Scientific research cannot predict with certitude that the desired independent variable caused a change in the dependent variable. Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor. In-other-words there is a causal relationship between the independent and dependent variable. Internal validity This is about the validity of results within, or internal to, a study. It usually concerns causality, i.e.
