Exterior and internal validity are two parameters that are being used to evaluate the results of a research analysis or procedure.

As a final note, let me add this: you don't ever "have" internal or external validity, you merely have evidence supporting internal/external validity. External validity is the validity of applying the conclusions of a scientific study outside the context of that study. 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. In contrast, internal validity is the validity of conclusions drawn within the context of a particular study.

Examples of Validity An example of a study with good internal validity would be if a researcher hypothesizes that using a particular mindfulness app will reduce negative mood. Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables. External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. The key difference between internal and external validity is that internal validity is the extent to which the researcher is able to make the claim that no other variables except the one he is studying caused the result whereas external validity is the extent to which results of a study can be generalized to the world at large. Internal validity is concerned with control of extraneous variable, whereas external validity stresses on the applicability of the outcome to the practical situations. Internal validity ascertains the strength of the research methods and design. Conversely, external validity examines the generality of the research outcomes to the real world.
