Document Summary

Validity extent to which research conclusion corresponds with reality is the researcher"s conclusion true/correct. Internal validity extent that study provides evidence of a cause & effect relationship between the independent and dependent variables: experiment with high internal validity the iv really did cause the dv to change. Threats to internal validity major sources of confounding: ambiguous temporal precedence two things are clearly related but it"s not obvious which one is the cause and which one is the effect ex. Gender cannot be assigned to one gender. Construct validity extent to which the results support the theory behind the research: ex. Beck anxiety inventory to see if fingernail biting is useful way of classifying anxiety. In construct validity strive to rule out all other possible theories that could explain the results may have to do another study to rule out threats.
