Answer: Wendy did not use random assignment
Explanation: Wendy's failure to randomly assign participants or subject to his research will pose a threat to the internal validity of his study. The internal validity of a study simply refers to the structure of an experiment and it's trustworthiness in establishing causal relationship between the applied treatment used a study and the observed outcome.
