When do you reject the null hypothesis?

When do you reject the null hypothesis?

The null hypothesis can only be rejected if the associated p-value does not exceed the significance level or the t-value does not exceed the critical value.

When is the Levene test significant?

Carrying out the Levene test in an ANOVA The important column is the “significance”. Since the null hypothesis should not be rejected if the variances are equal, the significance should therefore be greater than 0.05. This is the case in this example. Line) the significance of the Levene test is 0.955.

What does asymptotic significance mean?

Asymptotically. The level of significance based on the asymptotic distribution of a test statistic. Usually, a value below 0.05 is considered significant. Asymptotic significance is based on the assumption that the dataset is large.

When is the one-sided and two-sided t test?

The basic principle of one-sided tests and two-sided tests The null hypothesis does not assume any differences or direction in mean value comparisons and regression models is therefore the decisive reason for being able to test one-sided. If there is no presumption of effectiveness, only two-sided testing remains.

When is the two-sided hypothesis test?

A hypothesis test is called two-sided if the alternative hypothesis H1 includes deviations from the null hypothesis H0 on both sides, i.e. H0: p = p0; H1: pp0⇔p ≠ p0. The decision rule has the form “Assumption of H0 if c1≤X≤c2” with constants c1, c2.
