Statistics 371: Introductory Applied Statistics for the Life SciencesProfessor: Bret LargetOffice: 1250A MSC (Medical Sciences Center)Contact: Phone: 262-7979; E-Mail: [email protected]; (email preferred)Web: http://www.stat.wisc.edu/∼larget/Office Hours: Mon. 11:00–noon, Tue. 3:45–5:00, Wed. 8:00–9:30, and by app ointment.Class Hours: T R 8:00 – 9:15Room: 331 SMI (Service Memorial Institute)Textbook: Statistics for the Life Sciences, Third Edition, by Samuels and WitmerPrerequisites:While there is a formal prerequisite of background mathematical knowledge that could be satisfied by acourse in college algebra or calculus, the course requires no calculus and minimal algebra. Credit cannotbe given for this course if you have already completed Statistics 201, 224, 301, or 324.Students will need a scientific calculator with statistical functions. Any scientific calculator that cancompute a standard deviation will suffice.Course Objectives:The primary course objec tives are for the students enrolled in the course: (1) to develop mastery of basicstatistical concepts; (2) to develop the ability to apply these concepts correctly, especially in problemsoriginating in the life sciences; (3) to learn to communicate effectively in writing the results of a statis-tical analysis to a non-statistical audience; and (4) to gain basic competence with the modern statisticalcomputing software R.Statistical Computing:Modern statistical practice depends on statistical computing. For many homework assignments and someexams, I will ask you to use R, an open-source free software that runs under Windows, Macs, and Linux.R is also available in several public computer labs on campus. If you learn to use R well in this course, youwill have gained a skill will benefit you in your other courses and whenever you need to do data analysisthe res t of your life.Some exams will include a take-home portion in which I w ill expect you to carry out some analyses usingR. In-c lass portions of exams will not test R syntax, but will ask you to interpret R output.Grading:Your grade will be determined by exams (90%) and homework (10%). There will be nine short examsthroughout the semester, each worth twenty points. On some days I will give two short exams. Duringthe final exam period time, you may take additional exams to replace worse scores from earlier exams orscores from exams you missed.I will convert your homework total to a score from 0 to 20 with 95% or higher earning 20 points, 90% orhigher earning 19 points, and so on.I w ill assign course grades according to this scale:Course Points Grade188–200 A174–187.5 AB160–173.5 B146–159.5 BC120–145.5 C110–119.5 D0–109.5 FIt is possible for a student who does well on all of the exams and on the homework to earn an A prior tothe final exam period.Exams:The nine exams will be in three categories — probability (3), one- and two-sample inference (3), and linearmodels (3). Each exam is worth twenty points. I will not give make-up exams during the semester— if you miss an exam, you will need to take a replacement exam during the final examtime. Specifically, I will not give make-up exams for attending family functions, extending breaks, orillness. There is no penalty for missing an exam other than a need to make it up during the final examperiod. At my sole discretion, I m ay permit alternative exam times for students who give me prior noticeof a university-related conflict.Homework:There will be 12 homework assignments worth 50 points each consisting of exe rcise s from the textbook,exercises from other s ources, and problems to solve by computer.Your homework solutions should be organized and neat with solutions in order the order problems wereassigned. Each problem solution should include a brief description of the problem (that may be paraphrasedfrom the actual problem) as well as your work. We will penalize homework that is not clearly legible andout of order. Very late homework will receive no credit.Honors:Student taking the course for honors will write a short criticism of the statistical methods employed in twopapers and will carry out and report on statistical analyses based on data from these papers.Course Web Page:The course web page will include an anticipated schedule including exam dates, homework assignments,supplementary notes, help for the s tatistical package, and other information useful for the course. You willbe able to access the course web page from my home page, http://www.stat.wisc.edu/~larget/.Academic Honesty:You are permitted and, in fact, encouraged to talk to other students, your teaching assistant, or me abouthomework. Your TA or I may give you clues or discuss similar problems without doing your homeworkfor you. You may look through books or Web pages for solutions to problems. However, you may notpresent other people’s work as your own. Make sure to include with any submitted solutions to problemsreferences to any sources of direct assistance. If you work with other students solving problems, make s urethat you write up your own solution independently. It is not acceptable for one student to write a solutionfor another student to copy.You must work independently during exams, including take-home portions of exams. You may not sharecalculators or pass notes during the
