Tree diagrams screencast

Above is the Tree Diagram screencast as converted and hosted on YouTube. I departed from the script slightly when I was reading over the slides.

I took two complete takes and a couple of false starts to get this 9 minute video done, so, including the script and hacking up the slides, you are looking for an hour to an hour and a half of work. I wish I had added graphics to show the multiplying along the path (see 2:45 minutes into the video), and I originally had a section scripted about why we can treat the probabilities along a path as independent in a non-replacement question – that last point I can add to the worksheet.

Now, as a complete contrast to my screencasting technique, here is an animated video with sing-along about the Mean Median and Mode from
