Extraneous variables Extraneous Variables: Aspects of the environment you CAN control that could affect the outcome of an experiment. (e.g. the time of the session, the lighting in the room (assuming lights work), the temperature in the room (assuming the thermostat works) ect. Confounding variables Confounding variables: Factors that you CANNOT control that could potentially influence the outcome of an…
Why Conduct Baseline Probes The purpose for conducting baseline probes is to establish a control in an experiment. In order to know whether or not an intervention (independent variable) changed a behavior (dependent variable) you would need a reference as to how often the behavior occurs prior to starting an intervention. You can learn some other very important things when…
Parametric analysis Parametric analysis refers to evaluation the intervention (treatment ) or independent variable in an applied behavior analysis (ABA) study or experimental design There are two ways to describe the independent variable: parametric and nonparametric. If an independent variable is nonparametric- it is either on or off. The easiest way to think of this is a light switch. The…
