Discriminant analysis seeks to identify which combination of quantitative IVs best predicts group membership by a single DV that has two or more categories. T F In binary logistic regression, the DV is a dichotomous variable. T F Factor analysis and principal components analysis are different techniques, but they are very similar. T F Factor analysis allows the researcher to explore the underlying structures of an instrument or data set and is often used to develop and test a theory....
11. One-way multivariate analysis of variance (MANOVA) is utilized to simultaneously study two or more related IVs, while controlling for the correlations among the IVs. 12. One-way multivariate analysis of covariance (MANCOVA) investigates group differences among several IVs, while also controlling for covariates that may influence the DVs 13. Factorial multivariate analysis of variance (factorial MANOVA) extends MANOVA to research scenarios with two or more DVs that are categorical. 14. Factorial multivariate analysis of covariance (MANCOVA) extends factorial MANCOVA to...

A researcher wants to conduct an experiment to test if the size of reward and time of testing have a significant effect on a task performance. He plans to use use three levels of reward size (i.e. low, medium and high reward) and two times of testing (morning and evening). How many groups would he need to conduct this experiment, if he plans to use 2-factor ANOVA for independent samples for data analysis? A. 2 B. 4 C. 6 D....

If the USA wants to reduce its imports (to promote domestic production) from China due to its trade deficit with China, compare which policy works more effectively, an import quota or an equivalent tariff? Reflect harder to compare the market adjustment by quota or tariff when domestic supply decreases due to a higher wage in a new labour contract. Use a graph to support your analysis.
