Notes on designing an experiment

Waking Example

A psychology course has the 21 students shown below. The professor wants to use the students to test two new types of pill for keeping people awake, called Wakey-Wakey and Zizzaway. He has only six pills of Wakey-Wakey and five pills of Zizzaway. He plans to use 11 students. Each student will be shut alone in the observation room, swallow their allocated pill, and then follow a set programme of activities until they fall asleep. A hidden watcher will record when they swallow the pill and when they fall asleep. Design the experiment for the professor, to the extent of giving him a plan allocating pills to students.
