Autocorrelations
the correlation of one variable with itself, measured at two different times

2
Control for
holding a potential third variable steady while investigating the association between two other variables

3
Criterion variable
the variable in a multiple regression that the researchers are most interested in understanding or predicting (may also be called the dependent variable)
New cards
4
Cross-lag correlations
in a longitudinal design, a correlation between an earlier measure of one variable and a later measure of another variable

5
Cross-sectional correlations
in a longitudinal design, a correlation between two variables that are measured at the same time \
New cards
6
Longitudinal design
a study in which the same variables are measured in the same people at different points in time
New cards
7
Mediating variable
a variable that helps explain the relationship between two other variables
New cards
8
Multiple regression
a statistical technique used to test for the influence of third variables
New cards
9
Multivariate design
a study designed to test an association involving more than two measured variables
New cards
10
Predictor variable

a variable in an analysis using multiple regression that is used to explain variance in the dependent or criterion variable.
