By controlling all extraneous variables and randomly assigning participants, the experimenter can increase the internal validity of the study, which refers to the extent to which the observed effects are due to the manipulation of the independent variable rather than other factors. The other options are not directly related to this method of experimental design. Interjudge reliability refers to the extent to which different judges or raters provide consistent ratings, replicability refers to the ability to replicate the study's findings in future research, generalizability refers to the extent to which the findings can be applied to other populations or contexts, and p-values are a statistical measure used to determine the significance of results.
