The extent to which a particular variable being manipulated can be assigned the responsibility of the effect observed.The validity of the inferences drawn for the population under investigation. In general, internal validity can be influenced by three types of bias: (1) selection bias, (2) information bias, and (3) confounding bias. However, the distinction between these three is not always strict.
