REQUIRED TEXT:

Understandable Statistics Ninth Edition  by Brase/Brase

 

You can rent the textbook from the bookstore for $49.75 currently. If you want a rental and they are out, check back and they may get returns.

 

COUSE DESCRIPTION:

This course will cover data analysis including probability, distributions, sampling, hypothesis testing, confidence intervals, regression analysis, and nonparametric analysis.

 

PREREQUISITE:

A grade of C or better in Math 154A, Math 154AA, or equivalent; or a satisfactory score on Mathematics Assessment Test.

 

CALCULATOR:

A calculator with built-in one and two variable statistics functions is required for this class.  The TI-30X IIS is one such calculator that is inexpensive.

 

TUTORING:

Tutoring is available at no cost in A201 (Math Success Center) on a drop-in basis. Students will earn 0.5 point toward the total grade for every 10 hours in MSC or DRC. However, if any student misses more than two classes, no lab credit will be granted.

 

STUDENT LEARNING

OUTCOMES:

1. Design and implement an unbiased study that will produce sound statistical results.

2. Generate and interpret statistics graphs from data that arise from surveys and experiments.

3. Implement the rules of probability.

4. Apply confidence intervals and test hypotheses to make conclusions about

data that come from practical applications.

5. Perform regression analysis to make informed predictions about relationships

between quantitative variables.

Ø   student reports

Ø   Instructor Name: Shen

Ø   Click on your class: Math 201

Ø   Your secret number is on your Quiz #1

 

EXAM POLICY:

Grading will be based on progress towards the final answer, and the demonstration

of understanding of the concept that is being tested. The more you show me with

steps and detail, the better your chances for partial credit.  You provide me the

communication and detail in your answers; and I will give you the best grade I can

based on that communication and answer. You can use one page of notes, front and

back, for quizzes, exams and the final.

 

MAKE-UP POLICY:

For Chapter Exams, and the Final, make-up is possible if the absence is excused; there is a 10% penalty if the absence is not excused. The make-up test needs to be taken before the next class. The absence is excused for medical emergencies with the doctor’s note. You can take your test early if you know you are going to miss the class.

 

The first five minutes of each class, there will be a quiz that covers the main point from the previous lecture. Quizzes cannot be made up; however, the quiz with the lowest score will be dropped.

 

For Homework, you must show your work to get credit, half credit for

completion and half credit for selected problems. Homework will be accepted late up to one week after it is assigned for half credit. You can turn in your homework early if you know you are going to miss the class. You can consult a classmate, a tutor, your instructor, or anyone for assistance on the homework.

 

COMMUNICATION

POLICY:

You can communicate with me either by coming to class or office hours, sending

an e-mail, or calling on the phone. I will respond to your e-mails in a timely manner, and I will do my best to return your calls (you need to make sure to leave your number clearly). If you miss the class, it is your responsibility to pick up the class handouts or obtain the information either from your classmates or from me during the office hours.

 

I have students work together to help each other. Please feel free to ask me directly if you like to work with me one-on-one.

 

·   Please see me if you do not understand my policies.

 

·   Since English is my secondary language, please be sure to ask me if you have any difficulty understanding math due to my accent. I will be happy to clarify.

 

LEARNING

DISABILITIES:

If you have a certified learning disability, be sure to discuss your special needs with me during the first week of class. Learning disabilities will be        accommodated.

 

REGISTRATION:

·   You must register for this class at the Office of Admissions and Records.

·    The last day to drop the class with no record is Friday, May 1.

·    The last day to declare CR/No Credit is Friday, May 1.

·    The last day to drop the class for a “W’ grade is Friday, May 22.

·    After May 22, if you are enrolled, you will receive some kind of grade.

·    It is your responsibility to drop the class in order to avoid a grade. You can choose Credit/Non-Credit for the class before the date specified on the schedule. I will drop a student from the class if the student misses more than four classes and is unable to keep up with the learning.

 

FINANCIAL

ASSISTANCE:

If you need help paying for your books or other expenses, call our financial aid

officer, America Ramirez, at 541-4660 x236, email her at Ramirez@ltcc.edu, or

drop by A100.

Tentative Lecture Schedule for Math 201

 

Be sure to use class time, office hours, and the MSC to get all of your questions answered.

For your homework, make sure you separate each section on the different pages and separate each problem on the different lines. There will be one point deduction for each section if the grader cannot read your answers. ALWAYS WRITE THE HOMEWORK # AND SECTION #s FOR EACH HOMEWORK.
