … Visa mer A Type II error means not rejecting the null hypothesis when it’s actually false. This is not quite the same as “accepting” the null hypothesis, because hypothesis testing can only tell you whether to reject the null hypothesis. Instead, a … Visa mer For statisticians, a Type I error is usually worse. In practical terms, however, either type of error could be worse depending on your research context. A Type I error means mistakenly going against the main statistical assumption … Visa mer The Type I and Type II error rates influence each other. That’s because the significance level (the Type I error rate) affectsstatistical power, which is inversely related to the Type II error rate. This means there’s an … Visa mer Webb10 mars 2024 · The American Statistician Vol. 52, No. 2 (May, 1998), pp. 119-126 for a clever but straightforward adjustment to improve Wald performance when p is small. …
