Chapter 9 exam Flashcards
_________________ are studies involving 2+ measured variables
Multivariate designs
Longitudinal designs help address _______________________.
Temporal precedence
Multiple regression analyses help address
____________________.
Internal validity
Pattern and parsimony can help establish ____________________.
Causation
____________________ are studies that measure variables over time
Longitudinal designs
________________ test whether two variables measured at the
the same point in time are correlated
Cross-sectional designs
Cross-sectional designs do not provide information regarding ________________________.
Temporal precedence
_____________________ are the correlation of each variable with itself across
time
Autocorrelations
_________________ designs are correlations of the degree to which an earlier
measure of one variable is associated with a later
measure of the other variable
Cross-lag
Multivariate designs allow us to _______________ for other
factors that might influence the association of
interest
Control
___________________ is a statistical analysis that can help rule out
potential third variables, by assessing the
relation of interest while controlling for
suspected third variables
Multiple regression
___________________ is used when analyzing 3+ variables
Multiple regression
Larger ____________________ values are indicative of stronger
associations
beta (β)
Causation is not easily established in _______________________________
designs
Multiple regression
_____________________ is the degree to which a scientific theory provides
the simplest explanation of a pattern
Parsimony
__________________ are variables that help explain the relation
between two other variables
Mediators (mediating variables)
___________________ impact both variables, leading to a
relation between them
Third variables
What are the similarities between Mediators vs. Third variables?
– Both involve multivariate research designs.
– Both can be detected using multiple
regression.
What are the differences between Mediators vs. Third variables?
– Third variables are external to the bivariate
correlation (problematic).
– Mediators are internal to the causal
variable (not problematic).
The ______________________ variable comes between the two
original variables
Mediating
A ____________________ is a new variable that changes the original relation
between two variables.
Moderator
Once you consider the _______________ variable, your relation goes
away.
Third
This relation with a __________________ variable occurs because variable A influences
the mediator variable (C) which influences variable
B.
