Questions and Answers 2023
Multivariate Data Analysis - -Research that involves three or more, or that is concerned with
underlying dimensions among multiple
variables, will involve multivariate
statistical analysis.

-Variate - -A mathematical way in which a set of
variables can be represented with one
equation.
A linear combination of variables, each
contributing to the overall meaning of the
variate based upon an empirically derived
weight.

-Dependence techniques - -Explain or predict one or more dependent
variables.
Needed when hypotheses involve distinction
between independent and dependent
variables.
Types:
Multiple regression analysis
Multiple discriminant analysis
Multivariate analysis of variance
Structural equations modeling

-Interdependence techniques - -Give meaning to a set of variables or seek to
group things together.
Used when researchers examine questions
that do not distinguish between independent
and dependent variables.
Types:
Factor analysis
Cluster analysis
Multidimensional scaling

-Nominal and ordinal scales are - -nonmetric

-Interval and ratio scales are - -metric

-General linear model - -A way of explaining and predicting a dependent
variable based on fluctuations (variation) from its
