External validity is the validity of applying the conclusions of a scientific study ... writing about industrial and organizational psychology, ... For example ...
Ecological validity, the ability to generalize study findings to the real world, is a subcategory of external validity. [6] Another example highlighting the differences between these terms is from an experiment that studied pointing [7] —a trait originally attributed uniquely to humans—in captive chimpanzees. This study certainly had ...
Over time, as the novelty wears off, the stress response decreases. This is a threat to external validity when individuals participating in a research study (a novel situation) perceive and respond differently than they would in the normal real world. [2]
For this reason, situation sampling significantly increases the external validity of observational findings. [2] Compared to when researchers only observe particular types of individuals, researchers using situation sampling can increase the diversity of subjects within their observed sample.
Field experiments offer researchers a way to test theories and answer questions with higher external validity because they simulate real-world occurrences. [6] Some researchers argue that field experiments are a better guard against potential bias and biased estimators. As well, field experiments can act as benchmarks for comparing ...
It is a significant threat to a research study's external validity and is typically controlled for using blind experiment designs. There are several forms of reactivity. The Hawthorne effect occurs when research study participants know they are being studied and alter their performance because of the attention they receive from the experimenters.
Validity has two distinct fields of application in psychology. The first is test validity (or Construct validity), the degree to which a test measures what it was designed to measure. The second is experimental validity (or External validity), the degree to which a study supports the intended conclusion drawn from the results.
[3] Criterion validity is typically assessed by comparison with a gold standard test. [4] An example of concurrent validity is a comparison of the scores of the CLEP College Algebra exam with course grades in college algebra to determine the degree to which scores on the CLEP are related to performance in a college algebra class.
