DTSA 5012 ANOVA and Experimental Design

Instructor Brian ZaharatosÌý

Course DescriptionÌý

This second course in statistical modeling will introduce students to the study of the analysis of variance (ANOVA), analysis of covariance (ANCOVA), and experimental design. ANOVA and ANCOVA, presented as a type of linear regression model, will provide the mathematical basis for designing experiments for data science applications. Emphasis will be placed on important design-related concepts, such as randomization, blocking, factorial design, and causality. Some attention will also be given to ethical issues raised in experimentation.ÌýÌý

  • Use peer feedback, self-reflection and video analysis to improve collaboration skills.Ìý
  • Create reproducible statistical workflows.Ìý
  • Act ethically in the role of professional data scientist.ÌýÌý

Drops, Tuition Refunds, and WithdrawalsÌý

Because the MS-DS has flexible course start dates, all drops, tuition refunds, withdrawals and grades are handled at the individual course level. It is the student’s responsibility to monitor these deadlines. Coursera and Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder are not responsible for notifying the students of these deadlines. For approximate session timelines, access the Boulder MS-DS Onboarding Course via the MS-DS degree homepage. To drop or withdraw from a course please complete the appropriate form on the Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder Office of the Registrar website.ÌýÌý

Drops and RefundsÌý

Each student has 14 days from a class start date or their enrollment date (whichever is later) to request a drop for 100% tuition refund. Students are only eligible to drop a course if they have not accessed the restricted content (timed proctored exam) or received a grade.Ìý When a course is dropped under these conditions, it will not appear on the student’s record.Ìý

WithdrawalÌý

Students who request to drop the course after the 14-day period and who have not accessed the timed proctored assessment may withdraw from the course but will not receive a refund. When a student withdraws from a course under these conditions, the student will receive a grade of W on their academic record. W grades have no bearing on the GPA and credit total.Ìý

Students who access a timed, proctored final exam are ineligible for a drop, withdrawal, or refund, and are assigned a grade.Ìý

Program PoliciesÌý

Suspected Violations of AI Tool Usage PolicyÌý

If program staff suspects you may have used AI tools to complete assignments in ways not explicitly authorized or suspect other violations of the honor code, they will contact you via email. Be sure to respond promptly to any related communication so your perspective is included in the case review. Failure to respond timely will not prevent the completion of a case review.ÌýÌý

In suspected cases of unauthorized AI tool usage, the program may:Ìý

  • Request the documentation noted above (see AI Usage Documentation Guidelines) or other supplementary materialsÌý
  • Issue a warningÌý
  • Assign a 0–50% grade for the questionÌý
  • Assign a 0–50% grade for the assignmentÌý
  • Assign an F grade for the courseÌýÌý
  • Reference prior violationsÌý
  • Remove access to the course, related materials, and toolsÌý

Turnitin and similar AI detection tools may be used in these courses for initial detection of possible honor code violations. All suspected violations will be reviewed by a human. AI tools alone will not be used to determine if an assignment is plagiarized, and results from these tools will not be used alone as evidence to penalize students.Ìý

University PoliciesÌý

Accommodation for DisabilitiesÌý

If you qualify for accommodations because of a disability, please submit your accommodation letter from Disability Services to your faculty member in a timely manner so that your needs can be addressed. Disability Services determines accommodations based on documented disabilities in the academic environment. Information on requesting accommodations is located on the Disability Services website. Contact Disability Services at 303-492-8671 or dsinfo@colorado.edu for further assistance. If you have a temporary medical condition, see on the Disability Services website.Ìý

Classroom BehaviorÌý

Students and faculty each have responsibility for maintaining an appropriate learning environment. Those who fail to adhere to such behavioral standards may be subject to discipline. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with race, color, national origin, sex, pregnancy, age, disability, creed, religion, sexual orientation, gender identity, gender expression, veteran status, political affiliation or political philosophy. Class rosters are provided to the instructor with the student's legal name. We will gladly honor your request to address you by an alternate name or gender pronoun. Please advise us of this preference early in the semester so that we may make appropriate changes to my records. For more information, see the policies on and the .Ìý

Honor CodeÌý

The Âé¶¹Ãâ·Ñ°æÏÂÔØ takes issues of academic dishonesty extremely seriously.ÌýÌý

Students in all of Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder’s courses, whether not-for-credit or for-credit, are expected to perform to the highest standards of academic honesty.ÌýÌý

Students enrolled in for-credit courses are members of the Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder’s community and are subject to the Honor Code Office’s policies and procedures. Information on the Honor Code can be found at the Honor Code Office website.ÌýÌý

Students who violate the Honor Code are subject to discipline. Violations of the policy may include: plagiarism, cheating, fabrication, lying, bribery, threats, unauthorized access to academic materials, submitting the same or similar work in more than one course without permission from all course instructors involved, and aiding academic dishonesty. Students are specifically expected to turn in original work and cite portions created by other authors. If a student has doubts regarding what collaboration is permissible in the course, the student should consult the discussion forums or the course facilitator directly.Ìý

Sexual Misconduct, Discrimination, Harassment and/or Related RetaliationÌý

Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder is committed to fostering a positive and welcoming learning, working, and living environment. Âé¶¹Ãâ·Ñ°æÏÂÔØBoulder will not tolerate acts of sexual misconduct (including sexual harassment, exploitation, and assault), intimate partner violence (including dating or domestic violence), stalking, protected-class discrimination or harassment by members of our community. Individuals who believe they have been subject to misconduct or retaliatory actions for reporting a concern should contact the Office of Institutional Equity and Compliance (OIEC) at 303-492-2127 or cureport@colorado.edu. Information about the OIEC, university policies, reporting options, and other resources can be found on the.Ìý

Please know that faculty and instructors have a responsibility to inform OIEC when made aware of incidents of sexual misconduct, discrimination, harassment and/or related retaliation, to ensure that individuals impacted receive information about reporting options and support resources. This applies regardless of where or when an incident occurs as long as it involves a member of the Âé¶¹Ãâ·Ñ°æÏÂÔØcommunity.Ìý

Religious HolidaysÌý

Campus policy regarding religious observances requires that faculty make every effort to deal reasonably and fairly with all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance. Since this is an online class, with no fixed weekly calendar schedule, we ask that you arrange your workload to accommodate your religious practice. See the for full details.Ìý
