Statistics for Data Analyst

The post is about the MCQs Multivariate Quiz. There are 25 multiple-choice questions about Multivariate Analysis of Variance (MANOVA), its introduction, assumptions, interpretation, and real-life application. Let us start with the MCQs Multivariate Quiz.

Online multivariate statistics and Manova MCQs

1. MANOVA:

 Indicates that each of the dependent variables contributes equally to the test of significance

 None of these

 MANOVA makes assumptions which are rarely if ever met in research and so should be avoided

 A significant MANOVA means that all of the dependent variables are significantly associated with the independent variables

2. Where would you find the option for repeated measures MANOVA in SPSS?

 Classify

 Regression

 General Linear Model

 Multiple Response

3. An educational psychologist studies the influence of a child’s gender and their parent’s job on a number of behavioral outcomes. Based on the MANOVA output, for which of the following dependent variables was there an interaction effect?

 Pro-social

 Independent

 Conformist

 Co-operative

4. Which of the following statements is true of MANOVA?

 MANOVA allows us to have one DV and one IV

 MANOVA allows us to have two or more DVs and up to two IVs

 MANOVA allows us to have one DV and two or more IVs

 MANOVA allows us to have two or more DVs and one or more IVs

5. How does MANOVA handle the DVs in the analysis?

 The DVs are standardized and summed

 The DVs are entered sequentially into a model

 The DVs are compiled into a linear combination

 The DVs are entered stepwise into an analysis

6. Which of the following is true?

 The more dependent variables in a MANOVA the more statistically exacting is the outcome

 MANOVA uses the natural logarithm of the proportions in each group as the basis of its statistical calculation

 There should be equal numbers of independent and dependent variables in MANOVA

 Centroid is the term for the mean score of a group on a discriminant function

7. Which F-value is typically reported in a MANOVA?

 Hotelling’s trace

 Roy’s largest root

 Pillai’s trace

 Wilks’ lambda

8. In MANOVA:

 The dependent variables should show zero intercorrelations

 The independent variables should show a pattern of high, medium, and low correlations with the dependent variable

 The dependent variables should correlate at the level of 0.8 or greater to prevent goodness of fit problems

 The dependent variables should correlate moderately

9. An educational psychologist studies the influence of a child’s gender and their parent’s job on a number of behavioral outcomes. Based on the MANOVA output, how many dependent variables are used?

 6

 5

 2

 8

10. In MANOVA, there are:

 Several correlated independent variables at a minimum

 Especially stringent significance levels

 Several dependent variables

 Requirements that the variables demonstrate heteroscedasticity

11. Which of the following is true?

 MANOVA is a more advanced version of ANOVA which can be used for the same data as ANOVA

 MANOVA is best used with frequency data

 MANOVA can use scores as the dependent and independent variables

 MANOVA is usually best supplemented with a discriminant function analysis

12. The Hotelling multivariate $t^2$:

 Has nothing in common with MANOVA

 Is used in MANOVA to test whether the variances of the dependent variable meet the requirements of multifunctionality

 Is the equivalent of the t-test for multiple dependent variables

 Is used to perform multiple-comparisons of the means on the combined dependent variable in MANOVA

13. The problem of multiple comparisons is dealt with in MANOVA by:

 Using the Bonferroni correction

 Combining several dependent variables in a similar way to what happens in discriminant function analysis

 Using a priori comparison procedures

 Setting the significance level at a higher level

14. What use do multivariate analyses of variance have, if any?

 It doesn’t really have any use as it is perfectly adequate to use univariate analysis

 We can analyze many dependent variables in one analysis and reduce a type I error

 It can identify the many facets of a psychological factor

 It does not have a need for post hoc testing

15. MANOVA can lose degrees of freedom:

 In no circumstances since it effectively increases the degrees of freedom compared to other approaches

 When several dependent variables are used

 When the sample size is bigger than the number of dependent variables

 In comparison to other approaches where the dependent variables are highly correlated

16. What problem is associated with correlated DVs?

 It adds a confounding variable

 It introduces multivariate outliers

 It means that data is not normally distributed

 The individual contribution of each DV is difficult to compute

17. If MANOVA is statistically significant:

 It is legitimate to conclude that all groups are significantly different

 There is no reason to carry out discriminant function analysis

 All of these

 It is permissible to conduct ANOVA on each dependent variable without any adjustments to the significance levels for the multiple tests of significance

18. What would you use Box’s M test for?

 To test for normal distribution

 To examine homogeneity of variance-covariance matrices

 None of these

 To test for a plausible linear combination of the DVs

19. In one-way MANOVA, which variable must be continuous?

 Moderating Variable

 Independent Variable

 None of these

 Dependent Variable

20. An educational psychologist studies the influence of a child’s gender and their parent’s job on a number of behavioral outcomes. Based on the MANOVA output, which dependent variables affected the child’s gender?

 Independent and Co-operative

 Pro-social ,anti-social and conformist

 Pro-social, anti-social and co-operative

 Pro-social, anti-social and independent

21. In which of the following conditions can MANOVA be used? Check all possible options.

 One-Way

 With Covariates

 Many Independent Variables

 Two-Way

22. Which of the following has the closest relationship with MANOVA?

 Wald statistic

 Discriminant function analysis

 Durbin-Watson test

 Greenhouse-Geisser correction

23. What would this be interpreted as if Box’s M had an associated P-value of < 0.05?

 There are multivariate outliers present

 The assumption of homogeneity of variance-covariance matrices has been violated

 The corrected model should be accepted

 The data is normally distributed

24. Which statistical technique is most similar to MANOVA?

 Variance ratio test

 Estimated standard error

 Analysis of variance

 Factor analysis

25. An educational psychologist studies the influence of a child’s gender and their parent’s job on a number of behavioral outcomes. Based on the MANOVA output, which of the following is true?

 The only significant effect was for the child’s gender

 The only significant effect was the interaction

 Child’s gender, parental job and the interaction all had a significant effect

 Child’s gender and parental job were significant but there was no significant interaction
