2. General Course Information
|
This course satisfies
General Education Credits in the Mathematical Sciences. Students learn how
to summarize data and how to make appropriate decisions based on data. This
course has a General Education Category of M.
Course Description
STA 2023 is an introductory course that assumes no prior knowledge of
statistics but does assume some knowledge of high school algebra. Basic
statistical concepts and methods are presented in a manner that emphasizes
understanding the principles of data collection and analysis rather than
theory. Much of the course will be devoted to discussions of how statistics
is commonly used in the real world. There are two major parts to this
course:
I Data –
which includes graphical and numerical summaries to describe the
distribution of a variable, or the relationship between two variables
(chapters 1, 2 and 3, approximately 4 weeks), and data production to learn
how to design good surveys and experiments, collect data from samples that
are representative of the whole population, and avoid common sources of
biases (chapter 4, 1 week.)
II Probability and Inference –
using the language of probability and the properties of numerical summaries
computed from a random samples (chapters 5 and 6, 3 weeks), we learn to
draw conclusions about the population of interest, based on our random
sample, and attach a measure of reliability to them (chapters 7, 8, 9
approximately 8 weeks).
Course Objective
The primary goal of the course is to help students understand how the
process of posing a question, collecting data relevant to that question,
analyzing data, and interpreting data can help them find answers to real
problems from their world.
General Education Objective
(Mathematics)
Courses in mathematics provide instruction
in computational strategies in fundamental mathematics including at least
one of the following: solving equations and inequalities, logic,
statistics, algebra, trigonometry, inductive and deductive reasoning.
These courses include reasoning in abstract mathematical systems,
formulating mathematical models and arguments, using mathematical models to
solve problems and applying mathematical concepts effectively to real-world
situations.
In this course, this objective will
be met by . . .
During the semester the students will be
given an introduction to the three main aspects of statistics: design (of
experiments/surveys), description (of data collected) and inference
(the extension of conclusions from the data gathered in the sample to the
larger population). These concepts will be presented through lectures three
times a week and lab once a week. They will also learn about the normal and
binomial distributions as well as the methodology of confidence intervals
and significance tests. From the methods that they learn in class they will
be able to critique real world surveys and experiments, interpret graphs in
newspapers and magazines as well as conduct basic statistical inference for
one or two groups.
General Education Student Learning
Outcomes (SLOs)
Content: Students demonstrate
competence in the terminology, concepts, methodologies and theories used
within the discipline.
Communication: Students communicate
knowledge, ideas, and reasoning clearly and effectively in written or oral
forms appropriate to the discipline.
Critical Thinking: Students analyze
information carefully and logically from multiple perspectives, using
discipline specific methods and develop reasoned solutions to the problems.
In this course, these SLOs will be
met by . . .
Content: Students will learn
critical terminology, concepts, methods, and theories during lecture. These
concepts will include terminology to describe one and two samples, discuss
surveys/experiments, basic probability theory, sampling distributions, and
one and two group inference. The students will be assessed on these terms
and concepts during the weekly quizzes and the three exams. Students will
also demonstrate their competence in identifying the appropriate formulas
to use for each situation and using those formulas correctly.
Communication: The students will
use verbal and written communication to discuss central statistical
concepts in their weekly labs. These concepts include description of data
sets, sampling methods and interpretations of inference methodology.
Critical Thinking: The students will be
asked to critically think about trustworthiness of surveys and experiments
presented in the media. Additionally, students will learn how to conduct
significance tests, a statistical method to logically determine if there is
enough evidence for a hypothesis. Students will learn how to state the null
and alternative hypotheses (different perspectives) and then to use the
data collected to determine if there is enough evidence to support the
alternative hypothesis using methods central to the field of statistics.
The students will be tested on these concepts in lab, quiz and on two of
the exams.

5. Lectures
|
Live Lectures
Live lectures are taught in a large
lecture hall that should accommodate everyone who wants to come. Everyone is welcome to attend these live
lectures, even those who are registered for a Web class. Lectures will also
be taught in a smaller classroom where they will be videotaped. The videotaped lectures will be available
to view online through the course webpage in e-learning the same day,
before 4pm (usually as soon as the lecture is recorded). No one is
registered for this class, but everyone is welcome to attend. However, this room only seats around 25
students, so come early if you are interested.
Online Lectures Links to the videotaped lectures will be found at the course website. You can watch the videos at home – they work best with Internet Explorer. IMPORTANT - We cannot guarantee that the online lectures will work well for each of you. Be prepared to attend the live lectures if that turns out to be the case. Some students do not have the discipline to watch and really pay attention to the online lectures, or the videos are too slow. Please remember that everyone is welcome to attend the live lectures, regardless of which section they are registered for. If you’re having technical problems with the online lectures please contact the UF computer Help Desk for assistance: call (352) 392-HELP (4357) or email: helpdesk@ufl.edu
|
6.
Weekly Lab Sessions in CBD220
|
Students are required to
attend Lab once a week, according to the section for which they are
registered. In Lab, groups of around 40 students will meet with a TA to
work on a simple, hands-on activity related to the material being covered
in class. All Labs meet in Classroom Building 105, room 220 (CBD 220). This
building is located half a block north of University Avenue, across from
Library West. Worksheets with instructions for each Lab are included in the
Lab Workbook. Students must bring these worksheets to Lab each week. The
worksheets must be turned in to the TA before leaving Lab that day. They
will be graded on a scale of 6 points.
Lab
Attendance and Policies:
·
Go to the right section. Students
must attend the section they are registered for - you will get no credit
for your work if you attend a different section.
·
Be on time. Students
must be on time for Labs, and will not be allowed to enter if they are more
than five minutes late. Late students would disrupt the activity, and
create problems for the rest of the students and the TA, so it will not be
tolerated.
·
Be prepared. Students
must come prepared to Lab, having watched the lectures that cover material
relevant to the Lab's activity.
·
Bring the Worksheet. Students
must bring the Lab Worksheet to Lab with them - you will get no credit for
hand written labs.
·
No Makeups. Students
will not be permitted to make up any Labs that they have missed, regardless
of the reason. Instead, we will drop the lowest three grades for all labs
and quizzes combined.
NOTE: If
you are registered for a lab section that conflicts with another class, or
with several night assembly exams for other classes, you MUST CHANGE LAB
SECTIONS IMMEDIATELY. STA 2023 Labs will never meet on the days we have an
exam. There are usually plenty of opportunities to change sections during
Drop/Add period. After Drop/Add is over, you will need to contact the Lab
Coordinator to see if any changes are possible - see the top of this
Handbook for the Lab Coordinator's contact information.
|
7.
Weekly Online Quizzes through e-learning
|
·
When? We will have online
quizzes every week, unless there are exams or holidays. The quizzes are
available online, through e-Learning, over a period of several days – the
exact details will be announced in class and posted in the announcement
page.
·
Where?
You can do the quizzes from any computer that has internet access.
·
Material.
These quizzes will cover the material taught in class the previous week,
and are designed primarily to encourage you to keep up with the lectures,
particularly if you choose to watch them on the web at your own pace.
·
Three tries. You
will be allowed three attempts for each quiz – each randomly generated, so
the questions won't be identical. The highest grade will be recorded.
·
Getting help. You
are allowed to ask the TA's and the instructor questions about submitted
attempts on the quiz only. For example, you can take the quiz one time,
submit the quiz for grading, and then print out the quiz. You can then
bring this printout with you to the tutoring room, where the TA's can help
understand what you did wrong. You can then go and try attempt 2 on your
own.
·
No makeups. There
will be no makeup quizzes for any reason. Instead, we will drop the lowest
three grades for all labs and quizzes combined.
·
Do well. Given
all these opportunities, all students should do extremely well on the
quizzes. Hopefully they 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. You can also print your quizzes and use them to study for exams.
·
Problems?
Pop-ups. If
you click on the quiz and nothing happens, you need to allow pop-ups for
this website. Firewalls may also interfere with the quizzes.
Computer
crashes in the middle of the quiz or electricity goes out?
Restart the computer and log in again into e-Learning – it should let you
continue the quiz. If for some reason, the system does not let you back
into the quiz, email the instructor at mripol@stat.ufl.edu.
Time
Expired. If e-Learning gives you nasty messages about your time
being expired, ignore them, finish the quiz and submit it.
Technical
Problems. If you have technical problems with e-Learning, contact
the CIRCA help desk at 392-HELP. If you are having trouble with the quizzes
from your computer at home, and the quiz is about to close, the easiest
thing to do is try from another computer.
|
8.
Exams
|
There
will be three assembly exams, each worth 100 points. The two midterms are
given at night, and the last one during final exam week. Each exam consists
of 33 multiple choice questions, each worth 3 points apiece. This will
total 99 points. You can earn the remaining 1 point by bringing a picture
ID to the exam and by bubbling in your name, UF ID# and test code (listed
on the front page of the exam) correctly. Exams will cover a larger amount
of material that the quizzes and will also place more emphasis in the
understanding of concepts and ideas behind the formulas.
Room assignments for each exam will
be announced in class and on the website. The class will be divided up by
sections. Bring to the exam your UFID
number, a picture ID, no.2 pencils and eraser for completing the bubble
sheets, and a scientific calculator. Graphing calculators may be used during the exam, but only for
programs native to the calculator when you purchased it. Notes for the
course and formulas for the course should not be typed into your
calculator. Accessing notes and formulas from the course on your calculator
during the exam is cheating. Academic
dishonesty on any exam will result in a minimum penalty of a grade
of zero on that exam.
Makeup
Exam Policy
·
In case of conflict with a class: You
must attend the regular exam. Assembly exams have priority over
regularly scheduled classes. The instructor for the other class must allow
you to make up any work you miss because of an assembly exam - contact them
early to make arrangements. This is a University of Florida policy, as
stated on the Registrar's website http://www.registrar.ufl.edu/currents/finalexams.html .
·
In case of conflict with another exam: You
must attend the regular exam unless the other exam is also an assembly
exam, and the course number is higher than 2023. Assembly exams have
priority over time-of-class exams. If you have two assembly exams scheduled
for the same day and time, the course with the higher number has priority.
This is a University of Florida policy, as stated on the Registrar's
website. If you need to schedule a makeup, contact the instructor through
email, in person during office hours, or through the phone (information
appears at the top of this page). Makeup arrangements must be made at least
ONE WEEK prior to the regularly scheduled exam.
·
In case of sudden illness or emergency:
Contact the instructor as soon as you realize you will be
unable to take the test at the scheduled time. Each case will be reviewed
individually. Valid and detailed documentation is a prerequisite for
scheduling a makeup exam under such extenuating circumstances. The
instructor must be contacted PRIOR to the time of the regularly
scheduled exam.
·
Format of Makeup Exams
will not necessarily be multiple choice although
it will cover the same material as the regular exam.
·
Travel Plans. Traveling,
in general, is not a valid reason to request a makeup exam. Do not buy
plane tickets assuming the instructor will then have to make other
arrangements for your exam.
|
9.
Lecture Notes
|
The
notes in the Lab Workbook will be used in class. When you are following the
lectures, whether live or on the web, you should always have the lecture
notes in front of you. The instructor will go over the definitions and
theory, and work out the examples on the spaces provided.
|
10. Homework
and Practice Questions
|
·
Suggested Homework Problems
from the text, by section, can be found on the course webpage in
e-Learning. These problems are assigned to help you master the material and
will not be collected. You can get help with these problems from the tutors
in the Tutoring Room. Doing the homework is essential step in succeeding in
this class.
·
Answers to
odd numbered homework problems are available in the back of the
text. Answers to all of the problems are available in the Instructor's
Guide – copies of this are available in the Tutoring Room, and on
reserve at Marston Science Library.
|
11.
Minitab Statistical Computing Package
|
Minitab is a very easy to use and powerful statistical
computing package. We will use Minitab in several of our Labs - the
teaching assistant will give you directions on how to use it. You can also
use Minitab to solve some of the homework problems assigned from the book.
The data sets for most homework problems are included in the data disk that
comes with the textbook.
Minitab
is available free through UF
Apps and at all the PC’s (not Macs) on the Computer Labs on campus.
You can also buy it for your home computer (or download the demo version -
free for 30 days) at the Minitab website at www.minitab.com,
or rent a copy of the software for a semester at www.e-academy.com/minitab.
|
12.
Tutoring Room
|
The
TA's for the class will be available to answer questions about the material
covered in class, homework problems, etc, in the
Tutoring Room located in Griffin Floyd 104. It will be open approximately
40 hours a week – the schedule for this semester will be posted in
e-learning. There is no need to make an appointment, just go whenever it is
convenient for you and the TA on duty will help answer your questions.

Course Policies
|
- Privacy Policies: Student records
are confidential. Only information designated “UF directory
information” may be released without your written consent. UF views
each student as the primary contact for all communication. If your
parents contact me about your grade, attendance or other information
that is not “UF directory information”. I will ask them to contact
you.
·
Email: Email
relating to information about the class should be sent to your TA (see
email addresses on first section of this syllabus) or to the instructor at
mripol@stat.ufl.edu. Your message will be answered within two working days,
in most cases. However, we ask you to please refer to this Syllabus, the
Announcement Page and the course website to try to find the answers for
yourself. Questions regarding the material covered in class, homework
problems, or Lab should be asked in person, in the Tutoring Room, in Lab or
in class. Statistical questions often require formulas or pictures, which
can make it very hard to communicate by email. Emails should include your
full name, and section number. If you are referring to a quiz, refer to it
by quiz number, attempt number and question number.
·
Instructor's Honor Code: We
the members of the University of Florida community pledge to hold ourselves
and our peers to the highest standards of honesty and integrity.
·
Academic Dishonesty: We
adhere to the University of Florida rules and guidelines for handling
instances of academic dishonesty. Please refer to the Office for Student Services
for detailed information about the current policies.
- Students with Disabilities: Students with disabilities requesting accommodations
should first register with the Disability Resource Center
(352-392-8565, www.dso.ufl.edu/drc/)
by providing appropriate documentation. Once registered, students will
receive an accommodation letter which must be presented to the
instructor when requesting accommodations. Students with disabilities
should follow this procedure as early as possible in the semester. This letter must be discussed with
the course coordinator directly, not with the lab TA, for
accommodations on exams to be made.
·
Class Attendance and Behavior: Attendance
to class is not mandatory, since you will be able to watch the lectures
online. Attendance to Lab, however, is mandatory, and you are required to
attend the Lab section for which you are registered. For both Labs and
lectures, we ask that you arrive on time, and to behave in a respectful
manner towards the instructors and your fellow students. In fact, no one
will be allowed in Lab if they are more than five minutes late. Please turn
your off cellular phones and refrain from eating, drinking, reading newspapers,
doing homework for other classes, and excessive talking.
·
Makeup Quizzes and Labs: There
will be NO makeup labs or quizzes under any circumstances - instead, we
will drop the lowest three grades for all labs and quizzes combined. These
three drops are meant to allow for missed labs or quizzes due to illness,
personal or family emergency, personal or University sanctioned travel,
religious observance, tardiness, laziness, and all other reasons. Do not
abuse your drops - you never know if you will need them later.
·
Makeup Exams: See
the section on Exams for exam makeup policy.
·
Grading: Grades
will be changed only when an error has been made; negotiation is not
appropriate.
·
Incompletes are
only assigned when extraordinary circumstances (such as an accident, or
extended hospitalization), 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.
