The former identifies the strength of research methods, while the latter focuses on whether the outcomes can apply to the real world. Internal validity describes the conclusion's warranted level, while external validity defines the degree to which the research generalizes the result to other contexts. The former eliminates or addresses alternative results explanations while the latter generalizes the outcome. the observed differences in the dependent variable are directly related to the independent variable and not due to some other unintended variable.
