I’ll be teaching one section of Statistics during Spring Semester 2013. To determine whether you are in fact enrolled in George Barrick’s section of this course, compare the course information in your schedule to see whether your section number of MATH 221 has the call number (20463). Section (20463) meets at 12:40 MWF in TNSC 011.

Text

The text for Statistics (MATH 221) is the seventh edition of Elementary Statistics: a Step by Step Approach by A.G. Bluman (ISBN 97800-7353497-8). It’s available from from the Walsh Bookstore ($198.95 new/$149.20 used/$136.20 e-book/$106.45 e-book rental). Another good source for these books is Barnes & Noble. When using e-commerce sites, you’ll need to wait a couple days for shipping. Keep in mind that Walsh Bookstore will buy back relatively undamaged books (though not e-books) in May at approximately 15% of the original retail price, and so it’s not a bad idea to keep your books in good condition.

Calculators

A scientific calculator is recommended for the course. The recommended calculators are the TI-30X IIS, TI-34 II, TI-36X, TI-83 Plus, TI-84 Plus, TI-89 and TI-89 Titanium. These vary in price from $13.98 up to $171.98. The recommended calculators may be used on tests and on the Final Examination. Calculators, cell phones, PDA’s or laptop computers that might either store text notes or host wireless network links may not be used during quizzes or tests.


Software

The common spreadsheet program Excel from Microsoft can be useful for statistical computations. The software package Mathematica is a useful piece of software for students in academic settings, but only Ms. Excel is required. Students will also need to use either Ms. Wordpad or Ms. Office Word with the Equation Editor 3.0 in order to type up homework submissions that include some mathematical formulas.


Quizzes

One component of the grade in the class is quiz scores. Quizzes will take place frequently as part of the class period. It’s a good idea to keep up on the class schedule and class assignments, so as to be prepared whenever quizzes occur. Something on the order of 12 quizzes at 10 points each will be recorded during the course of the semester, though only the highest 10 of these grades will be used for each student’s quiz score. When you are absent from class, you’ll need to notify the instructor on the day of the quiz in order to make up quizzes that you miss. All students must make up missed quizzes within two weeks of the day the quiz was presented.

Homework

Daily homework from the assignment sheet will not be turned in for class credit, though it is these examples that will be covered every day in class. Five short homework assignments that require more careful write-ups will be turned in for 20 points each. These assignments may involve some graphing and numerical computations, and students are required to submit these in a timely fashion in the form of typed hardcopy. Homework assignments should be turned in on the day the instructor asks for them in class. Homework that is turned in late will be subject to penalties. Homework turned in more than four weeks after the due date will receive no credit.

Project

The hypothesis-testing project will be assigned during the last month of classes. This assignment requires a carefully presented write-up that is worth 50 points. You will need to work through the sampling and statistical preparation of a moderately-sized data set, derive conclusions, and compare them to the statistics describing the larger frame (population) of experimental units. The project, in the form of typed hardcopy, must be turned in on April 19. Projects that are turned in late will be subject to penalties. Projects turned in after the date of the final examination will receive no credit.

Final Examination

The final examination meets on Wednesday April 24, 2013 from 3:00 p.m. to 5:00 p.m. in TNSC 011. All of the information presented here, as well as more detailed things regarding grading policies etc. can be found in the class syllabus, the class schedule and class assignments.

MATH 221 Quiz Archive

All of the quizzes will be posted here within a few days after they’ve occurred in class. All students are encouraged to look through these old quizzes as a study guide.
