Causal-comparative studies do not manipulate independent variables, but instead compare groups that differ on a particular variable, and then examine the relationship between the variable and the outcome. They cannot establish causation because the groups are pre-existing and not randomly assigned, meaning it is impossible to control for all other variables that might be influencing the relationship that is being studied.
