Course Description and Objectives The sequence of courses STA 2023-3024 provides students
with a firm foundation in the basics of applied statistical methods. The
prerequisite for this course is STA 2023, which covered chapters 1-8 in the
textbook (Data collection, graphical and numerical summaries, probability and
an introduction to statistical inference). Concepts from STA 2023 will be
reviewed as needed. Introduction to Statistics II focuses on the following
four topics: 1.
Analysis of Variance to compare three or more population means 2.
Inference for Regression, covering Simple Linear Regression and Multiple
Regression. 3.
Analysis of Two-Way Tables to study the relationship between two categorical variables. 4.
Nonparametric Statistics that do not require a Normal distribution of the
response variable. Required Materials 1.
Introduction to the Practice of Statistics, by David S. Moore and George P.
McCabe, 5th edition, Freeman, 2004. (Note – the 4th edition
may also be used). 2.
Scientific Calculator (around $10 to $15) that has some basic statistical
functions like mean and standard deviation (look for the following symbols: Course Website: http://www.stat.ufl.edu/~mripol Announcements for the course, and computer output to
supplement the examples done in class, will be linked from this page. There
will also be instructions on that website that will direct you to WebCT VISTA, an integrated, password
protected, Web based classroom management tool. In WebCT
you will be able to take the online quizzes, and check all your grades. Note:
The lectures for this class will NOT be available online. Online Quizzes - There
will be four online quizzes, administered through WebCT
VISTA. You will have three tries for each quiz (with questions randomly
generated) over a period of approximately 4 days. Each quiz will be worth 10
points, for a total of 40 points. Hopefully these quizzes will serve the
purpose of improving your grade in the class, as well as be an important tool
in learning the material for the course. More details on the WebCT quiz functions will be given in class. Quiz dates
will be announced in class. Suggested Homework Problems will appear on the website.
They will help you master the material but will not be collected. Projects - There will be two data analysis projects to be completed during the
semester. Each project will be worth 30 points, for a total of 60 points.
More details will be given in class.
Exams - There will be two exams given in class during the semester, plus one
during finals week, each worth 100 points, all in
multiple choice format. Students
are required to take the exam in the section they are registered for. All students must bring to the exam: their student ID number, picture
ID, a calculator, and pencils. In case of conflict or illness, if a student is unable to take an exam at the scheduled time, they
must get in touch with the instructor immediately, for any arrangements to be
made for a makeup. Each case will be reviewed individually. Valid and
detailed documentation is a prerequisite under such extenuating
circumstances. A grade of zero is the minimum punishment of any type of
dishonesty on an exam.
Course Policies: Email – will be answered within one working day in most
cases. Please be aware that statistical questions should be answered in person
(in class or during office hours) since they often require pictures and
formulas that make it very hard to communicate through email. Attendance – although not required, is very highly
recommended. This class is NOT offered online. If you miss a class for any
reason, it is your responsibility to get a copy of the notes and all
information given in class from another student. Additionally, during class
students should turn off their cellular phones and refrain from eating,
drinking, reading newspapers, doing homework and excessive talking. Instructor's Honor Code - We the members of the Academic Dishonesty - We adhere to the Grading – grades will be changed only when an error has been made.
Negotiation is not appropriate. Incompletes are only assigned when extraordinary circumstances,
arising after the date for dropping the course, prevent the student from
completing the course requirements. Having a failing grade in the course is
not a valid reason for requesting an Incomplete. Students with Disabilities - Students who require special
accommodations in class or during exams should follow the procedures outlined
by the Disability Resources Program
(http://www.dso.ufl.edu/drp/). Please see the instructor during office
hours early in the semester, to discuss your accommodation letter
confidentially. |
