Factor analysis is considered a data reduction technique.

A mathematical way of simplifying factor analysis results is _____.

Which multivariate analysis statistically identifies a reduced number of factors from a larger number of measured variables?

Which type of analysis involves three or more variables?

Which of the following is a dependence method of analysis?

In cluster analysis, the researcher wants clusters to have high ______ within-clusters and high between-cluster ______.

Partial correlations measure the variance inflation among independent variables.

The basic types of multivariate techniques are primary methods and secondary methods.

All of the following are examples of dependence methods of analysis EXCEPT _____.

In factor analysis, communality is a measure of the percentage of a variable's variation that can be explained by the factors.

Which type of analysis attempts to predict a categorical dependent variable?

In multiple regression, the dependent and independent variables must be metric measures.

General Mills would like to "see" a picture of how its brands are perceived by consumers compared to competitive brands. Which statistical technique can measure brands in multidimensional space on the basis of respondents' judgements of the similarity of the brands?
