In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (a false positive), while a type II error is the failure to reject a false null hypothesis (a false negative).he rate of the type II error is denoted by the Greek letter Î² (beta) and related to the power of a test (which equals 1âÎ²). What we actually call type I or type II error depends directly on the null hypothesis. Negation of the null hypothesis causes type I and type II errors to switch roles.
Alternatively, if the significance level is above the cut-off value, we fail to reject the null hypothesis and cannot accept the alternative hypothesis. You should note that you cannot accept the null hypothesis, but only find evidence against it.n order to undertake hypothesis testing you need to express your research hypothesis as a null and alternative hypothesis. The null hypothesis and alternative hypothesis are statements regarding the differences or effects that occur in the population.
