Office Hours: TBA

TA: TBA

Course Objective: Train graduate students in the sciences to plan and conduct experiments and

data analysis.

Textbook: Ott and Longnecker, 2004. A First Course in Statistical Methods, Duxbury.

Other Materials: Datasets, assignments, and overheads available on class website.

Web Site: http://www.stat.ufl.edu/~winner/

Homework and Exams:

  1. Homework Assignments: There will be 7 assignments. You will have one week to hand them in from the time they are posted and shown in class. The assignments will involve a data analysis project and brief write-up. Homework projects will count for a total of 50% of the course grade. Any evidence of students handing in the same assignment will result in all students involved receiving a grade of 0 on the assignment.
  2. Exams: There will be 2 in-class exams. Each will be worth 10% of the course grade.
  3. Quizzes: There will be 6 quizzes administered through WebCT. You will take them online. Description of process will be given below. They will combine to be 30% of the course grade.
  4. Grading: Grades will be based on the total of 500 points from homework and exams. Grades are not negotiable (unless a mis-calculation is made in totalling points)
  5. Exams are Closed Book. You will bring Tables downloaded from the class website and can hand-write formulas/notes on back of them.
  6. Missed Exams: Any exams that will be missed must be confirmed as soon as possible, before the time of the exam. No make-up exams will be given.
  7. Late Homework: Will not be accepted and will receive a grade of 0. All homework must be handed in by hard copy. No e-mail will be accepted.

Prerequisites and Computing:

  1. STA 6166 has a pre-requisite of an introductory statistical course. The course begins with (very brief) introductory material and some motivated students take it successfully as a first course.
  2. You will need a computer for homework assignments. Examples will make use of EXCEL, SAS, SPSS, and JMP; but you may use any program you choose. Datasets will be posted on web in column formatted ASCII format and can be easily imported into any of these programs.

Exam Dates (Web-based Students will have exams posted on these dates):

Quizzes:

Will be assigned approximately every other week, and are administered through WebCT. Click "UF Fall Term", login using your Gatorlink ID, and select: STA 6166 (Winner). Four options are available on the toolbar (top right) of the page: My Grades, Assessments, Discussions, Mail. Click on "Assessments" to see the list of available quizzes. Start a quiz by clicking on it. Although each quiz is not timed, you are only allowed to submit your answers once. This is achieved by clicking "Finish". You can logout and come back in to the quiz as often as you choose (don't forget to "Save answer" to retain already answered questions), but once you click "Finish", that's it! A good option might be to print the entire quiz, work on it offline, and then return online to submit the answers. Each quiz will also have a deadline date by which you must submit it. You can check your grades at any time through the "My Grades" tool. Contact me through the "Mail" tool. If I start getting a lot of questions on a specific topic, I will put this in the "Discussions" tool.
