Other times, gladly, by appointment. Arrange appointments after class, send e-mail, or leave voice mail. Course Information Course Description: This course is designed to enable you to use statistics for data analysis and to understand the use of statistics in the media. The course makes use of SPSS, a widely-used statistics package for the computer. Course topics include graphical and tabular presentation of data, measures of central tendency, dispersion, and shape, linear transformations of data, correlation, regression, probability, the normal probability model, sampling, t-tests, and one-way analysis of variance. The course meets MWF from 9:45-10:40 in HS4. On days when we have an exam, the course will meet from 9:45 10:50. Recitations: Recitations for this class meet on Thursdays from 9:25 10:15, from 10:25 11:15, and from 11:50-12:40 in BC 21. You may attend any recitation, according to what is convenient for you, in a given week. The primary purpose of recitation is to go over homework and any questions that you may have about the textbook, lectures, or exams. I recommend that you bring any written-up solutions that you create where your answer is different from the solutions provided in the back of the book to recitation to have me evaluate them. There is a focus on statistical writing in this course and it is good practice to get your writing evaluated before the tests. We also discuss statistical articles and there are times when I give you additional exercises to complete. You have the option of taking old quizzes for practice. Recitation is also a good place to meet a study buddy. The SPSS software and your laptop computer are required for recitations. When you attend recitation with the computer you are going to use for the tests and practice the relevant statistical applications, you are much less likely to have computer problems during the tests. E-mail: Please check your e-mail daily for messages from me. Associated Materials Text: Weinberg, S., and Abramowitz, S. (2008). Statistics Using SPSS (2nd ed.). New York: Cambridge University Press. It is available through the bookstore. Statistical Software: SPSS 16 for Windows. The software package is available for free through the Drew network when you are on campus. You have the option of purchasing the student version of this computer package at the bookstore (student version of SPSS 15). I recommend that you purchase the software if you plan to use it at home a lot (for example, you are a commuter student). Otherwise, you should use the network version, which is free. Laptop computer: Unless otherwise notified, you must bring your laptop with the SPSS software installed on Thursdays, when we have recitation, and on Fridays, when we have quizzes and exams. You will need a fully charged battery or your power cord and your network cable. HS4 does not have reliable wireless service, but it does have a power outlet and network jack at every seat. If you take your computer to be repaired at the Helpdesk, review the loaner policy and then fill out a request by visiting http://depts.drew.edu/cns/support/forms/loaner.php. You will fill out an online form and send me e-mail to verify your need for a loaner. I can send an e-mail to CNS and get your request for a loaner expedited. If you are unable to bring a laptop to class, as long as you notify me at least 15 minutes before class starts, I usually can bring you a loaner. Please give me as much advanced notice as possible. If you do not request the loaner before class, but instead let me know in class on the day of the exam or quiz that you do not have a computer, you will receive a 0 on the quiz or exam. Moodle: We use an online course management program: Moodle. You will receive further instructions for Moodle during the first recitation. Using Moodle, you will be able to check your grades and access course assignments and documents. The URL is  HYPERLINK "http://moodle.drew.edu" http://moodle.drew.edu Grading Homework: Doing homework is essential for learning statistics. There are concepts and topics that are not discussed in lecture but are treated in the homework and are tested. Homework assignments are discussed in lecture. Usually, completion of the homework is necessary for understanding the lecture on the next topic, so it is critical to keep current. These assignments are important, but they are not collected and graded because complete solutions are available in the back of your textbook. Most of these assignments include questions that should be answered using SPSS. It is your responsibility to complete homework assignments on time and to raise related questions in lecture. Collaborating with other students on the homework is allowed. I expect that you will spend at least 6 hours per week doing homework and studying for this class. If you are spending significantly more or less time than that, please let me know. A list of assigned homework exercises is given at the end of this syllabus. Classwork: At times during the semester there are assignments given in class, which may be worked on collaboratively. They are collected that day and cannot be made up. Tests: There are weekly in-class quizzes on Friday on the homework material for the week. Your lowest two quiz grades are dropped. There are three exams, and one cumulative final exam. Your performance on the final exam may be used to raise your three exam grades. Dates for exams are indicated on the tentative outline attached. You are permitted to bring one 8.5 by 11 inch formula sheet of your design to every exam. You may bring four 8.5 by 11 inch formula sheets to the final exam. You may not use formula sheets for the quizzes. Most test questions require the use of SPSS. Unless otherwise informed, you must bring your laptop with the SPSS software installed (and your network and power cables) to every quiz and exam. The final exam is scheduled by the registrar during finals week. If you need to take the final exam at a different time, you must make arrangements through Dean Lawlers office. Project: In order for you to apply the statistics you are learning to a topic that interests you, there is a short project assignment. You will choose a question to address based on a data set that you choose. You will answer the question and support your answer with relevant statistics. Make-ups: There are no make-ups allowed for any in-class assignments, exams, or quizzes after they are administered. All unexcused absences on assignments and tests will results in a grade of 0. If you have a Deans excuse for your absence, the 0 will not count. If you know in advance that you will not be able to take a quiz or exam, you may arrange with me to take it early. Extra credit: None. Grade composition: Quizzes and class work: 15% total Project: 15% Exams: 15% each = 45% total Final Exam: 25% If your average is below 60, you will get a U in the course. Miscellaneous Tutoring: There are weekly group tutoring sessions led by former Math 3 students from 9-11 pm on Thursday nights, location TBA. You do not need an appointment and may attend as needed, but know that its difficult to get attention the night before an exam. In addition, individual peer tutors, students that did exceptionally well when they took Math 3, are available at no charge through the university for one-on-one tutoring. Individual tutors can be helpful for students who are anxious or those who are attending, doing the course reading and assignments, and are still experiencing difficulty. Tutors are not a good substitute for hard work on your part. It has been my consistent experience that students who are not working hard themselves or not attending class benefit very little from tutors. To arrange for an individual tutor, go to  HYPERLINK "http://www.drew.edu/depts/StudentAffairs.aspx?id=8017" http://www.drew.edu/depts/StudentAffairs.aspx?id=8017 and fill out the application and then schedule an appointment with Professor Allison Leddy ( HYPERLINK "mailto:aleddy@drew.edu" aleddy@drew.edu, X3962). It takes time to get a tutor, so dont wait until the last minute. Academic Accommodations (such as extended time on tests): Requests for academic accommodations must be formally filed with the Office of Educational Services and it is your responsibility to self-identify with that office if you qualify. To schedule an appointment, call x3327 or stop by BC 114. If you qualify for these types of accommodations, you must provide me with the appropriate written documentation and inform me at least one week in advance of every exam and quiz and schedule a mutually convenient time for you to take the test. There are no retroactive accommodations. Academic Honesty: No collaboration is permitted on tests. Cases of suspected cheating are taken seriously and referred to Dean Levin. You may discuss the homework assignments with other students. However, keep in mind that it is always easier to understand a problem when you are working through it step by step with another person than it is when you are on your own. When you write up the solutions yourself or do some of the exercises on your own, you are better able to assess how much understanding you have. Study Advice: Consistent practice is vital. Study for two hours at a time, three days a week. This approach is preferable to cramming because you have a better chance of retaining your knowledge. The final is cumulative and this course is a pre-requisite for many others, so learn for the future, not just for tomorrows test. Furthermore, you better understand a new topic when you have a solid understanding of the material that came before. Be an active learner. Pay attention in lecture and ask questions as they arise. Answer questions posed in lecture by the professor. Pay attention as you do homework and note any questions that arise. Ask those in the next lecture. Study with at least one other student at least once every week. Verbal interchange and interpretation of concepts and skills with other students helps you verify and retain your knowledge. Don't try to memorize formulas or SPSS commands. Study concepts. As long as you know what statistic applies to a given situation, you can look up the related details in a textbook or through the SPSS help menu. Make sure your study sheet for the exams is consistent with this emphasis. It is a good idea to include examples, so work on your study sheet as you do the homework. Get the most out of lecture. Statistical knowledge is cumulative, so try not to miss class. If you do, read the text that corresponds to the lecture you missed before coming to class. If youre having trouble following in lecture even though your attendance is good, read ahead. The pages in the text that correspond to the lectures are given in the syllabus. Work as many and varied problems and exercises as you possibly can. You can not learn statistics by just reading about it or watching someone else do it. Another benefit of hands-on practice is that you work out all of the kinks with SPSS and your laptop before the exam. Look for reoccurring themes in statistics. There are only a handful of important skills that keep appearing over and over again. If you are a victim of math or statistics anxiety do something about it! We understand the debilitating nature of this problem and provide excellent counseling and tutoring programs to help you. Do get help early in the semester, either by signing up for tutoring, attending a workshop, or speaking with me. Take the Learning Styles Inventory.
