Course Description:This course is designed to give students the chance to develop skills useful in statistical analysis of data produced in business, science, psychology, education and other areas. Students need to have completed Math 233 or an equivalent in the last 2 years in order to be prepared for this class. The student is expected to be responsible and able to work independently as well as in groups.

Course Objectives:As a student in this class you will learn skills useful in visualizing and interpreting data in a scientific way. Our text and my lectures will help you to learn, practice and master the following skills:

Statistical vocabulary; descriptive analysis and presentation of single and bi-variate data; probability; probability distributions with special emphasis on the normal distribution; sample variability; statistical inference with one and two populations; analysis of variance; linear correlation and regression analysis; an introduction to nonparametric statistics. This class must be added by Tuesday, June 17.Course Learning Outcomes: On completion of this course the student will be able to:

1. Describe and analyze data using descriptive statistics including histograms, frequency tables, stem-and-leaf diagrams, boxplots, mean, median, mode, and standard deviation.

2. Demonstrate proficiency with calculations of basic probabilities for simple events. 3. Identify the difference between discrete and continuous random variables. 4. Calculate probabilities using a normal probability table. 5. Interpret the Central Limit Theorem and apply the concept to examples. 6. Create and interpret confidence intervals estimates of population means and proportions 7. Employ hypothesis test procedures to test claims about single population means and

proportions, and two population means and proportions. 8. Employ linear correlation and regression to model simple linear relationships. 9. Utilize statistical software to analyze and interpret data.

10. Demonstrate a synthesis of concepts learned throughout the semester by a group project, which will require students to formulate a survey, collect data, analyze data, and derive inferences from the data.

Required Materials:Element of Statistics, Edition 2, Mario F. Triola; Scientific Calculator – TI 83 or 84; Pencils, Paper (for notes, tests and homework).

Attendance:Attendance is very important. 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. Please contact the instructor or the Admissions and Records Office if you can't continue. The refund deadline is Fri., 6/20. The NRS deadline is Thurs., 6/26. The W deadline is Wed., July 18.

Homework:You will be given daily assignments, which are meant to check your comprehension of definitions, and processes introduced from the chapter reading and class lecture. This work will be assigned daily in class and will be due the next day during the 1st 15 minutes of class. It will given a check if completed to the 80% level. The homework will account for 100 points of your final grade based upon the percentage of homeworks completed and turned in by the time which they are due. I will be generous and only consider 15 of your homework grades toward your final grade. I may also occasionally give class work that will be graded in addition to the daily work. Late work will not be accepted.

Some final pointers about homework: All work will be labeled with section and assignment and will be stapled in the upper left corner in sequential order. All problems must show the original problem, work and final answer to be considered complete. An answer only is never considered complete. My office hours and question time at the beginning of class are appropriate times for seeking help with homework. Remember, if you don't do your homework on your own and in a timely manner, you are hurting no one but yourself – homework is a very valuable learning tool, and tests will let me know how much work you are doing on your homework! No late assignments will be accepted! Do not ask, there is no circumstance that will make me change my mind!! You may turn an assignment in early (to me or by special arrangement through me) but after the first 15 minutes of class it is late.

Labs:We will have 6 to 10 labs. These labs are designed to reinforce concepts being taught in class and to incorporate and teach the use of a computer and the program Minitab, for statistical analysis. You must be present to receive full credit for the lab (25% of your grade will come from the in-class participation), although it can technically be done by following the lab instructions on your own time. The lab will be due by the end of class, 2 class days following the lab. Like every other part of my class, I will drop your lowest lab score. The labs will account for 100 points of your final grade, based upon your percentage scores.

Project:We will be doing a project as a class. I will have each of you contribute in bringing the project to fruition. The following schedule:

Due Thurs., 6/12 Three questions of interest concerning one of the following topics: politics, marriage and family, the environment.

Due Mon., 7/7 Return of 10 completed surveys assigned to youDue Thurs., 7/10 Electronic version of question asked to codeDue Thurs., 7/17 Analysis dueDue Thurs., 7/24 1 Page Paper with Appendix about finding

The project will be worth a total of 200 points and points will be assigned for each checkpoint in the project.

Quizzes:We will have a take home quiz each week (given on Thursday), except the week we have the midterm and the final. The lowest quiz score will be dropped. If you are not present to pick up a quiz, you must get one from a friend or make special arrangements to get one. I will not allow make-up of the quizzes for any reason. These quizzes will be given on the following dates and will be due on the Monday following during the 1st 15 minutes of class. Failure to turn the quiz in on time will result in a decrease of the percentage score possible to attain based upon 15 minute increments and a resulting 20% decrease in score. These quizzes will account for 300 points of your final grade and I will use your best 3 to compute your grade.

Quiz Schedule Thursday, June 19 (Due: Monday, June 23, by 1:15pm)Thursday, June 26 (Due: Monday, June 30, by 1:15pm)Thursday, July 10 (Due: Monday, July 14, by 1:15pm)Thursday, July 17 (Due: Monday, July 21, by 1:15pm)

Midterm:The midterm will be given in class on Thursday, July 5. It will cover material through the previous Thursday. It will be worth 350 points. You may make up an exam, but if I do not receive a message (846-4900x5129; no e-mails) at least 10 minutes prior to a test (12:50 am) detailing express conditions for missing the exam, which must be valid and verifiable. If you are unable to call please make sure that

someone does on your behalf. No make-up exams will be given except for a valid, verifiable reason and all must be made up within 1 week of the original exam.

You may bring an 8.5x11 piece of paper with notes on both sides. 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.

Final Exam:The final will be worth 350 points The final will cover material from the midterm through the last day of the class. The final will be Thursday, July 24 from 1:00 –3:50. For the final, I allow one 8.5X11 piece of paper with notes on both sides. The same rules apply as with the note cards that may be used for the midterm.

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.

Occupational/Vocational Statement:Occupational/Vocational Students - limited English skills will not be a barrier to admittance to and participation in Vocational Education Programs.

Additional Information:I reserve the right to make changes or additions to my syllabus at any time during the semester. I will notify you via class discussion of any changes or additions. The college catalogue overrides my syllabus at any time.

Welcome to Introduction to Statistics:Welcome to Math 5! I am excited about the coming session! I am here to help you learn about the exciting world of math 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). To be a successful mathematician it does take practice. You should plan to spend at least 2 hours outside of class, for every hour in class, studying your notes, text and doing problems. 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 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 summer session at Gavilan!
