COURSE DESCRIPTION:
A first course in descriptive statistics open to all majors covering data analysis, regression and
correlation, counting and probability, common probability distributions, sampling, confidence
intervals and one-sample hypothesis testing. Group activities, writing assignments and laboratory
activities may be required.
COURSE PREREQUISITES:
Placement into MTH243 or higher; or MTH105 or higher, with a grade of C or better; or equivalent
course as determined by instructor; or consent of instructor.
REQUIRED TEXT:
Triola, Mario F.,Elementary Statistics, 12th edition, Addison Wesley ©2014
or
Elementary Statistics, Custom Edition for Chemeketa Community College, Pearson ©2014
SUPPLEMENTS:
This course can be learned without reference to any specific technology and can be learned with only
a scientific calculator. However, because of the specific technology available to us, you should
become familiar with at least one of the following supplements.
The TI-83/84 plus calculators and the TI-Nspire have statistical functions that aid in the learning of
statistics. You will be allowed the use of a calculator when taking exams, but you won't have access
to any of the other technology supplements. For this reason, I recommend that you become familiar
with your calculator, knowing what it will do, and how to use it.
If you already have a graphing calculator, the TI-86 and the TI-89 can be updated with all the
statistical routines that are resident on the TI-83/84 plus calculator. See the instructor to download
the routines into your calculator.
·STATDISK:
This is an easy-to-use statistical software package developed specifically for use with
Elementary Statistics, and is included on the CD-ROM provided with new copies of the text.
References to STATDISK are integrated throughout the text. A separate STATDISK
manual/workbook is available as a supplement. The Appendix B data sets are included on the CDROM in a Minitab Format.
·Minitab:
There are references to Minitab throughout the text, and there is a separate Minitab
manual/workbook available as a supplement.
1
·Excel:
References to Excel are included throughout the text, and there is a separate Excel
manual/workbook available as a supplement. The Appendix B data sets are included on the CDROM in an Excel Format.
·Graphing
Calculator Manual for the TI-83 Plus, TI-84 Plus, Ti-89 and TI_Nspire: References
to TI graphing calculators appear throughout the text. I recommend this supplement because it shows
you how to access the statistical functions on your graphing calculator.
·Web
Site: You will be directed to a web site specifically designed for this text for some internet
projects. The address is http://www.awlonline.com/triola Many student resources are available there
·Videos,
Animations, etc: The videos are designed to supplement the sections in the book. The
videos feature professor and student interaction, and all technologies in the book are represented on
the videos. You have access to all of these at http://coursecompass.com If you purchase a new text at
Chemeketa’s bookstore, access to this product is included in the price. Also at that site is an
electronic version of the text.
Some of the above supplements are available in the Chemeketa library.
PERFORMANCE BASED LEARNER OUTCOMES:
Upon successful completion of the course, students should be able to:
1.
Use mathematical problem-solving techniques involving statistics. Techniques include the
use of graphical, symbolic, narrative, and tabular representations.
2
Create models of real world using statistics.
3.
Use inductive reasoning to develop mathematical conjectures involving statistics. Use
deductive reasoning to verify and apply mathematical arguments involving statistics.
4.
Make mathematical connections to, and solve problems from, other disciplines involving
representations of statistics.
5.
Use oral and written skills to individually and collaboratively communicate about
applications involving statistics.
6.
Use appropriate technology to enhance their mathematical thinking and understanding of
statistics and judge the reasonableness of their results.
7.
Do projects that encourage independent, non-trivial exploration and models using statistics.

Incomplete: (from college catalog) An ‘I” must be requested by the student, (there is a form that must be
signed by the student,) and is given at the instructor’s discretion when some essential
I/B
requirement of the course has not been completed, and additional time is granted for
I/C
completion of coursework. A contract will specify the length of additional time to
I/D
complete the course material (standard is one-term). If the contract is not fulfilled
I/F
then the “I” grade will revert to the specified letter grade. An “I” does not entitle a
student to satisfy a prerequisite requirement for another course.
For this class this means that you were unable to take the final exam due to reasons beyond
your control, you were passing the course, had attended regularly and discussed with me your
situation.
CLASS PROCEDURES:
Activities: You will be given credit for participating in group learning activities. If you do not
participate due to absence or unpreparedness, you will not receive credit that day.
Homework Assignments: You are encouraged to work together on homework. The following
procedure is required to earn the maximum credit for the homework problem sets.
Complete the problem set.
Self correct the odd problems. Answers are found in the back of your text.
Answers to the even numbered problems will be available on the internet at
http://faculty.chemeketa.edu/wbarber1/mth243/index.html and will be displayed in class
on the due date.
Show your corrections to each missed problem in red ink and write the number of missed
problems on the top of the page of your homework. If you don’t know the answer to a
problem, copy the answer on your paper using red ink.
Your homework will be evaluated on the following criteria:
All assigned problems are included
2 points
The above stated procedure is followed.
1 point
The homework is turned in on time.
2 points
Projects: You will be directed to some internet projects during the term. The purpose of these
assignments is for you to explore and understand the rich nature of statistics and its importance in
our world. You are encouraged to work together on projects.
Tests: Hour tests will be announced at least one week in advance. There will be Three exams plus
the final. If you know you will miss one, make arrangements in advance for making it up. You are
not allowed to work cooperatively on tests. All answers on exams must be your own work. You
will be allowed 1 page (single side) handwritten notes for each exam. You will be required to turn in
your notes with each exam.
3
Final: The final exam will be comprehensive. All answers on the final exam must be your own
work. You will be allowed 1 page (both sides) handwritten notes for the final exam.
INSTRUCTOR EXPECTATIONS:
• Attendance is expected.
• Come to class prepared to ask questions on the previous days' homework and the present days'
topic.
• You should expect to spend at least two hours a day, 4 days per week studying for this class.
• Label your homework with the page number, chapter, section number and problems assigned.
• Show your work in an organized manner.
• Turn in all assignments when due.
• I expect you to keep track of your own progress in this course.
• The maximum penalty for cheating is automatic failure of the course. Cheating one exams is,
but not limited to, copying answers from someone else’s paper, sharing your answers with
someone else, having more notes than allowed, etc.
SUPPLIES:
•A calculator is required. It should be capable of statistical computations. I recommend the TI-83 or
84 plus calculator. You may use it for homework problems and tests except where restricted. Keep
in mind that the calculator is a tool to be used toward understanding the mathematics. Use it freely
for computation and verification, but strive to understand the mathematical concepts of the course.
