Factorial analysis of variance (factorial ANOVA) extends ANOVA to research scenarios with two or more IVs that are categorical. True or False Factorial analysis of variance (factorial ANCOVA) examines group differences in a single quantitative dependent variable based upon two or more categorical independent variables, while controlling for a covariate that may influence the DV. True or False One-way multivariate analysis of variance (MANOVA) is utilized to simultaneously study two or more related IVs, while controlling for the correlations among...

QUESTION 19 10 points in a one way ANOVA if the variance of the first treatment mean is 0.2, what is the variance of the second treatment mean? (Assume all assumptions are met for this ANOVA) O Greater than the variance for the first treatment mean O We cannot know without the data used in the ANOVA O The same as the variance for the first treatment mean O Less than the variance for the first treatment mean QUESTION 30...
1. True or False? 2. True or False? To compute a t statistic, you must use the sample variance (or standard deviation) to compute the estimated standard error for the sample mean. True False The 95% confidence interval for the difference between two treatment means extends from-2.50 to +5.50. Based on this information, you can conclude that there is no significant difference between the treatments at the .05 level of significance True O False To compute a t statistic, you...
