Which type of multivariate analysis should be used when a researcher wants to estimate the utility that consumers associate with different product features? - -conjoint analysis -Which type of mul ... tivariate analysis should be used when a researcher wants to identify subgroups of individuals that are homogeneous within subgroups and different from other subgroups? - -cluster analysis -Which type of multivariate analysis should be used when a researcher wants to reduce a set of variables to a smaller set of composite variables by identifying underlying dimensions of the data? - -factor analysis -Which type of multivariate analysis should be used when a researcher wants to predict a dependent variable based on the levels of more than one independent variable? - -multiple regression analysis -What type of analysis fits a plane to observations in a multidimensional space? - -Multiple regression analysis -For which statistical analysis is the following formula used? Y = a + b1X1 + b2X2 + b3X3 + ... + bn Xn - -Multiple regression -If "R squared" in a regression analysis is found to be .65, this means that ________ percent of the variation in the dependent variable can be explained by variation in the independent variable. - -65 -In regression analysis, when males are coded as "0" and females are coded as "1", what type of variables are being used? - -dummy variables -In multiple discriminant analysis, the dependent variable must be ________, while in multiple regression analysis, the dependent variable must be ________. - -nominal; metric -In multiple discriminant analysis, the discriminant score is typically identified as a(n) ________ score. - -Z -Which of the following techniques is most appropriate for analyzing one metric dependent variable and its relation to several metric independent variables? - -multiple regression -In factor analysis, a linear combination of variables that are correlated with one another is called a(n): - -factor -Which type of statistical analysis is used to determine what features a new car should have and how this car should be priced? - -conjoint analysis -In predictive analytics, which task deals with using regression to predict subgroup membership with high predictive accuracy? - -modeling -Multivariate statistical analysis procedures are a logical extension of both univariate and bivariate statistical procedures. - -true -Multiple regression fits a plane to observations in a multidimensional space. - -true -The goal of discriminant analysis is to predict a categorical variable. - -true -Cluster analysis is used to identify people who are similar to one another in regard to specific variables. - -true -The purpose of factor analysis is to simplify the data. - -true - [Show More]
