Document Summary
Bivariate correlations: look at the association between two measured variables, variables can be quantitative or categorical, of the three causal rules, difficult to establish temporal precedence and rule out third variables. But not temporal precedence not sure which variable came first. And not internal validity no control for third variables: solution: cross-lag panel designs (longitudinal designs, solution: multiple regression. Some advanced correlational techniques can help establish causality: longitudinal designs, multiple regression designs, pattern and parsimony approach, does not establish 100% internal validity, but a step in the right direction. Adding a third variables helps to establish temporal precedence. Helps to establish temporal precedence: measure same set of variables in the same people at two different points in time. Interpreting data from longitudinal designs: cross-sectional correlations, autocorrelations, cross-lag correlations o. Cross-sectional correlations: look at whether two variables are correlated that are measured at the same time, same group of participants.
