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).

Add Exercises 15.24-15.38, 15.41, 15.43, 15.44, 15.51, 15.54, 16.17, 16.21, 16.26, 16.31, 16.32

SPECIAL NOTE: This is a B and above assignment. I can help assign study material if you are seeking only a C, as this material is not required for a C. Please contact me at kcummins@collegestem.us.

These chapter covers content necessary for the following awards [grade level] and other previous awards:
        Margin of Error/Confidence Intervals (336-341)  [B] -this is a change to the syllabus
        Factors Impacting Accuracy and Precision (pp. 366, 370,+) [A]
        Relationship Between Bio. and Stat. Ho (pp. 343-346)[B]
        Accepting the Ho (p 347+)[B]

The supplemental A level readings for this week are related to this article and this article and the topics:
      Criticism of NHST and Appropriate use of the term significant [A]

Secondary Awards Assessment 2

This covers the awards found on primary assessment 1. Below are descriptions for the Secondary Assessments. Related deliverables are due by September 26th. In-class assessments are to be conducted September 21st.

Review eligibly requirements in the syllabus.

Alternatives
You are not required to complete the secondary assessments. You can instead take the final exam in order to receive awards. If you are not eligible for secondary assessments you can take the final exam to receive awards. It is not recommended to take many awards assessments on the final.

Collaborative Boundaries
Unlike the process you might use with your homework, the development of the materials you create for these assessments must be completed only by the student submitting the material. Conceptual questions can be worked out with other students or with your professor. If you are unsure about the boundaries ask your professor. Materially complete drafts can be reviewed by your professor prior to or on September 23rd. Use of the draft-revision process is recommended and this process it key in the learning process. It also allows students to determine if there work is adequate prior to submission (there shouldn’t be any surprises).

Evidence of Sufficiency
Each of the sections below describes what is required to receive a secondary award for the underlined topics.

Descriptions

Interpretation of Results from Observational and Experimental Studies (15) and (20)
Biologists should understand the limitations of interpretation when reviewing observational data. They should also know the benefit of randomization in experimental studies. The two are linked directly.

To gain either or both award(s), you will write a section that could be added to a chapter on study design for a book that could be used in an introductory statistics course. Later, you can decide if you would like for your work to be included in a new book.

The section will be on the interpretation of data from experimental and observational studies.

The section must introduce the concept of confounding in observational studies and explain why good experiments are able provide better evidence of causation than observational studies. The work should contain examples and at least two references to recent (last 6 months) news reports about biology (including medicine) where the issue of confounding is pertinent (or could have been if an experimenter had not been conducted). The work should also include at least two exercises for the end of the chapter problems. The problems should be helpful in building a conceptual understanding. All items should come with a worked out answer and a “note to instructors” explaining what concepts are taught, reinforced, or covered in the questions. These should be essay questions.

As part of the assessment, your instructor may question you orally about your work, after your final submission.

Note: Here is an example of an example from the popular news: http://tinyurl.com/7z2zdyr  (note, they only recently caught their error after a pesky statistician pointed out the problem.)

Other awards will be assessed in class.

Reminder and Notes

Reminders and Notes

  • You should use JMP for your homework problems. See here.
  • If you have no questions about the material, here is what to do.
  • Because not enough students are coming to class on Tuesday with completed homework sets, the homework problem rotation exercises won’t work out. I highly recommend students review their answers with each other and then target key problems for review, with their professor.Screen Shot 2013-09-05 at 9.16.48 AM
