What are the different types of threats to External Validity?
bulgar [2K]

The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.

<h3>What are the threats to External Validity?</h3>

There are 7 major threats to external validity.

  • The first threat is sampling  bias, in which a sample is not representative of the population.
  • The second threat is history, where an unrelated incident can affect the results.
  • The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
  • The fourth threat  is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
  • The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
  • The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
  • The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.
