Homework Assignment 9

Filed in Homework

Note to Students: This is a point in the semester where the focus of student efforts fork. Skip the topics that are appropriate for the grade level you are targeting to allow you to focus on the grade level appropriate material AND to give you time to catch up on topics that you have not received awards for as of yet. Please, work with your instructor to develop a study plan that will allow you to be successful on the next awards assessment on those “straggler” topics.

Review Chapter 17. 
 
This is a short chapter and covers content directly related to the the first example NHST and indirectly related to the Statistical Hypotheses Testing awards. the following awards for this material are[grade level]:
       

    • Inference about a Population Mean (pp. 407-421) [C]
       
    • Conditions for inference (pp. 422-424+)[B]


Check your knowledge as you are reading, using the Apply Your Knowledge questions and the Check Your Skills questions.
Add Exercises 17.27-17.34, 17.42.

Special note: You will be introduced to the t-distribution. Use it just like the normal distribution. Discover why we use the t-distribution, rather than the normal distribution in most real situations.

2. Repeated from last week. Review two articles. These articles and related awards are for students seeking advanced grades. If you are not, focus on the core material. After becoming familiar with statistical testing, review the articles on significance testing in the weblinks section of Blackboard.
Review the articles are titled, “Odds are its Wrong,” and “Do We Really Need the S-word?” Respectively, these articles address the awards:
    Criticism of NHST [A]
    Appropriate use of the term significant [B]

Solidify: Homework Assignment 8

Filed in Homework

Important Note to Students: I’m going to reset the schedule for the rest of the semester in the next couple days. Typically we would just jump into t-tests next. This semester we are going to stop and solidify what we have been working on.

Chapter 15 and 16
Review Chapter 15 and 16. These chapters help consolidate the connections between the previous topics. Check your knowledge as you are reading, using the Apply Your Knowledge questions and the Check Your Skills questions. If you can’t use the book’s applets, the java based simulations on the website with the sampling distribution simulations can be substituted.

Be sure to send your questions before Monday (and explain in some detail why you pick an exemplar question to be covered if you don’t have any questions).
