Great Math Student, by Richard Smith
The goal of this course is to learn to use and interpret statistics, for the purpose of making valid conclusions from sets of real data. This course does not fulfill the distribution requirement in mathematics/computer science. It is not intended for mathematics majors.
Your grade will be based on three tests (worth 100 points each), a final exam (worth roughly 200 points), and as many as five projects (worth a total of up to 130 points). Many, if not all, of these projects will be done on a computer using the SPSS statistical package. You do not need previous computer experience. If you miss a test, it will ordinarily count as a zero without a valid excuse. If illness or other exceptional circumstances prevent you from taking a test, please contact me as soon as possible to discuss what to do. Grades of Incomplete will not be given except for extraordinary circumstances.
Below is the minimum daily homework assignment; you should do as many additional problems as you have time for. The more you do, the more you learn. Turn in the homework two class days after it is assigned. To be counted, the homework must be done correctly and turned in on time with all the work showing. Late homework will not be accepted unless illness prevents you from attending class. Each of you will grade homework for one day. Your homework grade will be averaged with your lowest test grade, assuming that improves your grade. I will not collect the review problems.
Since you are responsible for everything said in class, be sure to get the notes from someone else if you are absent. The details of this syllabus may change as the semester progresses; stay tuned for the latest update. I am roughly covering Syllabus Version A on p. xxviii in the text, except I have added sections 2-4, 2-5, and 6-4. This is basically the same as Syllabus Version B on p. xxix, but with section 2-5 added and sections 4-3, 4-4, 8-6, and 11-3 removed.
This course has a prerequisite of intermediate algebra with ability to use logarithms and exponents.
You will need a calculator with statistical features for this class. I strongly recommend the TI-83 Plus or TI-84 Plus.
All students are expected to abide by the University's Policy on Academic Honesty (p. 52 of the Hofstra University General Bulletin 2009-2010).
