Explain the concept of counterbalancing variables and interventions in an alternating treatments design.
Fill in the blank(s) with the appropriate word(s).
Suggested answer points:Because the purpose of the design is to evaluate the more effective independent variable among one or more interventions, the researcher should ensure that each intervention is fully implemented and counterbalanced in several dimensions. Counterbalancing involves making sure that who is implementing the interventions, the time of day, day of the week, setting, and other possible confounding variables are counterbalanced so that no unintended "advantage" is provided for an intervention.
