A very helpful set of questions to study for each test can be found on the web at:      http://www.brookscole.com/cgi-wadsworth/course_products_wp.pl?fid=M20b&flag=student&product_isbn_issn=9780495017639&discipline_number=1.  On the left click on Tutorial Quiz.  Many of these will be used for multiple choice questions on the test.

A very helpful tool that is supplied with your textbook is V-mentor.  Check it out.  I believe each weekday from about 6 at night to 11, there is a mentor online to help with any homework problem you have.

            Go to www.learner.org and click on the tab  “view programs”.  Now click on “Against all odds” and scroll down and to the right of “1. what is statistics” click on the symbol .   On the days indicated turn in 1 page of notes from listening to the following videos:

 

            January 23rd      1 – What is statistics?

            January 30th      2 – Picturing distributions

February 6th      3 – Describing distributions

February 27th   17 – Binomial distributions

            March 6th           4 – Normal distributions

Expectations for Students:

 

            Students are required to:

 

1.      Attend all lecture and laboratory exercises except in the case of illness or unforeseen emergencies.  It is the student's responsibility to contact the instructor about any missed worked.

2.      Be punctual.  Tardiness is definitely not a good habit to develop.

3.      Read over and take notes on the indicated chapters before they are presented in class.  This activity mentally prepares one for the learning experience.  It also is important because it raises questions that one needs to have answered in order to fully understand the concepts presented.

4.      Study about 2 hours for every hour in lecture.

5.      Take exams on the scheduled dates.  An automatic grade of zero is recorded for any exam missed. (Unlike other classes I teach there will not be one exam grade that is dropped)

6.      Master the homework problems and turn them in on time.

7.      Keep all assignments until the final grade has been issued in case of recording errors.

8.      Quiz every Thursday over one problem from the last section covered on Tuesday.

9.      Do not schedule plane flights home before your finals are over.

10.  The last day to withdraw unrestricted is Feb. 1st  and with my signature March 28th.

11.  There is NO late homework.

 

Final Project

 

            The project is intended to provide you with an opportunity to see statistics applied to a question that we will decide together to pursue as a class.

 

Data collection and analysis:  We will be answering the particular question that we agreed upon during class.  We will either plan an experiment/survey, carrying it out and then analyzing the data, or use a data set that has already been collected.  Your report should describe the question that motivated the study, methods for collecting the data, the analysis of the data and your conclusions.  It is important to think carefully about and provide an adequate description of the methods used to design the study and collect the data (such as was it a randomized study?) along with any possible biases that might affect the conclusions.  The data analysis should rely on the procedures we discussed in the 2nd half of our course.

III.             Walk through the 5 step hypothesis test procedure – writing everything down in detail  (make sure all the math is shown).  “When in doubt list it out”.

IV.             Write a few paragraphs on how you would improve this project if you were to continue with the general line of research.

Assessment and Grading:

 

            Grading Scale –

            A = 90% to 100%

            B = 80% to 89%

            C = 70% to 79%

            D = 60% to 69%

            F = below 60%

 

Accommodation and Special Needs - Include the following statement: Your instructor is willing to make any reasonable adaptations for limitations due to any disability, including learning disability, in keeping with SWC policies and the Student Handbook.  Any student with documented certifiable special needs should contact the office of the Dean of Student Services on campus and they will inform me of the proper accommodations you require.  If you have a special need, including a learning disability, it is your responsibility to contact this office as soon as possible to discuss your accommodation needs.

 

Retention of Examinations and Assignments: Instructors will retain copies of student examinations and assignments not returned to students for one semester in case of dispute between a faculty member and a student in assigning or recording a grade. After that time, instructors may discard course materials in a manner that preserves student confidentiality.

 

E-mail Policy –  Students are issued an official Southwestern College student email address when they are admitted to the College. These addresses all have the same form: firstname.lastname@swcaz.edu. This is the only electronic mailing address recognized by the college. Students are responsible for all official college communications, including attachments, transmitted to this address.  SWC faculty and staff are not responsible for forwarding email to personal email accounts that are not assigned by the college. Students are required to check their SWC email on a daily basis.   

 

Withdrawal: Last day to withdraw unrestricted - Jan. 30th:  Last day to withdraw with signature of faculty - March 20th

 

 

Disclaimer note - Include: This syllabus is subject to modification.  The instructor will communicate with students any changes.
