What is External Validity in Research? - Definition & Examples

1. What is External Validity in Research? - Definition & Examples

External validity in research is how well the results of a study can be generalized to the world. Take a deeper look at the definition of external validity, the importance and examples of external validity, and control vs. generalization in this lesson.

Requirements of External Validity: Internal Validity & Replication

2. Requirements of External Validity: Internal Validity & Replication

External validity says that study results can be replicated and generalized to the world. Explore the requirements of external validity and learn about internal validity, replication, control, and generalizing.

Generalization & External Validity

3. Generalization & External Validity

External Validity, a form of generalization, measures the extend to which results can be generalized to the rest of the population. Explore types of generalizations in three categories: Across subjects, concepts and procedures, and applying research beyond the lab.

Threats to External Validity: Sample Characteristics, Stimulus Characteristics & Experimental Arrangements

4. Threats to External Validity: Sample Characteristics, Stimulus Characteristics & Experimental Arrangements

External validity refers to the generalizability of the research results. Explore what external validity is and how it can be affected by three main threats: sample characteristics, stimulus characteristics, and experimental arrangements.

How Novelty Effects, Test Sensitization & Measurement Timing Can Threaten External Validity

5. How Novelty Effects, Test Sensitization & Measurement Timing Can Threaten External Validity

One of the greatest considerations in research is external validity, or how well the results can be generalized to a greater population. Learn to define external validity and identify three threats to it: novelty effects, test sensitization, and measurement timing.

Reactivity of Experimental Arrangements & Assessment: Threats to External Validity

6. Reactivity of Experimental Arrangements & Assessment: Threats to External Validity

Reactivity of experimental arrangements and assessment is the reaction by subjects to experimental conditions, which can hinder or threaten external validity. Learn how to define external validity and the two main types of reactivity, and discover explain their effects on validity.

Methods for Increasing External Validity

7. Methods for Increasing External Validity

External validity refers to how the outcome of a study can be applied to the world. Explore the methods for increasing external validity including aggregation, nonreactive measures, and field research.
