Keep Up With The Work!

  • Learning good writing skills requires time and practice.

  • If you wait until the last minute to write, you can’t revise and practice.

  • This course is paced to give you enough time to revise your work… intentionally.

Projects

  • Scaffolded with homework assignments

  • Fix things I comment on w/ homework!

  • Late work will NOT be accepted without

    • major life events of >2 week duration AND
    • evidence of engagement with the assignment before the event occurred
  • Project presentations will be scheduled during Week 15 and Finals

    • IF presentations get done during Week 15 then we won’t meet for the final
  • Do NOT make travel plans for the end of the semester

User Guide

  • Translate a statistics topic into a practical guide for how to do something

    • What is required to begin? data, etc.
    • What steps need to be taken?
    • How should the results be presented/interpreted?
  • Practice thinking about audience needs and planning scope

    • Think about trying to learn a package based on a sparse vignette that doesn’t address your use case… and prevent that.
  • Takes more time to understand the topic than you think – start early.

  • Rough Draft due February 27 at 6pm

  • Final version due March 5 at 6pm

Business Report

  • Address a statistical question of interest to a business

    • Most of these are somewhat based on my time in industry
  • Find and document relevant data

  • Explain and document your analysis

  • Draw a conclusion and explain that to a non-statistician

  • Make a presentation

  • Rough Draft due April 17 at 6pm

  • Final written report due May 1 at 6pm

  • Presentations in-class April 27, April 29, May 8 (if necessary)

Evaluation Criteria

In addition to the rubric:

  • Grammar and spelling
  • Ability to communicate effectively
  • Intellectual engagement
  • Demonstrated understanding of the material

Simple, elegant solutions > unnecessary complexity

AI

  • The goal of writing classes is to improve your ability to reason… the writing is a side effect

  • AI cannot think/explain/reason – it only predicts the next likely word probabilistically

  • Do NOT use AI as a replacement for doing work. Querying to explore your understanding is probably fine, using it to write or think for you is not.

  • I would rather read something with typos and grammar issues than something that sounds like it’s from AI and not your thoughts.

Evaluation Criteria

Any use of generative AI must be disclosed in an appendix to your submission

You must document the following:

  • the version of the generative AI used (e.g. Claude Sonnet 4.5, GPT 5.2, Copilot GPT-5 chat)
  • the full sequence of prompts and responses
  • any additional inputs you provided to the AI system (documents, images, etc.)
  • a “diff” between the AI responses and your submission, showing exactly what was generated by the AI system and what you changed.

Oral Exams

  • Be prepared to explain your writing process, your approach, and your code

  • Oral exams on the assignment can be used to replace the assignment grade at my discretion

    • This is not intended as punishment – it helps at least as often as it hurts
  • Policy applies to homework and projects
