Document Summary

Reviewing the three causal criteria: multivariate designs. A study designed to test an association involving more than two measured variables: covariance, temporal precedence, internal validity. Establishing temporal precedence with longitudinal designs: longitudinal design. In a longitudinal design, a correlation between two variables that are measured at the same time. In a longitudinal design, the correlation of one variable with itself, measured at two different times. In a longitudinal design, a correlation between an earlier measure of one variable and a later measure of another measure. Address directionality problem and help establish temporal precedence. Mutually reinforcing: longitudinal studies and the three criteria for causation. Because both variables measured in at least two different. Ruling out third variables with multiple regression analyses: multiple regression. A statistical technique that computes the relationship between a predictor variable and a criterion variable, controlling for other predictor variables. Help rule out third variables and address question of internal validity: measuring more than two variables.
