One Sample t-test: Definition, Formula, and Example - Statology

WebbIncreasing the sample size can increase the Power of the Test. The following are examples of Type I and Type II errors. Example 9.5. Suppose the null hypothesis, H 0, is: Frank's rock climbing equipment is safe. Type I error: Frank thinks that his rock climbing equipment may not be safe when, in fact, it really is safe. WebbYou can avoid making a Type II error, and increase the power of the test to uncover a difference when there really is one, mainly by increasing the sample size. To calculate the required sample size, you must decide beforehand on: the required probability α of a Type I error, i.e. the required significance level (two-sided); the required ...
