Research Methods Unused Questions

In a longitudinal design, researchers can examine which types of correlations?

• cross-sectional correlations

• autocorrelations

• cross-lag correlations

• multivariate correlations

The 3rd variable problem is related to which criteria for causality

• covariance

• ruling out alternative explanations

• temporal precedence

• holding all variables constant

The most important correlations to examine in a longitudinal design are

• cross-sectional correlations

• cross-lag correlations

• autocorrelations

• alpha correlations

Longitudinal research designs help establish which criteria for causality?

• covariance

• temporal precedence

• ruling out alternative explanations

• holding all variables constant

One star (*) next to an effect size like a correlation coefficient tells us that

• p < .05

• p > .05

• p < .5

• p < .005

The directionality problem is related to which criteria for causality

• covariance

• temporal precedence

• ruling out alternative explanations

• holding all variables constant

A multivariate study has at least ____ variables.

In a longitudinal design, temporal precedence can be established when Variable X at Time 1 is correlated with Variable Y and Time 2 and when Variable Y at Time 1 is correlated with Variable X at Time 2.
