The validity of the design of experimental research studies is a fundamental part of the scientific method, [2] and a concern of research ethics. Without a valid design, valid scientific conclusions cannot be drawn.
This method represents the most extreme form of intervention in observational methods, and researchers are able to exert more control over the study and its participants. [2] Conducting field experiments allows researchers to make causal inferences from their results, and therefore increases external validity.
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.
In qualitative research, a member check, also known as informant feedback or respondent validation, is a technique used by researchers to help improve the accuracy, credibility, validity, and transferability (also known as applicability, internal validity, [1] or fittingness) of a study. [2]
In psychometrics, criterion validity, or criterion-related validity, is the extent to which an operationalization of a construct, such as a test, relates to, or predicts, a theoretically related behaviour or outcome — the criterion.
Psychological statistics is application of formulas, theorems, numbers and laws to psychology. Statistical methods for psychology include development and application statistical theory and methods for modeling psychological data. These methods include psychometrics, factor analysis, experimental designs, and Bayesian statistics. The article ...
These benefits have the potential to translate into greater external validity and generalizability for the study. For instance, in web-based experiments there is less reliance on data gathered from populations of Western undergraduate students who are often used as the default research subjects in social science disciplines.
