MANOVA requires:
a.) The dependent variables to be heteroscedastic.
b.) More than one outcome variable.
c.) Sphericity.
d.) A stricter significance level than ANOVA.
MANOVA requires that there are more than one outcome variables.
Option B is correct.
MANOVA requires: a.) The dependent variables to be heteroscedastic. b.) More than one outcome variable. c.)...
A multiple regression model has _____. a. at least two dependent variables b. more than one dependent variable c. more than one independent variable d. only one independent variable
Multiple variables can be correlated, affecting the outcome of the dependent variable. What's the process for determining if more than one variable contributes to the outcome of a single dependent variable.
An experimental design that contains both between-group and a repeated-measures variables and one continuous dependent variable is called a: a. Two-tailed test b. MANOVA design c. Mixed design d. One-tailed test
Both the χ2 and the 1-way ANOVA allow one to study the effects of more than 2 levels of an independent variable on a dependent variable. Explain why we need the χ2 when we already have the ANOVA to handle more than one level of the independent variable. What does the χ2 allow us to do that the ANOVA does not?
When sphericity is violated, what test should be used? a. ANCOVA b. MANOVA c. MANCOVA d. None of the above
22. Questions that address structure usually distinguish between independent and dependent variables O 2017 Taylor & Francis 23. When investigating the relationship between two or more quantitative variables, the T test is the appropriate test. 24. Prediction of group membership is evaluated by ANOVA, ANCOVA, MANOVA, and MANCOVA 25. Significance of group differences is evaluated by discriminant analysis and logistic regression.
The multiple correlation of several variables with a dependent variable is a) less than the largest individual correlation. b) equal to the correlation of the dependent variable to the values predicted by the regression equation. c) noticeably less than the correlation of the dependent variable to the values predicted by the regression equation. d) It could take on any value
A valid multiple regression analysis assumes or requires that Select one: O a. The dependent variable is measured using an ordinal, interval, or ratio scale O b. The residuals follow an F distribution O c. The independent variables and the dependent variable have a linear relationship O d. The observations are autocorrelated
a.What is a One-Way ANOVA? b. What is the dependent variable? c. What are the factor variables? d. Design levels________ levels Store size ___________levels e. To find out the differences in design, what tool would you use within SPSS? f. When is Tukey appropriate to use? g. What is used for a small number of comparisons? h. What does the ANOVA table exhibit? i. What are linear trends? j. Overall, why is ANOVA needed?
Define and describe the following variance analysis tools: A. one-way ANOVA B. ANCOVA C. MANOVA D. MANCOVA.
