ENVS 491-001 – Environmental Applications of Statistics
3 Credits, Summer 2019
MTWR, 1-2:40pm Trani 250
Instructor: Dan Albrecht-Mallinger
Office: Life Sciences, Room 106
Office Hours: M/W 3-5pm, R 9-11am, or by appointment
Course Dates & Absence Policy: This class runs from 10-June to 18-July. Friday, 14-June is the deadline to submit intended absences for religious observation. Add/drop is 11-June (sorry, not a lot of time there), and the last day to withdraw from the class is 28-June. For an absence to be excused for medical or personal reasons, students must email instructor no later than 24-hours following the absence, with advanced notification strongly preferred. Three unexcused absences will result in the failure of the course.
Texts: All required readings will be available on the course Rampages site as downloadable PDFs. Student library fees are ~$70 per semester. these fees fund the university’s intellectual in fracture, including access to academic databases. Readings for this course will be drawn from library resources.
Hardware & Software:
- All students are required to bring a functioning laptop to class. If you do not have access to a laptop, contact the instructor to coordinate a semester laptop checkout.
- All students are required to have Microsoft Office Suite (free to download with your VCU student credentials).
- All students are required to download and install Program R and RStudio.
Point Breakdown: Assignments will make up 80% of your grade. All assignments are to be submitted to Blackboard; late assignments will be accepted up to 48-hours following the deadline for a flat -10% penalty. Summer Innovation Collaborations (SICs!) will account for the remaining 20% of course grades.
With that boilerplate out of the way, what is this course about?
Thanks for asking! There are 4 goals for this coarse.
- To review and learn the foundational concepts in statistics (central tendency, variance, probability, populations, sampling, bias, etc.).
- To apply statistical tests to real-world environmental data and draw meaningful inference.
- To become proficient in data types, data management, and data analysis in the computing environs of Program R.
- To practice collaboration by sharing insights and inquiry.
So what does that actually look like?
We have six weeks to learn a whole lot–and as luck would have it, we are scheduled from 1-2:40pm…our biologically-preset siesta time. In spite of natural inclinations to nap, we will learn a skill, apply that skill, and then critically interpret our applications each session.
You will then be responsible for summarizing the application in a write-up, which will be due before the next class. Most days, you will leave class with a rough draft of the write-up already in hand; ideally, it will only take a single proof-reading before you can submit it.
The majority of our applications will be in Program R, which is a command-line program for statistics and data science. Learning a new programming language is much like learning any other language: you’ll make lots of mistakes, but you’ll learn from them faster through practice with others. A misplaced comma or lowercase letter may stymie you for hours, but a quick glance from a classmate can identify the problem in seconds. Your peer may struggle with a command’s syntax, but you can help talk them through it.
The class will work best when people show up ready to learn and to help one another learn. We’ll be working with a broad set of public environmental data–carbon emissions, lead exposure, biodiversity counts, etc.–and no one will be an expert on everything. You will each have an insight to contribute, so believe in yourself, and believe in one another!

DSS: All individuals deserve the opportunity to participate to their fullest capacity at VCU. If you have been diagnosed with a disability, or suspect you may be struggling with a disability, please do not hesitate to communicate with Disability Support Services. If you require accommodations approved by the DSS, you or the DSS office must notify me by email or in person to determine what accommodations will be required for you to succeed in this course, clearly defining student, peer, & instructor expectations.
Respectful Participation: This course will be applications-based, with frequent opportunities to debate and discuss. This does not represent a license to demean, diminish, or ostracize your peers based on their perspective or their person. You do not need to condescend to express skepticism; nor do you need to pillory to disagree. The best way to test ideas is by inquiry: whenever possible, ask questions in lieu of rejecting another’s stance out-of-hand. Above all, address everyone with respect: use the name and pronouns of their preference; 2nd person pronouns are great work-around when you’re unsure of either..

Student email standard: Email is considered an official method for communication at VCU. Students are expected to check their official VCU email on a frequent and consistent basis (the university recommends daily) in order to remain informed of university-related communications. Students are responsible for the consequences of not reading, in a timely fashion, university-related communications sent to their official VCU student email account. Mail sent to the VCU email address may include notification of university-related actions, including disciplinary action. Students must read this standard in its entirety at https://ts.vcu.edu/media/technology-services/content-assets/university-resources/ts-groups/information-security/StudentEmailStandard.pdf
Student financial responsibility: Students assume the responsibility of full payment of tuition and fees generated from their registration, all charges for housing and dining services and other applicable miscellaneous charges. Students are ultimately responsible for any unpaid balance on their account as a result of the University Financial Aid Office or their third party sponsor canceling or reducing their award(s).
Students representing the university – excused absences: Students who represent the university (athletes and others) do not choose their schedules. All student athletes should provide their schedules to their instructors at the beginning of the semester. The Intercollegiate Athletic Council strongly encourages faculty to treat missed classes or exams (because of a scheduling conflict) as excused absences and urges faculty to work with the students to make up the work or exam.
Students with disabilities: Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, as amended, require that VCU provide “academic adjustments” or “reasonable accommodations” to any student who has a physical or mental impairment that substantially limits a major life activity. To receive accommodations, students must register with the Office of Student Accessibility and Educational Opportunity on the Monroe Park Campus (828-2253) or the Division for Academic Success on the MCV campus (828-9782). Please also visit the Student Accessibility and Educational Opportunity website via https://saeo.vcu.edu/ and/or the Division for Academic Success website via https://das.vcu.edu/ for additional information.
Once students have completed the registration process, they should schedule a meeting with their instructor (s) and provide their instructor (s) with an official accommodation letter. Students should follow this procedure for all courses in the academic semester.
Withdrawal from classes: Before withdrawing from classes, students should consult their instructor as well as other appropriate university offices. Withdrawing from classes may negatively impact a student’s financial aid award and his or her semester charges. To discuss financial aid and the student bill, visit the Student Services Center at 1015 Floyd Avenue (Harris Hall) and/or contact your financial aid counselor regarding the impact on your financial aid.
Faculty communication about students: VCU instructional faculty, administrators and staff maintain confidentiality of student records and disclose information in accordance with the Family Educational Rights and Privacy Act (FERPA). This means that VCU officials may disclose student record information without the consent of the student in certain situations. To support university operations, for example, VCU officials share information about students with other educational officials as necessary to perform their job duties. FERPA permits this disclosure to school officials who have a legitimate educational interest in the student information. In addition, VCU officials have obligations to report information shared by a student depending on the content of that information, for example, in compliance with VCU’s policy on the duty to report. Unless FERPA permits a certain disclosure, VCU generally requires consent from a student to disclose information from their education record to another individual. You may find additional information on the VCU FERPA website: http://rar.vcu.edu/records/family-educational-rights-and-privacy-act/.
