Statistics 2 is an introductory statistics course designed primarily for humanities and social science students. It is not very mathematical. Neither linear algebra nor calculus is required. However, you need to be comfortable with math at the level of high-school algebra (e.g., equation of a straight line, plotting points, taking powers and roots, percentages). The emphasis of the course is critical thinking about numerical evidence. Topics include descriptive statistics, correlation and regression, elements of probability, elementary symbolic logic, chance variability, random variables, expectation, standard error, sampling, and hypothesis tests, confidence intervals, experiments and observational studies, as well as common techniques of presenting data in misleading ways.
The course uses the internet to distribute information and provide interactive exercises and examples. Assignments, the text book, and scores on assignments and exams are online. You will need to use a recent version of a web browser such as Netscape 4.78 or Internet Explorer 5.0 to take the class. Netscape 6.0 and 6.1 will not work with these materials, nor will the AOL browser.
To add the course, get on the telebears waiting list, attend the section you would like to be in, and submit the first assignment on time.
Required Text: SticiGui Online Text. The online version is free. A printed copy can be ordered from Atomic Dog Publishing for $32 plus shipping (when I last checked, the shipping cost to Berkeley was $4.22 ground, $6.08 3-day, $7.19 second-day, $16.45 overnight). The course registration ID to use on the Atomic Dog website is 2015573101080. The printed copy does not have all the functionality of the online version. You will still need to have internet access to read the online text and to do the problem sets. Printing the book from the website yourself is a violation of copyright---don't do it. Moreover, if you figure that it will cost you about $0.05 per page to print, it won't save you much either---the book is about 400 pages long.
Recommended Texts:
Midterm: There will be one midterm, on Thursday, 11 October, during class. No alternate time will be offered; don't ask. Practice materials are available online. The exam is multiple choice, and you must bring a scantron form (100 question form), a number 2 pencil, and a photo ID. You may bring a calculator if you wish.
Final Exam: Group 5, Thursday 12/13/01, 12:30-3:30pm. Room will be announced. No alternate time will be offered; don't ask. If you cannot attend the final, do not take the class. The final is cumulative. Practice materials are available online. The exam is multiple choice, and you must bring a scantron form (100 question form), a number 2 pencil, and a photo ID. You may bring a calculator if you wish.
Homework is due as posted online. Check due dates frequently. No late homework will be accepted, for any reason, including, but not limited to, internet congestion, system crashes, natural disasters, theft, and your pet's dietary idiosyncrasies. Don't ask. The longer you wait to do the homework, the larger the risk that server or internet traffic will delay your submission. The four lowest homework scores are dropped, to allow for the possibility that technical problems prevent you from submitting homework on time.
Grading is based on the average of homework (dropping the four lowest scores), midterm, and final, with equal weight, or the final by itself, if the final grade is higher. Sometimes I subtract "demerits" for violating class policy. Demerits are subtracted from the course grade. Sometimes I offer extra credit; extra credit is added to the course grade. Grades will not be "curved," so you are not in competition with anyone else. My usual grading scheme is approximately as follows, but it can vary:
99+ | 93-98 | 90-92 | 87-89 | 83-86 | 80-82 | 77-79 | 73-76 | 70-72 | 67-69 | 63-66 | 60-62 | <60 |
A+ | A | A- | B+ | B | B- | C+ | C | C- | D+ | D | D- | F |
It is possible for everyone to make an A (or an F). Grades on assignments and exams and the course grade will be available online. Sending email with questions about the grading scheme will result in lower grades.
Do the reading assignment before lectures. You will get more from both the text and the lectures. Try to solve all exercises in each chapter: some show up on exams. Read all homework and exam questions carefully, and take them literally--don't try to second-guess what is meant. Come to office hours. Check the announcements at least twice a week.
Come to class: even though attendance at lectures is not required, things happen in class that are not in the book and that are not announced on the website. You will miss out if you don't come.
Most general questions about the course have answers in this page, the syllabus, or the class announcements. Send me email only to report a typo in the text or a bug in the text. I will reduce your grade if you send me email for any other reason. For any other information or special requests (such as accommodating a learning disablility),
I am very grateful to be told about bugs and typos by email. An error message caused by your failure to follow directions is not a bug. I am unlikely to be able to determine the cause of apparent malfunctions unless you tell me
Before you conclude that unexpected results are caused by a bug,
Outside tutors: the Statistics Department has a list of people who have offered to tutor introductory statistics. The Department does not vouch for the proficiency of the tutors, and makes no recommendation, but keeps a list as a service to students. The Student Learning Center also offers extra help in introductory statistics classes.
Bulletin board. There is a class bulletin board (newsgroup) to which you can post questions, etc. The TAs and I will check the board regularly to answer your questions. This newsgroup is accessible only if you are connected to the web through UC Berkeley, for example, from the Statistics Department or another UCB department, from a UCB library, from a UCB public terminal room, using Home IP to dial in to a UCB modem, or using a dormitory ethernet connection. You cannot connect to it from AOL or other commercial ISPs.
Teaching Assistants will check the bulletin board periodically, answer general questions, and give hints and advice (but not answers) to homework problems.
You can attend the office hours of any of these TAs, regardless of the section you are enrolled in. Moreover, the Statistics Department TA office is staffed throughout the day, and TAs from other classes can help you with some problems if they are not too busy with students from their courses.
