Course Description: Stat 202 is an introduction to statistics that emphasizes working with data and statistical ideas. Topics covered include: classification of data, averages, variability, probability, frequency distributions, confidence intervals, tests of significance, least squares regression, and correlation. A computer package is used to demonstrate statistical techniques. A major focus for this course is the ideas behind, and the methods for, drawing conclusions about a population from a sample.
A Word of Warning: The Math/Stat Department at AU teaches STAT 202 to prepare students to use statistics in advanced courses required for many majors. Thus the STAT 202 instructor does not always have the luxury of setting the most comfortable and easy pace through the course material. The pace will be determined by what we need to cover for your future classes. There is a lot of material in the curriculum, so be prepared to work hard and spend a lot of time studying outside of class.
Another Word of Warning: The material gets progressively harder throughout the semester, and later topics build on earlier ones. Learn the foundations well, and don't fall behind, because it is hard to catch up.
To reiterate: Studying, and in-class, Expectations:
- Please note that this course is a 4-Credit Core Course and is part of the University’s Foundation Courses in Quantitative Literacy. We cover a large amount of material in this course (see the weekly schedule provided below). To do well in this course you will need to devote a minimum of 4 to 6 hours per week to studying the material over and above the time spent in-class. The study of Statistics is cumulative in nature – that is every single class builds on, and presumes, your mastering of statistical concepts & techniques covered in the previous class/es. In order to keep up with the class you will need to study & practice the weekly materials and maintain regular attendance throughout the semester.
Prerequisite: MATH-15x or higher, or permission of department. No prior knowledge of statistics is assumed.
Text for Class: Stats: Data & Models, Fourth Edition by Deveaux, Velleman, and Bock. Note the title of the text: there are two Statistics texts available with the same three authors, however the correct e-book comes free of charge with MyStatLab registration and registration for the course. A loose-leaf printed copy can be optionally purchased via MyStatLab for additional money. A bound copy can be optionally purchased separately, but this is expensive. Bound rental copies are available on-line for a very reasonable price.
Learning Management Software: MyStatLab from Pearson. Can be purchased from the bookstore and available as a free two week trial. Access instructions will be handed out on the first day of class. You must register for the section you belong to (001 or 002). You will need to upgrade your free access to full semester access. MyStatLab comes bundled with a subscription to the e-Textbook we will use for the course. You will need this bundle to complete and turn in the required homework.
Instructions for logging into MyStatLab for the first time:
- Section 001 (meets at 8:10 am): carver34822: https://portal.mypearson.com/course-home/handout/carver34822/Student_Registration_Handout_carver34822.pdf
- Section 002 (meets at 9:45 am): carver48006: https://portal.mypearson.com/course-home/handout/carver48006/Student_Registration_Handout_carver48006.pdf
Statistical Software: StatCrunch. StatCrunch is very easy to learn, and is a great pedagogical tool. StatCrunch (web-based software comes free with MyStatLab and is accessed through MyStatLab. You can also access StatCrunch from StatCrunch.Com but you may need to pay for access through this site.
Please Bring A Laptops To Class! I will be demonstrating software in class with the idea that you follow along with your own computer. Additionally, I will be giving problems to solve in class that require a computer. You may borrow a computer from the library if yours is temporarily unavailable.
Learning Outcomes: Learning objectives: At the end of this course you will be expected to
- understand the major concepts related to statistical reasoning and to statistical inferences for drawing such conclusions
- understand how these concepts are used in experiments and observational studies across many disciplines, and
- implement the methods yourself in statistical analyses.
Work will be a balance between understanding the concepts underlying a method, implementation of the method, and interpretation of the results.
This course is divided into four related areas of study:
- Data collection – the theory and practice of study design.
- Data summary and exploration – which illustrates to us how the data actually behave.
- Probability and sampling theory – from which we determine how we expect the data to behave.
- Data analysis – which allows us to reconcile our expectations with the actual data behavior so that we can make statistical inferences and drawing conclusions.
Office Hours: Students are strongly encouraged to come to office hours if they need or want help. My office hours are tentatively scheduled, as follows (days and times may be adjusted throughout the semester, please come talk to me if you want to come but can't make those times):
- Monday, Wednesday, Thursday: 11:40 AM - 1:00 PM
- No office hours during MLK day or Spring Break.
- My office is DMTI 208F.

- Please note that inconvenience with travel plans is NOT a valid excuse for not taking the final as scheduled.
- If you miss the final or any exam, you will need an excuse through the Dean of Students.
- With an excused absence, the make up may not be until next semester (June or September)...in the meantime you will get an incomplete.

|Midterm Exam 1||25%|
|Midterm Exam 2||25%|
- Calculators are allowed during homework and exams. Any simple calculator is absolutely sufficient.
- Collaboration on a homework or lab is OK, even encouraged! Exams are to be done individually.
Cell Phones and Other Media:
- Cell phones need to be silenced and put away during class. Personal use of electronic media during class time is highly distracting – it downgrades the quality of the classroom learning experience for everyone. Laptops (tablets, readers, etc.) should only be out during class time if they are being used for classroom activities. Please save texting, typing/sending emails, checking Facebook, etc. for outside of class time. If you need to attend to something urgently, it is OK to excuse yourself from the classroom.
Accommodations: Please let me know during the first week of classes if you have any special needs that require accommodations.
Incompletes: A grade of incomplete will only be given under extreme circumstances and will not be granted to any student who is failing.
Homework: Assigned, completed, and automatically graded through MyStatLab. MyStatLab has on-line help to assist with problems. An incorrect problem can be attempted again.
Quizzes: On the first day of every week (except the first week) there will be a quiz to test your knowledge of the material. These quizzes will not be for credit and will be self-graded. Bring a pen or pencil and something to write on.
Exams: You will use a lab computer if one is available. Otherwise, you will need your computer. You can borrow a computer from the library, if needed. You will have access to StatCrunch. You will not be able to do Google searches, access this website, or use your computer in any other way, unless cleared by instructor. Absences on exam days must be excused through the Dean of Students, who needs to send a letter to me indicating that they excuse your absence. If excused through the Dean of Students, you do not need to disclose the reason to me.
Participation: Periodically, I will assign labs to be completed in class. For these labs you will receive a participation grade.
Attendance: Roll will be called all or most days of class so please see me at the end of class if you came in late. You are expected to attend every class. However, there can be compelling reasons why you may need to miss class, once in a while. You must email me if you are not going to attend within 24 hours after the class you missed. Please indicate the reason, unless your absence is being excused by the Dean of Students---in which case, let me know this. Absences are OK only occasionally and only for good reasons (such as sick, religious holidays for faith you practice, varsity meets for a team you are on, etc---not a complete list). If you need to miss more than occasionally, even if it's for good a good reason, please consider dropping the class. If you miss one or more times unexcused, or more than occasionally excused (not counting those excused through official channels) you may receive an "early warning." After your warning you are in danger of losing all credit (all 5%) in the attendance category. Every day builds upon the material previously covered, and missing class puts you at a disadvantage, even if it is for a good reason.
Class time: Class time will be divided between lectures, quizzes, and labs. In addition, there will be plenty of class time devoted to working on homework with my supervision (active learning). You are permitted to access the book at any time during class, except during the no-credit quizzes and for-credit exams. Think of the no-credit quizzes as a dry run for the exams, so they will operate under the same rules.
Class Etiquette: Please participate in class by asking questions when you do not understand something. Invariably other students benefit from these questions. Please engage in discussions, and please engage with the class, generally. I find it easier to give good lectures when students are asking questions, and engaging with the material.
Academic Integrity: Cheating is not acceptable and will not be tolerated. Consider this: in subtle ways, cheating to get a better grade on an exam can result in lowering the grades of some of your classmates. Certainly this is true when a specific curve is used to assign grades. Even when I don't use curves explicitly, they can be implicit in decisions about writing and grading exams. I will handle all cases of suspected cheating according to the policies of American University. Specifically, I am required to report cases of academic dishonesty to the Dean of the College of Arts and Sciences. Cheating is giving or receiving unauthorized assistance on exams, from other students or other people, from notes, from books, or from the web. AU’s academic code is found at http://www.american.edu/academics/integrity/
