Which of the following is accurate?
A) threats to internal validity are increased by carefully controlling conditions
B) threats to external validity are decreased by carefully controlling conditions
C) threats to generalizability of research findings in experiments are unrelated to internal validity
D) threats to external validity are increased by carefully controlling conditions

Question

Quizplus · Accepted Answer

Careful control of conditions during an experiment can decrease threats to external validity by reducing confounding variables and increasing the likelihood that results will generalize to the target population. However, careful control may increase threats to internal validity by making it difficult to generalize beyond the specific experimental conditions. Threats to generalizability are related to both internal and external validity, as they involve the extent to which findings can be applied to larger populations and different contexts. Thus, option A and D are incorrect, and option C is partially correct but incomplete.
