7.One conclusion you might reach (hint) after completing the readings for this assignment is that there are no bad designs, only bad design choices (and implementations).

If not, please use the original research question you chose) 1.What research question(s) does the study address? 2.What is Goldberg's rationale for the study? Was the study designed to contribute to theory? Do the results of the study contribute to theory? For both questions: If so, how? If not, why not? 3.What constructs does the study address? How are they operationalized? 4.What are the independent and dependent variables in the study? 5.Name the type of design the researchers used. 6.What internal and external validity threats did the researchers address in their design? How did they address them? Are there threats they did not address? If so how does the failure to address the threats affect the researchers' interpretations of their findings? Are Goldberg's conclusions convincing? Why or why not?
