Experiments are generally high in internal validity because of the manipulation of the independent variable and control of extraneous variables. Studies are high in external validity to the extent that the result can be generalized to people and situations beyond those actually studied. 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. Therefore, construct validity consists of obtaining evidence to support whether the observed behaviors in a test are (some) indicators of the construct (1).

External validity refers to the extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical validity). External validity concerns the extent to which the (internally valid) results of a study can be held to be true for other cases, for example to different people, places or times. External validity can be improved by setting experiments in a more natural setting and using random sampling to select participants.

Internal validity “refers to the ability to draw conclusions about causal relationship from data” (Cozby, 2009, p.86). A research study would have internal validity if results of the study show a correlation between the cause and effect the researcher theorized.

Generalizability of findings is not assured even if internal validity of a research study is addressed effectively through design. Characteristics of internal validity Unlike other validity tests like the construct validity and external validity, the internal validity indicates if the covariance observed between the variables can be at all regarded as true causal relationship.
