In a One-Way ANOVA, it is essential to do Post-Hoc analyses (comparisons) because
Group of answer choices
a. The Post Hoc tells us if there is a significance between “all groups combined” while the F ratio tells us where only one difference is.
b. The F ratio only tells us there is a significance between “all groups” and the Post Hoc comparisons show us where that difference is in each “pair” of groups.
c. The F ratio tells us if there is a significance within each level and the Post Hoc confirms there is a significance between “all groups combined”.
d .The Post Hoc tells us if there is a significance between “all groups combined” to confirm the significance of the F.

QUESTION 1 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 4 groups (J = 4), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places. QUESTION 2 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 6 groups (J = 6), what would...

Why must post hoc analyses be conducted when the Fobt > Fcrit? ANOVA is only telling you that there is a/ARE difference(s), not which groups are different. ANOVA has little power, so one must continue to look for differences to find them. Error sources have been found, now they need to be measured. Confidence intervals will help construct a range of possible values a mean could have. In order to measure the effect of the independent variable on the dependent...

I understand that one way ANOVA tells me that at least two groups are different from each other, however it doesn't tell me which groups are different. If the results of my ANOVA were to return a significant f-statistic, how do I determine which ad hoc test I need to run to tell me exactly which groups have a difference in means?

In an analysis of variance ANOVA, a post-hoc HSD test is Select one: a. done when the null hypothesis is rejected. b. done before the computed F is compared to the critical value of F. c. not done if all the means are similar except one. d. always done when there are four or more groups.

In a one way-ANOVA with F test, the F value tends to decrease when: SStotal increases SStotal decreases SSwithin increases SSbetween increases Tukey's honestly significant difference (HSD) test of post-hoc analysis should be used only if: the omnibus null hypothesis in an AVOVA is retained. the omnibus null hypothesis in an AVOVA is rejected. the all the groups have the same sample size. the distributions are skewed.

When 3 or more groups are included in an ANOVA, and the probability level indicates that the null hypothesis should be rejected, what does this tell the researcher? Group of answer choices That each mean is significantly different than every other one Specific post hoc analyses should be done to determine where there are group differences Which groups are different from which other groups It will be necessary to perform t-tests on each of the pairs of means to determine...
Which of the following statements about the one-way ANOVA are correct?
Which of the following statements about the one-way ANOVA are correct? (Select all that apply) The larger the variability within groups relative to the variability between groups, the larger the F test statistic tends to be. The results of the ANOVA F test does not tel us which groups are different or how different they are. An F-distribution is symmetrical about 0 and extends indefinitely in both directions In a one-way ANOVA, if the null hypothesis is rejected, we conclude that the population means...

Preliminary data analyses indicate that it is reasonable to consider the assumptions for one-way ANOVA satisfied. Perform the required hypothesis test using the critical-value approach. At the 0.01 significance level, do the data provide sufficient evidence to support the claim that a difference exists between the population means of the three different brands?
