Internal validity vs external 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 provide greater internal validity than field data, while field data provide greater ecolog ical validity and we argue a lower burden for establishing external validity. To under stand these rank orderings, we turn to common threats to both internal and external validity and discuss how each method addresses these threats (see figure 1 for a It has internal validity because what you manipulated (Twinkie eating) affected your dependent variable, but that conclusion does not really bring any enlightenment to your theory. The second basis for evaluating your research design is to assess its external validity. External validity means that we can generalize the results of our study.

To sum up, internal validity is the cause and effect relationship in the study. The key difference between internal and external validity is that internal validity is the extent to which a researcher will be able to make the claim that no other variables, except the one he’s studying, caused the result; whereas external validity is the extent to which results of the research can be generalized because of involvement of more than one variables.
