Question

Quizplus · Accepted Answer

The level of effectiveness is the variable that is being measured and is therefore the dependent variable. It is dependent on the type of service delivery model being used. The independent variable would be the type of service delivery model itself, as it is the variable being manipulated in the study. The extraneous variable would be any other variable that could potentially affect the level of effectiveness, but is not being studied. The control variable would be any variable that is being held constant in the study to ensure that the results are not influenced by any other factors.
