Welcome!

431 is the first part of a two-semester sequence (with 432) in applied statistics and data science taught by Professor Thomas Love in the Department of Population and Quantitative Health Sciences at Case Western Reserve University.

Everything will be linked here

Materials you will find here include:

  • the course syllabus
  • the course calendar, which will provide the final word on all deadlines, and will also link to all materials used in each class session
  • Dr. Love’s course notes, which are a major source of course examples
  • detailed information on all course assignments, including labs, minute papers, projects and quizzes, with all deadlines found in the Calendar.
  • information on software, including installation instructions for R, RStudio, the key R packages and data sets we’ll use
  • information on how to contact us.

Adjustments to these materials will occur over the course of the semester. Professor Love will highlight any major changes in class.

Getting Started

Your first few steps in this course are to:

  3. Skim through the Course Syllabus.
  4. Obtain a copy of David Spiegelhalter’s The Art of Statistics: How to Learn from Data, originally published in 2020 and available at all major book retailers for around $20.
  5. Complete the Welcome to 431 survey, as described below.
  6. Get started installing the software you’ll need for the course.
  7. Sign up for the (free) Campuswire discussion forum.

Pep Talk!

Learning R can be difficult at first - it’s like learning any new language. Hadley Wickham, the chief scientist at Posit (makers of RStudio) and the author of some amazing R packages you’ll be using like ggplot2 made this wise observation:

It’s easy when you start out programming to get really frustrated and think, “Oh it’s me, I’m really stupid,” or, “I’m not made out to program.” But, that is absolutely not the case. Everyone gets frustrated. I still get frustrated occasionally when writing R code. It’s just a natural part of programming. So, it happens to everyone and gets less and less over time. Don’t blame yourself. Just take a break, do something fun, and then come back and try again later.

If you’re finding yourself struggling or not understanding, take a break, talk to classmates, ask us for help, etc. If you’ve spent 15 minutes working on something and are stuck, don’t keep working on it, and instead ASK FOR HELP. I promise you can do this. (Thanks, Andrew Heiss)
