In this course, you will have the opportunity to:
- Describe why statistics is central to scientific inquiry (& your field of interest);
- Define basic statistical words and symbols;
- Design simple experiments and sampling strategies;
- Perform appropriate exploratory data analyses (univariate and bivariate);
- Identify the purposes of and conduct and interpret the results of a linear regression;
- Construct and interpret confidence intervals for one and two-sample mean and proportion problems;
- Identify the appropriate hypothesis test to perform in one- and two-sample quantitative and categorical data situations;
- Construct and interpret the results from a hypothesis test for one- and two-sample quantitative and categorical data situations; and
- Communicate statistical results and ideas in a succinct and informative manner.
This course fulfills that Quantitative Reasoning requirement in the General Education Program because you will:
- Communicate mathematical information symbolically, visually, numerically, and verbally;
- Use statistical or mathematical models in solving problems; and
- Think critically about the validity of conclusions that are based on statistical or mathematical models.
Don’t be afraid to ask questions. Don’t be afraid to ask for help when you need it. I do that every day. Asking for help isn’t a sign of weakness, its a sign of strength. It shows you have the courage to admit when you don’t know something, and to learn something new. – President Barack Obama
Instructor – Derek Ogle
I will answer to “Derek”, “Doctor Ogle”, “Professor Ogle”, or “Doctor Professor Ogle, Sir” … whichever you prefer. 😀
I am committed to your doing well in this course and see it as my responsibility to help you both in and out of the designated class period. There are several good ways to get help from me.
- Attend class. Most of class time will be allocated to you working on module assignments. I will be available during these times to answer your questions.
- Ask questions on MS Teams. Simply start a new conversation (see quick links on course homepage) with your question and I will answer it ASAP. Other students may also answer your question.
- I will hold virtual help hours on Teams Monday through Thursday from 830-930 PM. You can simply join the meeting that I open in the Help Hours channel (see quick links on course homepage) at that time.
- I will also generally be available at my computer during afternoons on most days. I will try to respond to queries ASAP during these times.
- Finally, you may send me anonymous feedback, suggestions, or questions.
Please see or contact me if you have questions regarding this course.
Northland College offers free tutoring to aid you in your academic success. Seek a tutor early in the semester so that you can establish a regular meeting schedule, develop your skills, and receive the cumulative and beneficial effects that result from ongoing sessions. Drop-in tutoring for statistics is available on Mon, Tues, Wed, and Sun from 7-8pm in the tutoring center in the basement of the Dexter Library. If you have questions about tutoring or would like one-on-one tutoring please contact Academic Affairs.
I want to create an inclusive and accessible learning environment for those of you that have a condition (e.g., attention, learning, vision, hearing, mental, physical, or other health-related concern) that may require special accommodations. If you have already established accommodations with the Office of Accessibility Resources (OAR), please communicate your approved accommodations to me as soon as possible so that we can discuss your needs in this course. If you have a condition that requires accommodations but you have not yet established services through OAR, then you should contact the Accommodations Specialist as soon as possible (firstname.lastname@example.org). It is the policy and practice of Northland College to create inclusive and accessible learning environments consistent with federal and state law. More information is available here.
If I observe you “struggling” with the course early in the semester then I may issue an “Academic Alert” about you. If this happens, you will receive an e-mail from me that will suggest steps you can take to improve your performance in the course. Our Academic Success Coordinator will also receive the alert and will likely also reach out to you. Academic Alerts are not punitive, they are simply an attempt to help you get back on track in this course as soon as possible.
This course is taught in a “flipped format”, which loosely means that you will be responsible for obtaining factual content prior to coming to class and will then use class time with me to apply and expand upon what you learned prior to class. I have taught this class in this format for seven years, largely because I believe the science that indicates that deeper learning is achieved with this model. However, this format also allows for providing more direct assistance as needed.
The course is composed of daily modules (see link in upper-right) of material. The following is a general workflow that will be followed for each module.
- Prepare Module Material – A detailed reading, pertinent videos, and “introductory” videos from a previous semester are provided for each module. You will need to engage thoroughly with these materials. By this, I mean that you need to be focused (i.e., not distracted) while reading and you need to think hard about concepts that don’t make sense to you after your first read. A cursory reading likely will not be adequate. Here are some quick tips for how to read a math textbook.1
A “Preparation Guide” is provided for each module’s prepartory material. You should prepare (neatly) hand-written,2 answers to the guide questions. Please ask questions you have about the preparatory materials on the “Questions - Preparation Guide” Teams channel or during help hours (quick links on class homepage). Your “Preparation Guide” answers will be turned in via GradeScope (quick link on class homepage) by 11:59 pm (1 minute before midnight) on the day before the module is covered in class (see Dates page). The “assignment” on Gradescope will have the module name and “– prep” suffix. I will grade your answers according to the following rubric.
|5 points||4-1 points||0 points|
|All questions were answered thoughtfully and fully. Document was hand-written. Answers not nearly identical to someone else's answers.||Various numbers of questions were not answered, were answered incorrectly, or without care or depth of thought. Answers not nearly identical to someone else's answers.||Very few answers were provided or were correct; answers were nearly identical to someone else's answers; answers were not turned in; or answers were not hand-written.|
- Class Time – The initial part of class time will consist of a very short introduction to the module assignment and a quick discussion of any questions that you had from the preparation materials. Following this you will work on the module’s application assignment. I expect you to attend class to get direct help from me and learn from other students’ questions. If you are diligent and focused, you will likely finish most of the module assignment during this time.
- Complete an Applied Assignment – Module assignments should be prepared as described in the “Getting Organized” module for handing in on GradeScope (quick link on class homepage). The assignment on Gradescope will have the module name and “– assignment” suffix and is due by 6 pm on the day after the class period dedicated to the module (or by 6 pm on Sunday for Friday’s modules).
I will grade 50-100% of each module assignment “for content” (i.e., whether the work is done correctly or not). Questions that I did not grade “for content” will be graded “for completeness” (i.e., whether the work was done completely or not). You will receive a short e-mail from me when your graded assignment is available on GradeScope. You are expected to review your grade and comments (how-to video here) to better learn the material and to improve on future assignments. Detailed answer keys will be made available on the module webpage.
An overall grade will be computed from the module preparation guide answers and assignments described in the “Course Workflow” section, a capstone assignment, and your attendance to class according to the percentages below.
My philosophies for the grading percentages are as follow:
- Attendance: Attending class is important as this is a time to get your questions answered and hear explanations of important concepts and class announcements. The percentage is fairly low however so that missing a class is not too onerous a penalty.
- Preparation Guides: Success in this course is predicated on your preparing for material prior to class and then applying what you learned, or asking questions, during class. This percentage and the grading process described previously acknowledges your effort for this work.
- Module Assignments: Statistics is best learned with practice. In this class practice is your work on module assignments. The percentage for this assessment is intermediate to “give you credit” for this work and to motivate you do do well on the assignments, but to not incur a deep penalty if your work is not perfectly correct as these are the first chances you will have to apply your developing skills and knowledge.
- Capstone Assignment: This assignment will focus on larger concepts, applications, and interpretations (rather than specific details) from throughout the semester. I will provide you with an explicit study guide approximately one week before the assignment is due. It is worth a higher percentage as this will assess your overall development of skills and concepts from the course.
Your letter grade will be assigned from your overall percentage (rounded to a whole number) and the table below.
|A 92-100||A- 90-91|
|B+ 87-89||B 82-86||B- 80-81|
|C+ 77-79||C 70-76|
|D+ 67-69||D 60-66||F 0-59|
Attendance will be graded on a 0-1 basis. If you attend the entire class period then you will earn full credit. However, if you do not attend class, if you come substantially late, or leave substantially early then you will receive no credit. If you finish the module assignment during class then please begin to prepare the next module. If you finish that preparation then show me what you have done and you can discretely leave class early.
Absences for school sponsored events (e.g., special sessions of other courses, athletics) will be excused. Other planned absences (e.g., family events, doctor’s appointments) cleared with me in advanced will be excused. Please see the COVID-19 section below with respect to missing class due to illness. Excused absences will not negatively impact your attendance grade.
Module preparation guide answers and assignments not submitted by the due date time will not be accepted (but please contact me to let me know your circumstances for not being able to complete the work on time). However, you can request (via e-mail to me) a 24-h extension for up to two Preparation Guides and two Module Assignments.
Monitoring Your Grade
Grades on individual module preparation guides and assignments can be found on the class Gradescope page (quick link on class homepage). I will update your percentage grades for the Preparation Guides, Module Assignments, and Attendance on mycourses.northland.edu (quick link on class homepage) at the end of each week, which will then show your grade as of that time. You can also compute your overall grade at any time by entering your percentage scores in the table above for completed assessments. To project your future grade, also include percentages for future assessments.
An incomplete grade will be given ONLY in extreme circumstances that are beyond your control, such as a major illness, and will ONLY be given if you have successfully completed the entire course except for the final exam. This is in accordance with Northland College policy (scroll down to “Incomplete Grades”).
I will submit a “midterm grade” for you approximately half-way through the semester. This grade will by my best guess at your lowest possible final grade. I assign this “worst-case” midterm grade because I believe that it is better to know the worst rather than the best-case scenario at that point of the semester and the material at the end of the semester is a little more difficult than the material at the beginning of the semester. Of course, see me if you have questions about your midterm grade.
Classroom Conduct and Academic Integrity
My intent is to create a classroom environment where learning can occur. One part of this environment is a well-organized course structure built upon relevant learning resources and interesting realistic exercises. Another part is my availability to assist you in learning from these resources and exercises. A third part is your conduct within the classroom. My expectations of you are that you will fully engage in the course (see above) and be respectful of all others in the class. At a minimum, I expect you to adhere to the following behaviors:
- Please arrive to class on time. If you arrive late, then take the first available seat as quietly as possible. If you need to leave early, then please sit near the exit.
- Please attend the entire class period. Leaving class early defeats the purpose of the class period, does not take advantage of resources (i.e., the professor) that can significantly help your learning, and does not build statistical stamina. Please take care of your personal needs (e.g., using the restroom) before class so that you can stay focused for the entire class period.
- Please turn your computer on immediately so that you can promptly begin the daily preparation check.
- Please limit computer use to class work.
- Please turn off and store out-of-sight cell phones and other electronic devices (except for your computer).
- Please do not listen to music (or otherwise wear ear buds) during class.
- Please do not have side discussions while I or others are speaking to the entire class.
- Please do not sleep in class – this is rude and distracting to others.
- Please do not use disrespectful language when addressing others.
Finally, note that the College’s Academic Integrity Statement & Policy will be followed in this course. Please make sure that you are familiar with its content.
Work Outside of Class
As a general rule-of-thumb3, you are expected to spend 2-3 hours of time outside of class for each hour in class. For this course, you will meet for 4.5 hours per week and, thus, you should dedicate between 9 and 13.5 hours of time outside of class time preparing for class, completing assignments, reviewing your work, and asking questions or for help. The work required for this course can be completed within this expected amount of time, if that time is without distraction. If monitoring your phone/device is distracting you from getting your work done then you may consider the aid of apps (e.g., Forest) designed to reduce distractions from devices.4
If you feel that you are spending too much time on some assignments or preparations, then start your work earlier so that you can stop (and do other things) and make plans to seek help).
You may WORK TOGETHER on module preparations and assignments but you must INDEPENDENTLY PRODUCE what you turn in. In other words, you may discuss assignments together and even make plans for how to answer the questions or perform the calculations together, but the calculations must be your own and your written answers must be in your own words. It is also fine to compare independently produced answers as long as you discuss how to correct incorrect answers rather than just copying another person’s answer. Also, note that one need not copy verbatim someone else’s work to violate this policy; i.e., a slight change to someone else’s answer is not acceptable.
If I suspect that you are copying or working “too closely” with another student I will bring this to your attention immediately and discuss this policy with you directly and help develop a strategy to avoid any future problems. In the unlikely event that I suspect further violations of this policy then I will assign zeroes for each assignment (and for each person) for which the policy was violated.
You can NOT work together on the Capstone Assignment. Failure to meet this policy will result in a zero for the capstone assignment.
Please let me know if you have any questions or concerns about this policy.
Title IX Statement
In accordance with Title IX and other local, state, and federal laws, Northland College is committed to providing an environment free of all forms of discrimination, including sex and gender-based discrimination. This includes, but is not limited to sexual violence, sexual harassment, dating violence, and stalking. If you or someone you know has been affected or is currently being affected by these types of behaviors that are limiting your or their ability to participate in this course or any other Northland College sponsored program or activity, please know that there are options, and resources are available. You can also make a report by contacting the Title IX Coordinator.
I am not a confidential resource. As a faculty member I am considered a mandatory reporter and am required to report incidents of sex- and gender-based discrimination and sexual misconduct to the Title IX Coordinator, as we want to ensure that you are connected with the campus support resources offered by the College. You can also make a report by contacting the Title IX coordinator directly. To learn more, please visit the Northland College Title IX website.
As you are aware, the circumstances surrounding COVID-19 are ever-changing. Thus, it is possible that the college may make decisions that will affect how this course is administered. In addition, you may miss some class periods out of an abundance of caution if you are ill. I have designed the course to “work” whether we are face-to-face, remote, or somewhere in between. If you should have to miss class for any reason, please e-mail me promptly to explain to me your situation. I will work with you to help you stay up with class material as best as possible. If face-to-face classes are canceled then I will communicate with you promptly about how we will continue with class. Communication will be key to stay abreast of the current situation and how it relates to our class … so please keep me informed of your circumstances and regularly monitor your Northland e-mail.
It is my hope that we can maintain a face-to-face classroom for the entire session. You can help with this by doing the following things related to our class.
- Get vaccinated.
- Monitor your temperature and check for symptoms of COVID-19 as described under “DAILY SELF CHECKS” on this page. If your temperature is elevated or you have symptoms please don’t come to class, notify the Office of Health Services, and notify me. Being cautious about your health and the health of others will be considered an “excused” absence and will not count against your attendance grade (as long as you communicate with me).
- Thoroughly wash your hands prior to entering the classroom.
- Please properly wear your mask at all times when entering the building and the classroom. This is in compliance with Northland’s face covering policy. 😷
- Maintain proper physical/social distance (three feet) from other students while in the classroom.
- Communicate issues to me (see ways to communicate to me above) so that I am aware and can try to address the issues.
