3 COURSE MATERIALS
There is no specific textbook for this course. Instead, readings will be drawn from a number of sources – mainly online textbooks but sometimes blog posts and other resources. All of these sources are freely available online. The links for each reading appear in the course reading list.
4 COURSE OBJECTIVES
The aim of this course is to develop students’ basic data literacy skills by learning to use a data-driven approach to think critically about data. Students will develop statistical knowledge via sampling data from real and simulated datasets, visualizing their results, testing for relationships in their data, and interpreting the patterns they see. The class will extend basic data science training by teaching students to code their own statistical tests and visualizations in Python.

5 EVALUATION
Lab/Homework Assignments 15%
Statistics in the News Project 15%
Midterm Exam 32%
Final Exam 38%
The evaluation and testing formats for this course were created to assess the learning objectives as listed in section 4 and are necessary for meeting these learning objectives.
Bi-weekly Lab/Homework Assignments (15%):
*** This assessment has flexible deadlines. It is exempt from the academic considerations policy. ***
For each lesson, you will complete a set of lab and homework problems in a Jupyter Notebook. The lab elements will be guided by video tutorial. The homework problems you will do on your own. The homework problems will be based on the lecture material for the lesson and will also relate to the corresponding lab material. The Jupyter Notebook with the lab/homework assignment will be released on OWL on the same day as the video tutorial it corresponds with (Mondays of the release week at 9am). It will be due 12 days later, on Friday at 5:00pm. You must upload the Notebook (‘.ipynb’ extension) to the assignment portal on Gradescope. You are responsible for uploading the correct file, in the correct format to the correct portal on Gradescope. If you upload the file incorrectly, you will receive a mark of 0. There are a total of 6 assignments that you will complete over the course of the term. I will drop your lowest score, which means that you can skip one assignment without penalty. Each of the remaining 5 assignments will count toward 3% of your grade. The solution to the assignment will be released the Monday after the assignment is due at noon. If your assignment has not been submitted before the solution is posted, you will receive a grade of 0. There will be absolutely no exceptions to this policy.
Statistics in the News Project (15%):
We frequently see statistics reported in the news. But are they noteworthy? Or not worthy of the space they take up? The goal of this assignment is to critically evaluate a statistical claim reported in a media outlet. You should select a statistic that is interesting to you but that sounds a bit too good/weird/unusual/outlandish be true. The statistic should also have a clear source citation (e.g., a research article published in a scientific journal, upon which the news story is based). You should then critically evaluate the claim, as well as the original source article, using evidence from both sources. Write a 280-character “Tweet” style report that states your conclusions about the news article, relative to your evaluation of the source article. Additional details and rubric are available in the resources section on OWL.
Exams (70%): There will be two proctored exams in the course. These exams will take place in person. The midterm will cover the course material from weeks 1-5. The final will be cumulative (weeks 1-12).
*** Final Exams are always exempt from the academic considerations policy. ***
*** The Midterm Exam is the designated course component that is exempt from the academic considerations policy. ***
Both exams will be closed book/closed note. No calculators or other devices will be allowed. You will be allowed one “cheat sheet” of notes for the midterm and two cheat sheets for the final exam. Your cheat-sheet(s) may include any course material that you think will help you on the relevant exam and you may use both the front and back sides of each paper. Each cheat sheet may not include more than a single piece of “letter” sized paper (no stapled, glued, or taped elements are allowed) and all your notes must be entirely handwritten (no photocopies, pictures, or printouts will be allowed). Your cheat sheet(s) will be checked by the proctors. If they are found to be in violation of the requirements the proctors will confiscate them during the exam. The exams will include multiple-choice/select all that apply/matching/fill in the blank questions, along with several short answer, and graph/code interpretation questions.
The midterm will be completed during class time on Wednesday, 30 October (11:30am to 1:30pm). You will have the class period to complete it. The final exam will be scheduled by the registrar during the December exam period. It will be 3 hours long. If you are an accommodated student, your time will be adjusted according to the time listed in your official accommodation if and only if you request an exam via the accessible education office. You MUST take the exams independently. The answers on the exam must be entirely your own work. If there is evidence that you worked with another student on the exam or that the work is not entirely your own, you will receive a score of 0.
Extra Credit (OPTIONAL; up to +3%): Statistics is a discipline that relies on the analysis of empirical data. You have the chance to participate in this process by helping to generate research data. To take part, you will be given access to the SONA system, and you may participate in any “for credit” studies that you wish. You will receive bonus credits added to your overall course grade for each SONA credit you earn, to a maximum of 3.0 SONA credits (50% of these credits must be earned in in-person, rather than online studies). However, the bonus will only be added if you have achieved a passing course grade without any bonus credit – in other words before bonus credits are added you must get at least 50% on the regular coursework/exams. Note that if you sign up for a study and then fail to attend, you will receive a penalty equal to the number of study-credits the original study was worth. This penalty will count against your earned credits until it is made up.
The SONA system will track the studies you complete, and I will be given this information at the end of the term. No grade adjustments will appear until after the final grade has been calculated. This is an opportunity to earn extra credits and is not required as part of your normal grade, you will not lose any marks if you do not participate in research studies. If you wish to earn extra credit but do not wish to participate in studies, more information about an alternative assignment will be available on OWL. The maximum number of bonus credits you may earn is 3.0. For each credit you earn, you will receive an additional 1% in the gradebook. All extra credits must be completed by 11:55AM (just before noon) on the last day of term to count toward your grade. Because this item is extra credit and will never count against you, there will be absolutely no exceptions to this deadline. *** Because this is not an official assessment and is not required, it is exempt from the academic considerations policy. ***
POLICY ON MISSING COURSEWORK
Weekly Lab/Homework Assignments: Assignments are due at 5:00pm on Friday evening of the week they are due (see schedule below). The solution to the assignment will be released the following Monday at noon. The grace period for assignment submission is until Monday at noon. Please ensure that you give yourself enough time to complete your submission by this time. There is no need to email the course staff about late homework, as the submission portal will remain available until the answer key is released (Monday of the relevant week at noon). If your assignment has not been completed and correctly uploaded by the time the answer key is released, it will receive a score of 0. Because the assignments are worth only 3% each, there is a grace period between the due date and assignment submission portal closure, and the lowest score is dropped, I will not accept any excuses for missed assignments. If you have a long-term illness or other issue of concern, please contact academic counselling in your home faculty with appropriate documentation to request relief.
Statistics in the News Project: The project will be due at 11:55pm on Wednesday 4 December. If you wish to attest to an illness or other extenuating circumstance, you may do so using the appropriate reporting portal. If you attest to an illness or other short-term extenuating circumstance, your assignment will be due 24 hours after the deadline to make an attestation. With a signed attestation, the project will be due on Saturday, 7 December at 11:55pm. You must upload the completed assignment to the assignment portal before that deadline or you will receive a score of 0.
Exams: If you need to miss an exam due to illness or other issue, you MUST request relief from academic counselling. Without an approved consideration from academic counselling, you will receive a score of 0 the exam. There will be one opportunity to make up the final exam. The make-up final exam will be held on a date and time in January that will be announced in class. Note that the make-up exam may include new test questions. The practical component of the make-up exam will include a Jupyter notebook that you will complete on your own computer. Note that if you miss the make-up exam, your next opportunity to take the final exam will be during the finals period the next time the course is offered. You must have the approval of the Associate Dean (Undergraduate) to use this option.
You will NOT have an opportunity to make up the midterm exam. Instead, if you have an approved consideration for the midterm, you will receive a midterm score based on the items on the final exam that cover the same content as the midterm. Your proportion correct on these items will be used to calculate a midterm score for you. Your final exam score will then be calculated based on the proportion of items you get correct that cover content from the second part of the course.
The expectation for course grades within the Psychology Department is that they will be distributed around the following averages:
70% 1000-level to 2099-level courses
72% 2100-2999-level courses
75% 3000-level courses
80% 4000-level courses
The Psychology Department follows Western’s grading guidelines, which are as follows (see: https://www.uwo.ca/univsec/pdf/academic_policies/general/grades_undergrad.pdf
A+ 90-100 One could scarcely expect better from a student at this level
A 80-89 Superior work that is clearly above average
B 70-79 Good work, meeting all requirements, and eminently satisfactory
C 60-69 Competent work, meeting requirements
D 50-59 Fair work, minimally acceptable
F below 50 Fail
In the event that course grades are significantly higher or lower than these averages, instructors may be required to make adjustments to course grades. Such adjustment might include the normalization of one or more course components and/or the re-weighting of various course components.
Policy on Grade Rounding
Please note that although course grades within the Psychology Department are rounded to the nearest whole number, no further grade rounding will be done. No additional assignments will be offered to enhance a final grade; nor will requests to change a grade because it is needed for a future program be considered.
