In research, the ecological validity of a study means that the methods, materials and setting of the study must approximate the real-world that is being examined. Unlike internal and external validity, ecological validity is not necessary to the overall validity of a study.
Internal validity means. that the study measured what it set out to; external validity is the ability to generalise from the study to the readerâs. patients. With respect to internal validity, selection bias, information bias, and confounding are present to some. degree in all observational research. Selection bias stems from an absence of comparability between groups being. studied. Information bias results from incorrect determination of exposure, outcome, or both.
