D-2 Distinguish between internal and external validity.
D.3 Identify threats to internal validity (e.g., history, maturation).
Uncontrolled environmental variables that may interfere with the outcomes and/or the effectiveness of an intervention and therefore the internal validity of the experiment.
Refers to the changes in a subject over the course of the study that result from natural growth and development.
D-2 Distinguish between internal and external validity.
D.3 Identify threats to internal validity (e.g., history, maturation).
Uncontrolled variables related to the environment, the measurement tools, or a data collector’s behavior that may interfere with the measurement of behavior and therefore impact the outcomes and/or the effectiveness

D.3 Identify threats to internal validity (e.g., history, maturation).
Any uncontrolled variables in the treatment setting that could impact the outcomes and/or the effectiveness of an intervention and therefore the internal validity of the experiment.
Any uncontrolled participant-related variables that may interfere with the outcomes of an intervention and therefore the internal validity of an experiment.
