The difference between quality data and data with bias depends on how people are screened and the data is treated. Currents in Electrial Circuits – Remember it! If the IV has caused any change in the DV, then the procedure is a valid one, but if there may have been confounding variables which affected the DV as well, then it will not have internal validity.
