Saving data: If you’re using classroom computers, use Flashdrives or UNM’s OneDrive (available in LoboMail) for saving files. The CTLB computers do not connect to your standard UNM drive space. I recommend using a very systematic folder structure, such as ADA1/HW, ADA1/Class, ADA1/Reading, ADA1/Poster, etc. Do not just work on files in your downloads folder or your desktop; respect your data and code!
Timetable
Each week has this structure:
 Preclass (Tuesday): Reading, Video, Quiz (due before class — solutions become available Tue 3:30, after the quiz is due)
 Inclass: Activities in class Tuesday and Thursday due by 5pm each day, submitted to UNM Learn (evaluated by TA within 1 week).
 Postclass (Thursday): Homework (crowdgrader, due following Thursday before class)
 Postclass (Following ThursdayTuesday): Grading (crowdgrader, following 1 week + Tuesday before class)
UNM Learn for content, YouTube Video playlist (try 1.5 speed, then pause as you need).
Video: Upgrading R on Windows.

Student learning outcomes
At the end of the course, you will be able to: (student results: R, all years, 2015, 2014, 2013, 2012)
General outcomes:
 Organize knowledge in graphs, tables, and code to support concise, comprehensible, and scientifically defensible written interpretations to produce knowledge within a reproducible research environment.
 Distinguish a testable scientific hypothesis or datasupported interpretation from an opinion.
 Understand from a data story the goals of the study and apply the correct statistical procedure.
 Explain the scientific aspects of a problem to nonscientists in a fashion that enhances understanding and decision making.
Topical outcomes:
 Define parameters of interest and hypotheses in words and notation.
 Summarize data visually, numerically, and descriptively and interpret the observed characteristics. Calculate and interpret numerical summaries such as mean, variance, fivenumber summary, confidence intervals, and pvalues, and create visual summaries such as bar plots, scatter plots, and histograms. (Never pie charts!)
 Distinguish between statistical significance and scientific relevance.
 Use statistical software, such as R, to read and manage data, create informative plots, report numerical summaries, and apply statistical models, by recommended programming practice including abstraction and documentation.
 Understand the differences and limitations of controlled experiments and observational studies. Design experiments to infer causal treatment effects. Analyze observational data to infer associations between measured variables.
 Identify and explain the statistical methods, assumptions, and limitations used in reported studies in scientific literature or popular media.
 Evaluate and criticize published studies, the work of peers, and your own work and assess what was done well, what could be done better, and examine whether their conclusions are supported using statistical principles.
 Make evidencebased decisions by constructing and deciding between testable hypotheses using appropriate data and methods.
 Discover relationships and make predictions through model development and selection.
Meeting the learning outcomes
You will acquire new information in this class, but the emphasis is comprehending, integrating, and applying information. Rote factual memorization is the lowest form of learning. Effective learning takes place by explaining, integrating, applying, and analyzing facts, hypotheses, and theories.
Learning in this class occurs by:
 Doing – completion of exercises that require analysis of data to answer questions and test hypotheses, or researching answers to reading assignments.
 Discussion – interaction with classmates to assemble and synthesize information you’d utilizing the collective skills and knowledge base of the group.
 Listening, acting, and reflecting – activities during class time provide insights into information not available in readings and includes review difficult material to aid comprehension. Note taking permits later reflection on lecture content. Listening to the professor lecture is the least effective learning tool for both students, however, and you should plan on coming to every class prepared to participate in active and reflective learning opportunities.
Assessment
 Quizzes will be due each Tuesday before class. Purpose: to assess reading and video comprehension and assure you’re prepared to actively participate in class activities with minimal lecture. (About 12, 20% of final grade, the lowest few are dropped.) Most weeks plan for 12 hours reading and video, 20 minute quiz.
 Inclass assignments are due each day by the end of day (midnight), submitted to UNM Learn. Purpose: to struggle and find success in class with the concepts and skills. (About 24, includes class participation, 20% of final grade, the lowest several are dropped.) Most weeks plan to finish in class.
 Homework (HW) assignments are assigned each Thursday and due the following Thursday, submitted to crowdgrader.org (75% of HW grade). Purpose: to apply concepts and skills to your class poster project. (About 12, 40% of final grade, the lowest few are dropped.) Most weeks plan on 14 hours per assignment.
 Peer grading is due by the following Tuesday after each homework is due (25% of HW grade). Purpose: to gain skill assessing the work of others, as well as see alternative strategies to answer questions. Most weeks this will take about 30 minutes to grade 5 other students’s HW.
 Poster will be developed through semester (most HW assignment contribute to poster), the last couple weeks we’ll complete them, and the last week we’ll have poster presentations. Purpose: to have an overarching set of questions to answer using methods learned in the course, with a deliverable you can be proud of! (1 poster and presentation, 12% poster, 2% presentation, and 2% evaluations of others of final grade.) In the last couple weeks, assembling this poster may take 35 hours, using a template provided to you.
 Course surveys are due at the beginning and end of the course. Purpose: to participate in national projectbased learning projects and improve course. (About 2, 4% of final grade.)
Final grade may include a small buffer at the discretion of the instructor. For example, final grade could be the total points earned divided by the total possible points times 0.95 for graduate students and 0.90 for undergraduate students. That is [Final Grade] = [Points Earned]/[Points possible * 0.95], so that your grade is slightly higher than you earned.
Final grade calculation: (so much rounding up!)
I’m really proud of my class; you’ve worked hard this semester in a new format. I was especially pleased with the closing poster session, a celebration of what we were able to accomplish.
 Drop lowest 4 inclass, 2 quizzes, and 2 homework assignments (your worst two weeks).
 Take weighted average as discussed above.
 Divide ugrad grade by 0.95 and grad grade by 0.98 (a little extra boost for ugrads).
 Round this number up to the nearest integer (93.1 becomes a 94).
 Assign letter grades with this these cutoffs (get’s lenient below a B)
Grades  
Letter  at least 
A+  97 
A  94 
A  90 
B+  87 
B  84 
B  80 
C+  75 
C  71 
All homework assignments in this class are electronic, submitted to crowdgrader.com for grading, except for the final poster.
Crowdgrader:
 Students usually get far more feedback on their work than they would get from overworked teaching assistants/faculty.
 Students get to see what other students are doing, and they can learn from the work of others (taking the best ideas, and leaving the rest).
 In exchange for this, they need to put in some amount of work in reviewing the work of others.
 It is important that students understand that their final grade is determined both by the quality of their work, and by the precision of the grades they give, and the helpfulness of the reviews they write.
Late assignments will not be accepted.
Rubrics guide assessment (and selfassessment) of homework, code, projects, exams, and presentations. Each assignment will have its own specific rubric.
All R code for the assignment should be included with the part of the problem it addresses (for code and output use a fixedwidth font, such as Courier).
Do NOT use your R code and output as your answer to the problem, but include them to show me how you arrived at your answer. Your prose solution (in a nonfixedwidth font) should be provided in addition to R output.
Collaboration and citation
For homeworks I encourage you to work together. Please discuss the data, code, and problems with one another, but do your own exploration and write up. We expect everyone to hand in substantially different homeworks, and we will enforce this under the honor code. The small benefit you might get from plagiarism is not worth the severe penalty (of lost trust, being reported to the dean, no points for the assignment, etc.).
As in life, please use any resources available to you. Projects and some homeworks will explicitly encourage you to use resources on the internet, but showing extra initiative will always be appreciated. You may find R programming tough at first, so feel free discuss your problems with other classmates or meet with or email questions to the TAs or me.
I encourage you to use the ideas of others, but make them your own, giving credit. For projects have a formal bibliography, for homework cite casually, and for code simply copy the URL in as a comment (which is doubly helpful for finding the resource again).
Disability statement
If you have a documented disability that will impact your work in this class, please contact me to discuss your needs. You’ll also need to register with the Accessibility Resource Center in 2021 Mesa Vista Hall (building 56) across the courtyard east from the SUB.
Peer mentor Carrie Booth <boothc@unm.edu>, Education grad student, course alumnus, and member of the Delta Alpha Pi Honor Society (Disability Achievement Pride) has a background in special education and is familiar with challenges surrounding learning and accessibility for students with disabilities in college. She has offered to be available, if you choose to seek her out, for assistance. I legally can’t connect her to you, but you can let her know if you have needs she’ll be particularly qualified to be helpful with. I’m glad to have her available since one of her goals through DAP is to reduce stigma of students with disabilities in academia through visibility, achievement, and community service.
Our Classroom
We’re doing this because:
 We want you to be empowered with statistics.
 We believe everyone should get out of this course with awesome skills
 Realtime feedback promotes efficient learning
“It encourages me to engage actively with the course material and take responsibility for my learning.”
GAISE Connections
Our six recommendations include the following:
 Emphasize statistical literacy and develop statistical thinking
 Use real data
 Stress conceptual understanding, rather than mere knowledge of procedures
 Foster active learning in the classroom
 Use technology for developing conceptual understanding and analyzing data
 Use assessments to improve and evaluate student learning
Learning without thought is labor lost.
What I hear, I forget.
What I see, I remember.
What I do, I understand.
