Quizplus · Accepted Answer

Internal validity is the measure of whether the results of an experiment are due to the manipulation of the independent variable or whether other factors played a role. It involves controlling for extraneous variables and ensuring that the changes in the dependent variable are a direct result of the independent variable manipulation. External validity refers to the generalizability of the results, and extraneous validity refers to the extent to which the results of an experiment can be attributed to the specific participants or materials used. None of the above is not a valid answer as there is a correct option.
