The process through which the independent variable creates changes in a dependent variable is known as a/an:

The answer is the mechanism. The procedure over which the independent variable generates changes in a dependent variable is known as a mechanism. In addition, to say that variables have an association is to say that they empirically vary together and to establish time order, the independent variable must come first. A causal mechanism contains the identification of superseding variables and experiments can have only two contrast groups which are an experimental and a control cluster.
