whole or in part.
1. Compare and contrast dependence and interdependence techniques. List the statistical techniques for
both.
ANS:
When hypotheses involve distinction between independent and dependent variables, dependence
techniques are needed. Multiple regression analysis, multiple discriminant analysis, multivariate
analysis of variance, conjoint analysis, and structural equations modeling are all dependence
techniques. When researchers examine questions that do not distinguish between independent and
dependent variables, interdependence techniques are used. No one variable or variable subset is to
be predicted from or explained by the others. The most common interdependence methods are factor
analysis, cluster analysis, and multidimensional scaling.

2. List the steps in interpreting a multiple regression model.
ANS:
Multiple regression models can be interpreted using these steps:
(1) Examine the model F-test for significance.
(2) Examine the individual statistical tests for each parameter estimate.
(3) Examine the model R2.
(4) Examine collinearity diagnostics, such as variance inflation factors (VIF) for each variable to
detect multicollinearity.

3. Explain how MANOVA models differ from ANOVA models.
ANS:
An ANOVA or MANOVA model represent a form of the general linear model (GLM). ANOVA can be
extended beyond one-way ANOVA to predict a dependent variable with multiple categorical
independent variables. Multivariate analysis of variance (MANOVA) is a multivariate technique that
predicts multiple continuous dependent variables with multiple independent variables. The
independent variables are categorical, although a continuous control variable can be included in the
form of a covariate.

4. Explain why and how a business researcher uses factor analysis.
ANS:
© 2010 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in
whole or in part.
Factor analysis is a prototypical multivariate, interdependence technique. It is a technique of
statistically identifying a reduced number of factors from a larger number of measured variables. The
factors themselves are not measured, but instead, they are identified by forming a variate using the
measured variables. Factors are usually latent constructs like attitude or satisfaction or an index like
social class. A researcher need not distinguish between independent and dependent variables to
conduct factor analysis. Factor analysis can be divided into two types: exploratory factor analysis
(EFA) and confirmatory factor analysis (CFA). Exploratory factor analysis reveals how many
factors exist among a set of variables and what variables match up or “load on” which factors. A factor
loading indicates how strongly correlated a factor is with a measured variable. Factor analysis is
considered a data reduction technique that allows a researcher to summarize information from many
variables into a reduced set of variates or composite variables.

5. Explain how cluster analysis can identify market segments.
ANS:
Cluster analysis is a multivariate approach for identifying objects or individuals that are similar to one
another in some respect. It classifies individuals or objects into a small number of mutually exclusive
and exhaustive groups. Objects or individuals are assigned to groups so that there is great similarity
within groups and much less similarity between groups. The cluster should have high internal (withincluster) homogeneity and external (between-cluster) heterogeneity. Cluster analysis facilitates market
segmentation by identifying subjects or individuals who have similar needs, lifestyles, or responses to
marketing mixes.
