Anova Null Hypothesis F Value. The following section summarizes the ANOVA F-test. Our F-value of 330 indicates that the between-groups variance is 33 times the size of the within-group variance.
Jan 15 2018 Here we can see that the F-value is greater than the F-critical value for the alpha level selected 005. Compute an F-Statistic 4. In these results the null hypothesis states that the mean hardness values of 4 different paints are equal.
The null hypothesis is H 0.
How it should be interpreted especially when conducting a. Therefore we have evidence to reject the null hypothesis and say that at least one of the three samples have significantly different means and thus belong to an entirely different population. Since the actual F test statistic 323 is greater than the critical F value 315 we reject the null hypothesis. A significance level of 005 indicates a 5 risk of concluding that an association exists when there is no actual association.
