High internal validity is achieved when an experiment is designed and conducted in such a way that it can be concluded that the observed effects were due to the manipulation of the independent variable and not due to other factors. Assuming experimental and control groups are equal at the start and using appropriate controls are key methods to ensure that other variables are not influencing the outcome, thus leading to high internal validity.
