Anova Null Hypothesis P Value. You run a one-way ANOVA on your data and get a p value of 033. In these results the null hypothesis states that the mean hardness values of 4 different paints are equal.
A general rule of thumb is that we reject the null hypothesis if Sig or p. A Tukey-HSD test can be done next but this is not relevant to my question. Now lets say that the same data has another variable ie another factor.
Usually a significance level denoted as α or alpha of 005 works well.
03292021 8 ANALYSIS OF VARIANCE ANOVA ANOVA PROCEDURE 1 State the null and alternative hypotheses 2 Specify the level of significance use 5 unless otherwise stated 3 Compute the test statistic F actual 4 Find the critical F value from F distribution table 5 Compare the F test statistic F actual with the critical F value F. The association is statistically significant.
