What is the main advantage of experimentation over correlation in determining causal relationships?
A)Experimentation offers the possibility of controlling for all potential third variables at once.
B)Experimentation involves multiple variables,whereas correlation involves only two variables.
C)Experimentation systematically controls third variables one at a time,in sequence.
D)Experimentation uses the matched pairs and matched samples techniques to control for specific third variables.

The main advantage of experimentation over correlation is that experimentation offers the possibility of controlling for all potential third variables at once. In an experiment, researchers can manipulate the independent variable, while controlling other variables that might affect the outcome. This makes it possible to establish causality between the independent and dependent variables, whereas correlation can only indicate the direction and strength of a relationship between two variables, without ruling out other possible explanations.
