If you examined the effect of studying 0,1, or 2 hours a day on grades, how could you write the alternative hypothesis? - not all µ are equal The ANOVA ratio is composed of - between-group variability over within-group variability The ANOVA has ___ numbers for degrees of freedom. - 2 In a within-groups ANOVA, - the same people are tested under every condition With a significant ANOVA in which three conditions have equal n , we should - calculate Tukey’s HSD Within-groups variability refers to - differences in numbers within each condition

Unformatted text preview: Between-groups variability refers to- differences in numbers between condition One-ways mean- a study has one IV or quasi-IV. A between-groups IV or quasi-IV means- both of these may be true In ANOVA, an IV or quasi-IV is often called a _____.- factor Another name for the within-groups ANOVA is- a repeated-measures ANOVA If we examine an Fobt and fail to reject H0,- we must not compare means A significant effect occurs when- the Fobt is to the right of the Fcrit Each sun-of-squares term in ANOVA must be divided by ___ before we can calculate the Fobt value.- degrees of freedom If you examined the effect of studying 0,1, or 2 hours a day on grades, how would you write the null hypothesis?-µ1=µ2=µ3 If you examined the effect of studying 0, 1, or 2 hours a day on grades, what would be the value of k ?- 3 The first calculation in ANOVA gives us a number for____.- all of the variability in the data set In ANOVA, the shape of the sampling distribution- is skewed...
