Experience 11 - Hypothesis Testing (Part 1)

Hypothesis Testing: The Beginning and The End

Why

The culmination of all our hard work so far this semester will by the study of hypothesis testing. In this experience we will examine each part of the process conceptually and avoid the calculations. Thorough understanding of these mechanics will ensure you do not make the common mistakes that plague the uninformed. Close examination of each piece is crucial for the learning the next experience. 

Learning Objectives:

• Know the general process of hypothesis testing using p-values
• Understand type 1 and type 2 errors
• Learn how to write hypotheses
• Learn how the decision is used to make a formal conclusion.

Performance Criteria

• The learner will translate written scenarios into corresponding null and alternative hypotheses using correct notation for mean and proportion tests.
• The learner will interpret the meaning of type 1 and type 2 errors for a given problem.
• The learner will write a conclusion in complete sentences that relates the decision to the original hypotheses and includes the level of significance.

• writing hypotheses
• interpreting errors
• writing conclusions
• the overall process

Plan

1. Review - Read the above components and post any questions in the forum below. 
2. Practice - Complete the practice exercises that follow.
3. Think - Answer the Critical Thinking questions in the "Critical Thinking" forum. 
4. Apply - Complete the Application Problems and upload your completed files.

If you have any questions about the content (readings, problems, etc.) then post in the "Questions about Experience 11" forum. 

The class will work together to create a wiki for inferential statistics. I will provide an outline and each of you will add at least one point (one or two complete sentences). Use the following guidelines

• Type your name in parentheses next to your contributions
• Try and keep it general - no examples.
• Check to make sure you are not repeating someone else.
• If you correct someone else, use strike-through (example) instead of deleting what they wrote. 
• Put things in your own words, don't just copy from the book.
• Make sure you put your response in the right place, use my outline as the guide.
• Use correct symbols or formulas where necessary. The Math Symbols button is available for you to use.

Your contribution to the Wiki is due by June 03, 2016
