Class22: Video
We will watch a video on surveys and sampling. Then Laurie will talk about variance and give some alternatives to box models.
On Friday, April 5, we will meet in McCosh 66 (during regular class hours 11:00 - 11:50) to use the computer equipment again. We hope by then to have the data on (Scottish) sperm quality used in the British Medical Journal article.
