An experiment’s quality is judged by two types of validity. These are known as internal and external validity. Description of Internal and external validity:

In different phrases, this sort of validity refers to how generalizable the findings are. For occasion, do the findings apply to different folks, settings, conditions, and time intervals? Internal validity : External validity : Meaning Internal validity is the level up to which an experiment or research is free from errors. Errors might include variations in measurement because of the independent variable. It is a degree up to which outcomes of the research could be inferred to the real-world on a large scale. Emphasizes on The External Validity of Experiments are administered consecutively to the same persons within the same or different studies, it is difficult and sometimes impossible to ascertain the cause of the experimental results or to generalize the results to settings in which only one treatment is present.
