Abstract

Four types of validity are to be considered when evaluating whether research findings can be interpreted as a legitimate test of a hypothesized relationship between an independent and a dependent variable. They are construct validity, statistical conclusion validity, external validity, and the one at which experiments excel: internal validity. This article focuses on validity in experimentation.
