Internal validity is a scientific concept that addresses the relationship between two variables. It refers to the extent that a study can rule out or make unlikely alternate explanations of the

the strength of assigning causes to outcomes. For laboratory experiments with tightly controlled conditions, it is usually easy to achieve high internal validity. Internal validity is a way to measure if research is sound (i.e. was the research done right?). It is related to how many confounding variables you have in your experiment. If you run an experiment and avoid confounding variables, your internal validity is high; the more confounding variables you have, the lower your internal validity. internal validity the extent to which the effects detected in a study are truly caused by the treatment or exposure in the study sample, rather than being due to other biasing effects of extraneous variables.
