b. F = SSBetween / SSTotal
c. F = MSBetween / MSWithin
d. F = MSWithin / MSBetween
Option c) is correct.
c. F = MSBetween / MSWithin
The One-way ANOVA F test statistic F = MSBetween / MSWithin
The One-way ANOVA F test statistic can be calculated using which formula? a. F = MSBetween...
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.
21. An ANOVA is used to evaluate the mean differences among three treatment conditions with a sample of n = 12 participants in each treatment. For this study, what is dfrotal?! a. 2 b. 11 C. 33 d. 35 22. Which of the following is expected if the null hypothesis is true for an analysis of variance (i.e., when the experimental manipulation has no effect)? a. SSbetween should be about the same size as SStotal b. SSbetween should be about...
Which of the following is expected if the null hypothesis is true for an analysis variance? a. SSbetween should be about the same size as SStotal b. SSbetween should be about the same size as SSwithin c. MSbetween should be about the same size as MStotal d. MSbetween should be about the same size as SSwithin
21. In one-factor ANOVA for independent samples, which of the following reflects a random variability of scores in the samples? A. MSbetween B. MStotal C. MSwithin D. A & B 22. A one-factor ANOVA is used to evaluate the mean differences in cognitive task performance between three experimental groups, with n = 15 participants in each group. If the computed F = 3.17, which of the following is the correct statistical decision? A. Reject the null hypothesis with either α...
dentify key characteristics of ANOVA tests. How is the F-statistic in an ANOVA test calculated? a.) The variance between the samples minus the variance within the samples b.) The variance between the samples multiplied by the variance within the samples c.) The variance between the samples plus the variance within the samples d.) The variance between the samples divided by the variance within the samples
A) A one-way ANOVA test: is a left-tailed test is a right-tailed test is a two-tailed test Can be either a right-tailed or a left-tailed test 1.B) The p-value of the ANOVA F test is a. Area below (left) the value of the test statistic of the corresponding F distribution b. Area above (right) the value of the test statistic of the corresponding F distribution c. Half of the area above (right) the value of the test statistic of the corresponding...
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...
The F test in one-way ANOVA models is just an expansion of the t test for independent samples. Select one: a. FALSE b. NEITHER c. TRUE
The F-test statistic that is calculated is called Select one: a. alpha b. F critical c. eta-squared d. F obtained
