Course computing: SPSS - available on all campus computers. (You may need to install using the Software Center ask myself or someone in IT for help if needed).
This course is an introduction to the principles of statistical thinking in the spirit of the liberal arts. Students will learn the language, practical applications, and concepts involved in statistical reasoning. Statistics is the science of learning from data. By now you are aware that vast amounts of data are collected every moment in a variety of settings like political polls, clinical trials, stock markets, and social media user metrics to name just a few. Statistical methods are necessary to extract information, create predictions, and make evidence based decisions using data.
This is not a course in mathematics. Although we use mathematics, statistics is quite different. Be prepared to think and read critically in this class. In addition, there is a language and vocabulary of statistics that is important to use properly.
To explore how statistics assists in understanding and reasoning with the vast amounts of data produced by society.
To become a critical consumer of statistical data, scientific reports, and their conclusions.
To make decisions under uncertainty.
To design a data collection protocol, collect data, analyze the data to answer research questions, and summarize the conclusions using visualizations, summary statistics, and clear exposition.
To learn how to perform the above using the software program SPSS.
This course and this textbook are centered on the idea that you will better understand and retain important statistical concepts if you build your own knowledge and practice using it, rather than by memorizing and regurgitating a set of facts. In order to actively construct knowledge in statistics, you must:
Engage in the material and think carefully about it; there are rarely rote, black and white solutions in statistics.
Attend class, participate in class, and complete pre-class preparations.
Attend labs, develop skills using SPSS, and transfer those skills to data beyond homework and test situations.
Expect weekly homework sets, occasional table quizzes, and longer projects which allow you to pull your knowledge together.
Your course grade will be determined as follows:
| Category | Weight |
|---|---|
| Homework Assignments | 10% |
| Lab Assignments and Participation | 10% |
| Quizzes | 10% |
| Midterm Exams (2) | 20% each |
| Group Project | 10% |
| Final Exam | 20% |
College wide grading benchmarks can be found at: http://catalog.stolaf.edu/academic-regulations-procedures/grades/
Weekly homework assignments will be assigned and submitted through Moodle as a PDF document. Homework assignments are designed to give you practice applying new statistical concepts to new data contexts. Homework will be drawn from the exercises at the end of each chapter as well as additional questions.
You are encouraged to discuss problems together, but each person must hand in their own work.
If you work with other students, you must note this fact (along with the students’ names) on your assignment.
You must show your work for full credit.
Homework is due by 11:59 PM on the due date (generally Tuesday). Late homework assignments will not be accepted. This includes late assignments due to technical issues. Plan ahead. The lowest homework score will be dropped.
I expect that you will start soon after receiving the assignment. The assignments are definitely not designed to be one-night jobs.
Short reading reflections (less than one page) will occasionally be due, especially at the beginning of the semester. These will be graded on your ability to thoughtfully and concisely respond to a specific reading. Please keep to the length restrictions.
You will submit a write-up for each Friday lab. Most work will be completed during lab, but you may need to finish on your own. Lab assignments are due the Monday following lab at 11:59 PM to give you time to write a careful response. You are encouraged to work with others, but must submit your own work. Late lab assignments will not be accepted, but the lowest lab score will be dropped. Lab attendance is factored into your final grade.
You will take 8-12 in-class quizzes throughout the semester. The purpose of these quizzes is two-fold. First they provide immediate reinforcement and enhancement of important points from the reading and previous classes. Second, they provide me with a better idea of what materials you understand thoroughly, what material is proving difficult, and what material to cover in more depth during class. The format of these quizzes will vary - individual or group, self-selected or randomly-assigned groups, open book or closed book, etc. Quizzes will never be focused on new material. If you miss class, you cannot make up a quiz, but your lowest quiz score will be dropped.
The midterm and final exams will focus on your abilities to interpret results, to express an understanding of statistical concepts, and to engage in statistical thinking on open-ended questions. They will not focus on plug-and-chug mathematics or hairy mathematical proofs. Make-up exams will be granted only under very special circumstances, and only if arranged in advance.
A group project will be completed by the end of the semester. These are team-oriented tasks that will require hypothesis generation, data analysis, critical thinking, and thoughtful presentation of statistical results. Additional information on the project, including due dates will be provided later on in the semester.
Computers will be used during the Friday labs. Computers mean we do not need to perform tedious calculations but will allow us to learn how statistical methods work in practice. Computing is a necessary part of the course, but certainly not the emphasis. Students who use computers during lab time for purposes beyond Stat 110 (email, internet surfing, paper writing, etc.) may have their computer privileges revoked.
You are expected to come to class having read the assigned readings and completed assigned work. You will be asked to show work on the board, work with classmates on in-class activities, and engage in classroom assignments. Course grades may be adjusted based on class participation and attendance.
I am happy to take any questions in class, no matter how trivial they may seem. To facilitate an open learning environment, please respect each other. Raise your hand, listen when others are talking (including me), and avoid distracting or rude behavior. Please turn off your cell phone ringers, and refrain from using your phone during class. Lecture slides or notes will be posted on Moodle. I reserve the right to restrict laptop use if I believe the privilage is being abused.
You can all be successful in this class! If you are struggling or if you’re feeling good about things but have some questions, there are several resources:
Come see me at my drop-in office hours, or make an appointment, or see if my door’s open
Connect with your classmates.
CIR Office Hours are Mon 1-2 pm; 7:30-8:30, Tues 2-3pm; 8-9pm, Wednesday 7:30-8:30pm, Thursday 3-4pm; 7:30-8:30pm, and Sunday 7:30-8:30pm.
Visit the Academic Support Center if you want to improve your general study skills and habits.
Tutors are available through the CAAS. I will only approve a tutor request once you have taken full advantage of resources available to you in and out of class. You are encouraged to work with classmates on homework and form study groups. You are required to attend SI sessions and office hours prior to requesting a tutor. Additionally, you must discuss with me your goals for working with a tutor prior to placing a request with ASC. Absence from class will prevent you from obtaining or continuing with an assigned tutor.
I am committed to supporting the learning of all students in my class. If you have already registered with Disability and Access (DAC) and have your letter of accommodations, please meet with me as soon as possible to discuss, plan, and implement your accommodations in the course. If you have or think you have a disability (learning, sensory, physical, chronic health, mental health or attention), please contact Disability and Access staff at 507-786-3288 or by visiting wp.stolaf.edu/academic-support/dac.
In keeping with St. Olaf College’s mission statement, this class strives to be an inclusive learning community, respecting those of differing backgrounds and beliefs. As a community, we aim to be respectful to all citizens in this class, regardless of race, ethnicity, religion, gender or sexual orientation.
I am committed to making course content accessible to all students. If English is not your first language and this causes you concern about the course, please speak with me.
Plagiarism, the unacknowledged appropriation of another person’s words or ideas, is a serious academic offense. It is imperative that you hand in work that is your own, and that cites or gives credit to others whenever you draw from their work. Please see St. Olaf’s statements on academic integrity and plagiarism at: https://wp.stolaf.edu/thebook/academic/integrity/. See also the description of St. Olaf’s honor system at: https://wp.stolaf.edu/honorcouncil/
St. Olaf’s Academic Integrity Policy, including the Honor System, is an integral part of your academic experience. I consider any violation of this code to be extremely serious and will handle each case appropriately. Here are some guidelines for this class. They do not cover all eventualities so if you have any doubts about a course of action you can ask me.
Homework assignments may be done in collaboration with other students (this is highly encouraged). However, the final product must written by you, in your own words, unless group assignments have been specifically allowed.
In no event can you copy answers from another student, a website, solutions manuals, or elsewhere.
When you sign your pledge on an exam that you have “neither given nor received assistance, and seen no dishonest work” I treat your signature as your solemn pledge that all your actions have been honorable. For example, if we have a take-home exam, you are assuring me that you shared no information with others, that you did not solicit or receive help from anyone besides me, etc.
Don’t treat the honor code lightly; if you’re in doubt about a possible violation, ask me.
