Week 1 - Probability Review
Overview
Welcome to Week 1! Our goal this week is to (1) help us sort out our varying technologies and workflows and (2) start reviewing statistics and probability. Basically, this the start of a three-week mini-bootcamp to get us ready for the glorious world of regressions!1
What you should do for this three-week unit depends on your background:
I took EC170/STAT141 recently and remember some stuff
- Read through SW, and dig deeper into anything that doesn’t look familiar.
- Watch the class videos and complete video quizzes
- Use the Khan Academy to clarify anything you feel a bit fuzzy on.
- Make sure you can do the practice problems.
Everyone else
- Start by reviewing the Khan Academy videos
- Work through all the Khan Academy practice problems.
- Watch the class videos and complete video quizzes
- Head into the practice problems, and review concepts where you are still stuck.
Reading Guide for Week 1
Chapter 2.1-2.3: Review of Probability
This is the material you should already know, along with supports from Khan Academy ( ). Remember that you don’t need to memorize formulas! Note that most links take you a direct video, but there are also relevant videos in the accompanying playlist.
- SW 2.1 Random Variables and Probability Distributions
- SW 2.2 Expected Values, Mean, and Variance
- You only need a general knowledge of kurtosis and skew.
- Transforming random variables
- SW 2.3 Two Random Variables
- Law of iterated expectations can be skimmed
- Make sure you’re good with key concept box 2.3!
- Combining random variables
- Law of iterated expectations can be skimmed

Sorry that the audio is bit fuzzy at the beginning - I was still learning!
Aside: This unit will pull from lots of resources. Things will be simpler once we get to chapter 4 and onward↩︎
