Need to answer 3 questions from a Research paper. Answers must be precise and accurate, not a generalized answer.
Length can be 1 or 2 paragraphs each depending on answer.
1) Identify and describe at least one threat to validity that you observed in the study. Remember to explain the problem you see, and classify it according to the type of validity it impacts (Internal, External, Construct, or Statistical Conclusion Validity).
2) Develop an alternative design to address the objectives of the study, and explain how your revised design addresses the threat(s) to validity that you identified.
3) Identify any ways in which the new study has more limits or threats to validity than the new one.
