Required Textbooks and Materials:

 

q       Agresti, A., and Franklin, C. (2007).  Statistics:  The Art and Science of Learning from Data, Prentice Hall.

q       Graphing Calculator TI83+ or similar Models.

q       Math XL (You can purchase the access code online from www.mathxl.com for $34.95.  (Your school zip code is 92182)

q       Class notes: Lecture notes for each chapter will be available on Blackboard: http://blackboard.sdsu.edu. The course syllabus, class schedule, practice midterms, practice final, computer assignments, and warm-ups can also be found on blackboard.  We will communicate frequently through blackboard so please check the announcements page daily.

 

Course Description: Topics include descriptive statistics, data displays, measures of central tendency and variability, random variables, sampling distributions, estimation and hypothesis tests for means and proportions, linear regression and correlation.

 

Course Goals:  After completing the course, students should be able to:

 

q  Recognize whether an experiment or survey is well designed.

q  Understand how to produce a sample that represents the population of interest.

q  Summarize data using both graphical and numerical methods.

q  Produce and interpret statistics and graphs, using regression techniques, to describe the relationship between two numerical variables.

q  Test and interpret hypotheses for the linear regression model.

q  Use basic probability principles in a variety of practical applications

q  Identify, and calculate probabilities for, binomial and normal probability distributions.

q  Understand the concept of sampling distributions.

q  Use statistical methods to construct, and interpret, interval estimates for population means and proportions. The student will learn both small sample (t-distribution) and large sample (normal distribution) methods.

q  Formulate, test and interpret various hypotheses for population means and. proportions.

q  Construct confidence intervals, and test hypotheses for differences in two population means or proportions, and interpret results.

q   Use a statistical software package to display data and carry out statistical data analysis

 

Grading: Your grade will be composed of the following items for a total of 500 points:

 

Homework                                    70  (8 assignments, lowest one dropped, 10 points each)

            Computer Assignments                  40  (2 assignments, 20 points each)

            (Using Minitab)   

           

Midterms                                      240  (3 midterms, 80 points each)

            Final                                             150

 

The letter-grade cut-offs will be determined at the end of the semester based on the distribution of final grades, but will roughly follow A:463-500, A-: 450-462, B+: 438-449, B: 413-437, B-:400-412, C+:388-399, C:363-387, C-:350-362, D:300-349, F: 300 and below.

 

Homework: There will be eight MathXL homework assignments.  Your lowest homework assignment score will be dropped. MathXL will not allow you to submit late homework.  The MathXL website is www.mathxl.com. All homework assignments must be turned in online using MathXl by Sunday 11:00 pm of the week that is due.

 

Computer Assignments: There will be two computer assignments, worth 20 points each requiring the use of Minitab.  You will receive accounts to use the labs in GMCS 422/425/428 where Minitab software is installed.  You can also download a free 30-day trial of Minitab for your home computer or rent a five-month copy for $29.99 from http://www.minitab.com/products/minitab/demo/default.aspx?ad=mssbn2

      Once the semester is underway, computer lab hours will be posted on Blackboard.

 

Exams: We will have three midterms tentatively scheduled for Feb 25th, March 24th and April 21st.  The final exam is scheduled for Monday, May 12th from 10:30am-12: 30pm.  The exams will be closed book, though you may bring one side of an 8.5x11 sheet of handwritten notes to each midterm and two (single-sided) 8.5x11 sheets of handwritten notes to the final exam.  No photocopying of texts or handouts is permitted. Statistical tables will be provided.  Practice exams with solutions will be posted on Blackboard.  The exams are to be held in a secure environment. You may not use any other electronic devices such as cell phones, computers, pagers, radios, MP3 players, I Pods, palm pilots, or blackberries.  Any student whose phone rings audibly during an exam will have 5% deducted.  Any student who answers a phone during an exam will receive a zero.

 

DSS:

If you have a documented disability requiring special accommodation, please come see me during the first week of class. DSS is the campus office responsible for determining and providing appropriate academic accommodations for students with disabilities.  Students needing these services should contact DSS by phone (594-2653) or by email dsstest@mail.sdsu.edu.

 

Academic Dishonesty:

Cheating is taken very seriously. Violators will be prosecuted through the judicial procedures office division of student affairs, San Diego State University, San Diego, CA   92182-0178 , phone (619) 594-6455.

 

Additional Items:

q Put away ipods, other musical devices, and newspapers before the start of class,

q Please do not talk during lecture.  It is both disrespectful and disruptive.
