Links to each lecture or lab are in the following calendar. They are labelled by their contents. On campus students are welcome to use these if you miss a class or want to see something again.
We anticipate posting videos within 24 hours of the end of lecture or lab.

Aug 31 Question/Answer, use of SAS for randomization tests and t-tests Streaming Video As of 8pm Weds, there was no Echo video (what I normally post). This is a Panopto video. To view this, you will need to login. Your Blackboard login is the same as your ISU Netid and password. If an Echo recording becomes available, I will post those. |
