Laboratory experiments are designed so as to:

A) control for confounding variables.
B) establish external validity.
C) be as close as possible to a real-life experience.
D) establish effective measurements for multiple variables.

Laboratory Experiments

Research methods that involve the manipulation of one or more variables in a controlled environment to observe the effects on behavior.

Confounding Variables

These are variables that the researcher failed to control, or eliminate, damaging the internal validity of an experiment by providing a possible alternative explanation for outcomes.

External Validity

How broadly the outcomes of a research project can be extended to different contexts and populations.
