Evaluating Design Choice and Threats to Validity in an Experimental Design Provide a 3-paragraph evaluation of the choice of design and threats to validity in an experimental design. Your response should include an evaluation of the choice of design, the author's rationale for the design choice, the types of validity presented and the critical differences among them, the author's performance in explaining them, and how you would assess the study's validity and the information you would require to do so.
