Introduction Assessing interdependence between
variables allows the researcher to summarise and understand a large number of independent variables.
Techniques for grouping X variables include: Factor analysis, to reduce and summarise
data. Cluster analysis, to classify objects.

Interdependence TechniquesInterdependence exists when no
single variable or group of variables among those under consideration can be defined as being dependent or independent.
No one variable can be predicted or explained by the others.
Need to analyse all the variables in the data set simultaneously.

Summary of Selected Interdependence Methods – Factor analysisFactor analysis is used to
summarise the information contained in a large number of variables into a smaller number of subsets called factors.

Summary of Selected Interdependence Methods – Cluster AnalysisCluster analysis is used to
classify respondents or objects (e.g. products, stores) into groups that are homogeneous, or similar within the groups but different between groups.

Factor AnalysisA technique to summarise
information contained in a large number of variables into a smaller number of subsets or factors. To simplify the data. No distinction between X and Y
(dependent and independent variables), they are analysed together.

Factor Analysis - Factor Loadings
The correlation between each factor score and each of the original variables.
Each factor loading is a measure of the importance of the variable in measuring the factor.
From –1 to +1 A ‘high loading’ or correlation means
that the variable helps define the factor.

Factor Analysis
Naming Factors Combine intuition and knowledge of
the variables with an inspection of the variables that have high loadings on each factor.

Factor AnalysisHow many factors?
Look at the percentage of variation.
Factor Scores Produce composite variables when
applied to a number of variables. A factor is a weighted summary
score of a set of related variables.

Cluster AnalysisMarketing researchers draw upon
cluster analysis to classify objects or respondents into groups that have something in common.
Cluster analysis pinpoints what is homogeneous/similar within groups but heterogeneous/different between them.

Cluster AnalysisAn Interdependence method—
why?Groups objects within each
group that are similar on a variety of measures.
Be aware of applications.
