Quizplus · Accepted Answer

Internal validity refers to the extent to which the observed effect of the treatment can be attributed to the treatment itself, rather than to other factors. By eliminating potential alternative explanations, an experimental design increases the internal validity of a causal explanation. Selection bias refers to a non-random assignment of participants to groups, experimental mortality refers to participants dropping out of the study, and treatment integrity refers to the extent to which the treatment is implemented as intended. While these factors can impact internal validity, they do not specifically refer to the ability of experimenters to eliminate potential alternative explanations in an experimental design.
