Course Description:
An introduction to modern methods of descriptive statistics, including collection and presentation of data;
measures of central tendency and dispersion; probability; sampling distributions; hypothesis testing and
statistical inference; linear regression and correlation; use of microcomputers for statistical calculations.
Illustrations taken from the fields of business, economics, medicine, engineering, education, psychology,
sociology and from culturally diverse situations.
Student Learning Outcomes:
Upon completion of the course, the student will be able to:
1. Distinguish between quantitative and qualitative data; sample and population; descriptive statistics and
inferential statistics.
2. Read a graph and conclude what information the graph is conveying about the data.
3. Calculate measures of central tendency, dispersion and relative standing and use these measures to solve
application problems.
4. Compute basic probabilities.
5. Define discrete probability distributions and use such distributions to solve application problems.
6. Define continuous probability distributions and use such distributions to solve application problems.
7. Define sampling distributions, state the Central Limit Theorem and use sampling distributions and the
Central Limit Theorem to solve application problems.
8. Use confidence intervals to estimate population parameters, or the difference between two population
parameters, using the appropriate formula and then interpret the result.
9. Determine the sample size required to estimate a population parameter.
10. Design, set up, and evaluate the results of hypothesis tests.
11. Compare and contrast the use of confidence intervals and hypothesis tests to make inferences about
population parameters.
12. Solve application problems utilizing techniques of regression and correlation.
13. Use analysis of variance to make inferences about more than two population means.
14. Solve application problems using categorical data analysis.
15. Demonstrate statistical understanding of inference by participating in a cooperative project.
16. Demonstrate proficiency in the use of the computer as a tool for doing statistics
17. Apply statistical methods to situations in a culturally diverse society.
18. Discuss mathematical problems and write solutions in accurate mathematical language and notation.
19. Interpret mathematical solutions.
Required Materials:
Understandable Statistics, Ed. 9, Brase & Brase; Access to Web Assign; TI-83 or TI-84 Series Calculator;
Pencils, Paper (for notes, quizzes and homework); a 3-ring binder (1.5in. or larger) is also a good idea.

Attendance:
Attendance is very important. You are expected to attend every class meeting. Class sessions will cover
material from your book, but may also give a different perspective on the material in your book. A student
who stops attending is not automatically dropped from class, although I reserve the right to drop a student
who misses 3 class meetings. Students on the final grade roster who have not dropped, and who do not
show up for the final exam, automatically receive an F in the course – it is your responsibility to drop
yourself from the class if you don’t wish to continue. Please contact the instructor or the Admissions and
Records Office if you can't continue. The refund deadline is Fri., 10/1. The NRS deadline is Fri., 10/15.
The W deadline is Fri., 11/11.
Web Assign Homework:
We will be using Web Assign to do our homework on-line. I have already entered my entire roster,
including those on the waitlist into my Web Assign class. You will go to the Web Assign website at
http://www.webassign.net/login.html. Once there, you will need your username, school name and
password. Right now, everyone’s username is set up as lastname.firstname (all in lower case, as it appears
in Foothill records). The school name is foothill. Everyone currently has the same password and it is
foothillMath10. You should change your password once you log in. You will either have purchased an
access code at the bookstore with your text or you will have to purchase it once the grace-period expires on
Web Assign. The Web Assign account should come with a e-text, and there may be an option to have the
text or not (I am not sure, this is new to me). You may also be able to upgrade your Web Assign account to
have more tools available for study. These options are at your discretion; I will make no requirements
beyond the basic ability to do the homework exercises assigned through the service. I will use your average
grade from your Web Assign homeworks to compute your homework score. I will drop the lowest 20% of
your grades and take the average percent of 75 points using the remaining 80%. Pay attention to due dates
as no late assignments will be accepted!
Labs:
Labs will be assigned as we encounter topics of discussion that will benefit from the use of the computer
and calculator. The purpose of labs is to familiarize you with the use of Excel and the TI calculator in
capturing data, exploratory data analysis and in statistical analysis. Some of the labs that we will have will
involve: familiarization with the PMSE, random number generation, graphing/visualization techniques,
summary statistics, confidence intervals, the Central Limit Theorem, t-tests, z-tests, correlation and
regression, χ2 analysis, and ANOVA. We may have one lab per week. I’ll grade each lab based upon the
completion of the requirements, the write-up presented and understanding of concepts. Each lab will
receive a percentage. The lowest 20% of the lab scores will be dropped. The highest 80% of the labs will
be averaged and the average percentage of 75 points will account for your lab portion of the class. (This
portion of our class could satisfy the TBA requirement if necessary.) I will not accept late work for ANY reason. Labs
are due during the 1st 10 minutes of class on the due date indicated on the assignment.
Project:
We will be doing a project as groups in class. Most of the project will be done outside of class, but we will
be discussing pertinent topics in class. Labs are designed to aid in the completion of the project, so those
are of great importance. The project will be worth a total of 150 points, with each portion assigned a
percentage as indicated below. The following is the tentative schedule of the check points:
Week 1

errors)
1-2 page paper with an appendix. Paper will discuss purpose, original hypotheses, findings
(referencing appendix and statistical finding from analysis), conclude with success/failure and
hypothesized reasons for success failure and suggestions for future investigation on this same
topic. The appendix will include: survey questions, EDA, computer output used in analysis
including 2-way tables, summary statistics and any hand calculations, all hypothesis tests will
be clearly out-lined and will include H0 & HA and refer to computer calculations for final
conclusions (which will also be stated in proper language).
In-Class discussion of projects & Grading of fellow group members due (5% based on grade given
by other members of your group & 5% based on contribution in class)
Tests:
We will have three regular exams at approximately three-week intervals. Each will be recorded as a
percentage. Your lowest one will be dropped. Your final test grade will be an average earned percentage
of the 300 points allotted for test points. Tests can not be taken late for any reason (you have one opportunity to
miss a test and not have it count against you – a missed test will be dropped and therefore have no effect on your grade) .
You may bring a 5X8 note card to each exam. The card may contain steps for doing problems, partial
definitions and portions of a problem where you know you always have difficulty, but it may never contain
a complete problem. You must staple the note card to the back of your test.
Tentative Exam Schedule

You may bring a 5X8 note card to each exam. The card may contain steps for doing problems, partial
definitions and portions of a problem where you know you always have difficulty, but it may never contain
a complete problem. Failure to comply to these specifications can result in a zero, and is considered
cheating. You must staple the note card to the back of your test.
Final Exam:
The final will be worth 400 points This exam will have a take-home portion covering cumulative material
and an in-class portion covering new material. The final will be Fri., Dec. 10, 2010 at 2-4pm.

Class Rules:
The rules of my classroom are pretty basic – Be respectful of others. This means that you should not
interfere with anyone else's ability to learn. Ways in which you may interfere include talking during lecture,
not participating in group activities, using electronic devices for music/texting/gaming during class, making
any kind of disruptive noise during class, coming to class late and not making an effort to be as unobtrusive
as possible, wearing a hat in class, etc. I will follow the policies outlined in the college catalogue in dealing

with violations of the class rules. Note: If I see your cell phone out on a consistent basis and see you
disrupting others through its use or if you are not focusing, you will be warned and following a warning
asked to leave the classroom! Cell phones are not allowed out during quizzes and tests! Having a phone
out for any reason, without expression consent will be considered cheating (see below)! I know there are
unexpected emergencies as well as times when we are expecting an important phone call, so I if the need
arises, please use your phone discreetly. Discreet phone use includes keeping it on silent mode and preferably in your
pocket. Discreet use also means waiting to answer the phone until you’ve stepped outside, or if it can’t be put off, answering with a
quick whispered, “Hello, hold on for a second.” Just so you know in advance, my cell phone is always on my desk because I use it as
a time keeping device for breaks and end of class, and you can be assured that I will not be answering it unless it is an emergency –
and I do have children that will from time to time be with a babysitter, so those can arise!
Student Honesty:
When doing homework I encourage students to work together and help one another. Students are expected
to do their own work on tests and quizzes. I allow students to bring a 5x8 note card filled with notes to each
exam. Cheating will not be tolerated! Talking to anyone but me, helping another student during an
tests/quizzes, bringing more notes than authorized, copying information from another person's test or quiz,
using external sources of information for which you were not explicitly given permission to use (including any
calculating device not explicitly stated as appropriate, phones and pda’s included) is considered cheating. Students caught
participating in such activities will receive a zero on a quiz, violations on an exam can also result in a drop
from the course or a grade of an F in the course (regardless of class standing)! Cheating incidents will also
be reported to the Dean of Students and further action could be taken in accordance with school policy.
Student Grievances:
Please refer to the grievance policy in the college catalog if you have any questions.
Student Special Services:
Students requiring special services or arrangements because of hearing, visual, or other disabilities should
contact their instructor, counselor, advisor, or Disabled Student Services Office by the end of their first
week of instruction. I encourage all students with special needs to contact me after the first class meeting to
arrange for any classroom assistance.
Additional Information:
I reserve the right to make changes or additions to my syllabus at any time during the quarter. I will notify
you via class discussion of any changes or additions. The college catalogue overrides my syllabus at any
time.
You may find that you need additional help outside of class. I strongly urge every student to begin getting
extra support from the beginning. Some additional resources include, tutoring offered in the PSME (Math)
Center in Rm 4215, Tutorial Center in the Portable Village in Lot 5, private tutors and of course my help
and your class mates' help. There will be a schedule posted for the tutoring and computer labs as soon as it
is presented to me.
Welcome to Statistics:
Welcome to Math 10! I am excited about the coming quarter! I am here to help you learn about the exciting
world of statistics and if there is anything that you think will make your learning experience more
rewarding, please let me know (please do not make the mistake that this is an invitation for you to tell me how to run my class,
this is merely on a one on one office hour basis). By now I expect that you realize that in order to be a successful
mathematician it does take practice, but I will remind you! You should plan to spend at least 2 hours
outside of class, for every hour in class, studying your notes, text and doing problems (this means at least 10
hours per week; it is not wise to assume it will all happen on the weekend) . I would like to stress that any math class
goes very quickly – please stay abreast of your work and don't neglect your study. Class participation and
study/project groups are very important as well! We will have occasional class time for group study, but
you should get the names and numbers of at least two fellow class members to call in case you miss a class
or need to ask a quick question. Have a great fall quarter at Foothill!
