Quizplus · Accepted Answer

Internal validity refers to the extent to which a study is free from errors and confounds that could affect the results. In the context of experimental research, it specifically refers to whether the observed differences between groups can be attributed to the manipulation of the independent variable, rather than any other factors. External validity refers to the extent to which the results of a study can be generalized to other populations or situations. Content validity refers to the extent to which a measure represents all the facets of a particular construct. Construct validity refers to the extent to which a measure assesses the underlying construct it is intended to measure.
