Before beginning work on this week's discussion post, review the following resources:

• Doing Discussion Questions Right 
• Expanded Grading Rubric

From the below list, select one topic for which you will lead the discussion in the forum this week. Early in the week, reserve your selected topic by posting your response (reservation post) to the Discussion Area, identifying key words about your topic in the subject line.

By the due date assigned, research your topic and start a scholarly conversation as you respond with your initial or primary post to your own reservation post in the Discussion Area. Make sure your response does not duplicate your colleagues' responses:

Topic:

• Distinguish between parametric and non-parametric tests.

As the beginning of a scholarly conversation, your initial post should be:

• Succinct—no more than 500 words.
• Provocative—use concepts and combinations of concepts from the readings to propose relationships, causes, and/or consequences that inspire others to engage (inquire, learn). In other words, take a scholarly stand.
• Supported—scholarly conversations are more than opinions. Ideas, statements, and conclusions are supported by clear research and citations from course materials as well as other credible, peer-reviewed resources.
