431 Course Main Page: Fall 2025
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.
Getting Started
Your first few steps in this course are to:
- Register and enroll via the CWRU Student Information System (SIS).
- Be sure to register for PQHS 431 unless you are part of the Clinical Research Scholars Program (in which case, register for CRSP 431) or you are part of the MPH program (in which case, register for MPHP 431.)
- Take a look at this website. Of particular importance is the Getting Started section you’re reading now, and the Course Calendar, but a lot of other material is available now, and more will appear as we approach the first day of this class, which will be on Tuesday September 2.
- Note that we will not meet on August 26 or 28, as Dr. Love will be away because of a family issue.
- 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 less than $20.
- Visit https://bit.ly/431-2025-welcome to complete the Welcome to 431 Survey, which is your first assignment.
- Note: You must log into Google via CWRU in order to access the Survey.
- The survey is technically due at noon on Wednesday 2025-09-03, but should be completed as soon as you can
- Before our first class, I also suggest you get started reading the first few sections (particularly the Introduction and Sections 1-2) of the online book R for Data Science, 2nd Edition.
- Before our second class, on September 4, you’ll need to get R and RStudio on a computer you can control (including installing regular updates to the software) for the semester.
- Please start this process now - installation details are found on our 431 Software page.
- Please visit this link for information on how to record a pronunciation of your full name in the Student Information System so that all of your instructors (and fellow students) will be able to hear it.
- After our first class on September 2, you will need to log into Google via your CWRU account and ensure that you have access to a Shared Folder called 431 Fall 2025 Students and Dr. Love.
