Video 8.1The Idea of a Random Variable

You should always watch videos for this class with a notebook out – get one out now, to get yourself ready for this video. You should be ready to write down things you learn, and/or to pause the video when needed to work something out. When you finish watching the video, you should write a summary of what you've learned and what it made you think about.

This video is 9 minutes long. Most people spend more time watching a video than the official length of a video – plan on pausing the video from time to time to think about a question, to write down some notes, or to work through a problem on your own.

There may be times when you don't understand something that comes up in a video. Write those questions down – at the end of the week, go back over your notes and make sure they've been addressed to your satisfaction.
