Course materials
This should accurately show what happened in the past but it might not accurately reflect what will be covered in the future dates. Every problem set is due in class on Friday (one week after it's assigned). You can also find the materials in the course Google Drive.

Course description
We will explore key statistical concepts and probabilistic models motivated through problems and examples from daily life, news articles, and research articles. How do we know that an election result is still 'too close to call'? How did Nate Silver predict the election results so accurately? How does Netflix know what movie we like? Is probability really taken into account into a game of poker by the player? Do dietary supplements actually make us fitter? These questions will be answered from the intersection of statistics and probability. We will cover fundamental concepts such as mean, expected value, variance, conditional probability, regression models, various probabilistic models, hypothesis testing, and decision theory. We will explore how to use these concepts to meaningfully organize, analyze, and summarize the data and draw conclusions to explain phenomena that seem to happen at random.
In addition to theoretical foundation, the course will also emphasize computation and data visualization as a means to convey conclusions or arguments that can be drawn from statistical analyses. We will use statistical programming language R to analyze several real-world datasets and visualize the results as the hands-on component of the course. Students will be able to critically analyze non-traditional data visualization techniques used in the media (infographics) and conventional figures found in scientific articles. At the end of the course, students will become a critical consumer and an effective producer of statistical information.
Textbooks
R In a Nutshell by Joseph Adler (2nd edition)-- This book will be used as reference to aid you with the lab assignments. It will save you a lot of time googling things.
Master Math: Probability by Catherine A. Gorini -- We will loosely follow this textbook. It's inexpensive, readable (without treating you like a dummy), and sufficiently rigorous for our purposes.
Course format and grading
This class is not ye-olde math course, where you sit and write down what's on the board. To keep things interesting, you will be doing a bunch of different things for this class.
- Problem sets (20%). Wendy will be leading the problem session. The first hour, we will be going over some of the problems from the problem set together. The rest of the time will be 'working office hours,' where you can work together and ask the TA questions as they come up. You are required to do the problem set, but you are not required to attend the problem session. However, the attendance will help if your final scores are on the border between two grades (e.g. if you're in between B+ and A-, the attendance will bump you up to A-)
- Lab assignments (25%). The video tutorial and accompanying lab assignments will be posted every other week or so. You will be working on these at your own pace outside of class. For each week, one of you will be assigned to present the result from the lab assignment.
- Tests (50%). There are two midterms (10% each). They are right before we leave for February break and Passover break respectively. The final exam (30%) is cumulative and scheduled by the university. All exams are open notes.
- Lecture, problem session, and discussion (5%). Being a good student will award you this 5%. Show up to class and the problem sessions and this 5% is yours
