Which is true about post hoc tests?
Tukey's HSD test is the most conservative post hoc test.
Tukey's HSD is used when all conditions are being compared.
Scheffe's test is the most common post hoc analysis.
None of the options.
Homework Answers
Post hoc analysis is done if we reject the null hypothesis in the analysis of variance test and there are many procedures for that, the Tukey HSD and Scheffe’s are widely used but Scheffe’s is most common.
Scheffe's test is the most common post hoc analysis.

Which is true regarding Scheffe's test and the Bonferroni method? Select one: O a. The Bonferroni Method can be used for samples with unequal size. O b. Scheffe's test can be used for samples with unequal size. O C. The Bonferroni Method calculates a critical value. S, to which all sample mean differences are then compared. O d. Scheffe's test uses multiple t-tests with reduced alpha values.

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.

8. Tukey's HSD test A Aa Sleep apnea is a disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavior problems, including hyperactivity, inattention, and aggression. A common treatment for pediatric sleep apnea is the surgical removal of enlarged tonsils and adenoids that are obstructing the airways. Suppose researchers at a sleep clinic are interested in the effect of surgical treatment...
