Internal vs. External Validity What is internal validity? Extent to which the experiment shows the changes in the behavior are due to the independent variable and not the result of uncontrolled or confounding variables

Internal validity focuses on displaying a distinction that’s because of the impartial variable alone, whereas exterior validity outcomes will be translated to the world at giant.

internal validity) we are making the experiment more and more artificial and thereby it’s generalizability (external validity) suffers. An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques The information needed to determine the internal and external validity of an experimental study is discussed. Internal validity is the degree to which a study establishes the cause-and-effect relationship between the treatment and the observed outcome. Establishing the internal validity of a study is based on a logical process. External and Internal Validity ! Internal Validity – the degree to which the results are attributable to the independent variable and not some other rival explanation !

External Validity – the extent to which the results of a study can be generalized 7 In short, they have to be internally and externally valid. Although at face value, external and internal validity are literally opposite of each other, they both are working synergistically for the social relevance of your research. Examples of Research Validity For example, lab experiments have stronger internal validity than external validity because the environment is manipulated into what the researcher wants it to be. The use of random samples instead of non-random samples produces stronger external validity because it takes away possible bias (Cozby 2014).

In other words, it is the extent to which the results of a study can be generalized to and across other situations, people, stimuli, and times.
