I. Outline of the Course

 

Instructor: Hokwon A. Cho, Ph.D., Associate Professor, CBC B-506, Office phone: 895-0393 (Math. Sci. dept. office: 895-3567), E-mail: cho@unlv.nevada.edu.

Class Time and Location: M,W 8:30 a.m. - 9:45 a.m., CBC C-116.

Office Hours: M,W 10:00 a.m. - 12:00 p.m., R 10:00 a.m. - 12:00 p.m., or by appointment, or by appointment.

Textbook: The Basic Practice of Statistics, 4th edition, David Moore, published by Freeman.

Scope of Course:

This is an introductory course in Statistics and probability. We study the statistical methods for data analysis. The emphasis will be on statistical thinking and real data analysis.  We will cover first three parts I-III (Chapters 1-22) plus chapter 23 in the text at minimum, but skip Chapter 7 and certain sections of other chapters. Broadly speaking, the topics to be covered are:

 

1)       Data & Descriptive statistics – Data & variables, graphical representation, exploring relationships.

2)       Sampling distributions & Probability – Normal distribution, Sampling, general rules of probability, binomial distributions.

3)       Basic statistical inference – Confidence Intervals, tests of significance, estimating population means and proportions.

4)       Categorical data – Chi-square test.

 

The statistical packages MINITAB (or any other kinds) will be used if available and necessary.

 

Homework, Quiz & Worksheet: Homework will be assigned every week and may not be collected. Possibly 15-min quizzes or worksheets will replace with the homework collection. Homework solutions will be posted on the course web site or e-mailed to you. No late homework will be accepted unless arranged with the instructor in advance.

 

Grading: The course grade is based on the followings: 

      Homework & assignments - 20%, Two tests (in class) - 25% each, Final Exam - 30%.

      

Exams: There will be two tests and a final examination. Two tests are most likely on 6th week and 11th week during the semester.  Final Exam: Please refer the course syllabus or Lecture & HW schedule.

      No makeup tests will be given except for documented medical reasons or prior permission from the instructor.

III. Bulletin Board

 

1. Final Exam is scheduled to be Wed. 8AM-10AM, May 14.

     Bring (1) Textbook, (2) Calculator and (3) Formulae Sheet.

 

The final exam is comprehensive, but to reduce your study load, I gave you a wrap-up in the class for your final preparation. Here are the four parts to focus for your study:

1) Sampling & Sampling distribution - Chaps (8) and 11. [Focus more on Ch. 11]
    (sampling distribution of the mean, standard error, central limit theorem, law of large numbers, etc.)
2) Probability & Binomial - Chaps 10,12 & 13
    (intersection, union, null set, Venn diagram, independence, disjoint/mutually exclusive event, binomial random variable and its distribution, normal approximation, etc.)
3) Confidence Intervals - Chaps 14, 18 & 20
    (constructing an interval for the sample mean using z, t and sample proportion, respectively.)
4)  Testing Hypothesis - Chaps 15, 16, 23 & Chi-square
    (type I error, type II error, p-value, testing: about the sample mean using z, t and sample proportion, respectively. For categorical data - there are two types of chi-square test -> you got to know!)

Please be confident about concepts and computations.  :-) Truly I wish you a best luck!  See you at 8AM Wednesday (14th) morning.

 

IV. CD ROM & Other Resources

 

Explore Student CD ROM to know how to use it. Be familiar with 7 parts of resources:

 

o        Statistical applets – You can choose one of 16 applets to help your understanding the concepts.

o        Self quizzes – Multiple-choice problems are designed to test your understanding for each chapter with automatic feedback. No penalty will be given!

o        Data sets - Data set files are stored according to your statistical analysis software and your computer's operating system

o        Tables & formulas - Various formulas, normal probability tables and random digit table are given for your convenience

o        Companion chapters

Tips for Successful Completion

 

(1)     DON’T’ BE ABSENT – Attending every class makes a BIG difference! Classroom is also cool! 

(2)     Make every Friday/Saturday Statistics day!

(3)     Practice problems and the homework assignments everyday.

(4)     READING your textbook until you understand clearly and DO NOT TAKE A BREAK until you finish at least 10 problems in each chapter.  Be sure to do self-check. If you make wrong answers, keep correcting until you get right answers.

(5)     Feel free to ask your instructor (DR. “JOE”) or others immediately whenever you have questions or stuck. (Just email me or call at 895-0393)
