PSY 510 Short Paper: The Importance of Random Assignment Guidelines and Rubric

This short paper assignment will require you to explain the importance of random assignment in psychological research. Prompt: Imagine that you are an online tutor for an undergraduate Research Methods course. One day, you get this email:

Dear Tutor, I am having some trouble understanding why it is so important to randomly assign participants to experimental conditions. It seems to me that if you have a large enough sample, the results would probably be valid even if you didn’t bother to randomize the participants. Why is it important to go through the trouble of randomizing participants? Also, if you are going to randomly assign participants, how should you do it?

Respond to this student’s email, being sure to explain the concepts at the appropriate level for an undergraduate. In your response, be sure that you explain why it is important to randomize participants. Also, explain some of the ways that a researcher can randomly assign participants. Last, be sure to explain how a researcher can make valid conclusions even in situations where randomization is not possible.

Your paper should include all of the following elements:

·  Discussion about the importance of randomization in a psychology experiment

·  An explanation of the methods of randomization that a researcher can use to randomly assign participants

·  An explanation of how a researcher can draw conclusions without randomization

Guidelines for Submission: Your paper must be submitted as a Microsoft Word document with double spacing, 12-point Times New Roman font, and one-inch margins. This paper should be a minimum of three pages (not including cover page and references).

Instructor Feedback: This activity uses an integrated rubric in Blackboard. Students can view instructor feedback in the Grade Center. For more information, review these instructions.
