External Validity Refers to the degree to which within-study inferences generalize or can be generalized to a target population. Refers to the extent to which study results can be applied to other individual or settings.

To sum up, internal validity is the cause and effect relationship in the study. On the other hand, external validity usually asks the question, “does this apply in the everyday real situations outside the laboratory?” Knowing the difference between internal vs external validity is important in order to come up with a successful social research.

The ultimate purpose of internal validity is to determine if conducted research is appropriate. You External Validity. Internal-validity errors that bias participants towards a certain response or behavior; External-validity errors that capture behaviors or situations which are not characteristic for our target audience; We’ll talk about each of these separately. But before we do, let’s note that validity is separate from reliability. Internal validity can be improved by controlling extraneous variables, using standardized instructions, counter balancing, and eliminating demand characteristics and investigator effects.
