In which of the following cases would a MANOVA analysis be most appropriate?
a. There is more than one dependent variable.
b. All of the variables are continuous.
c. The researcher wants to study the relationship between gender and ethnicity.
d. A structural equation analysis has already been performed.
One of the advantages of a structural equation analysis is that
a. only the relationships between nominal variables need to be tested.
b. relationships among latent variables can be studied.
c. there is a smaller chance of a placebo effect than in correlational studies.
d. p-values do not need to be set at .05.
Which of the following is a disadvantage of a MANOVA analysis?
a. Independent variables are related to the dependent variables.
b. It requires multiple F tests.
c. The likelihood of a Type 1 error is increased.
d. At least three independent variables are needed for reliability.
Which of the following designs would be most likely to utilize an exploratory factor analysis?
a. A study predicting a measure of conformity during emergency situations
b. A study that has measured a number of personality characteristics related to helping
c. A one-way experimental design with one dependent measure of helping
d. A study assessing a measure of helping behavior across cultures
To decrease the likelihood of making a Type 1 error during the means comparison process, a researcher could
a. compare all means within the study.
b. eliminate all data that supports the null hypothesis.
c. only conduct pairwise comparisons and only if the F value is significant.
d. increase alpha.
After testing the F value in an ANOVA, the researcher may want to follow up with
a. post hoc or a priori contrast analyses
b. a multiple regression analysis
c. a MANOVA
d. a post-experimental correlation
Loglinear analysis is a better statistical test than ANOVA when predicting a nominal dependent variable because
a. p-values are always lower in ANOVA.
b. ANOVA should only be used when the dependent variable has an approximately normal distribution.
c. loglinear analysis is easier to compute.
d. loglinear analysis creates more Type 2 errors.
Natalie is interested in predicting interpersonal attraction from knowledge about proximity and physical attractiveness. She first enters these two variables in her analysis. Then, after obtaining preliminary results, she adds the predictor variables of income and status. Natalie is using which of the following?
a. Factor analysis
b. Simultaneous multiple regression
c. ANOVA
d. Hierarchical multiple regression
What statistical analysis would be best used to predict levels of overall aggression from knowledge about blood pressure and eating habits?
a. Chi-square
