• 4) Before our lecture on Wednesday 1/18/2012, please register your iclicker at http://www.iclicker.com/. Then select "Register Your Clicker". Enter your first name, last name, student ID (such as A00012345, starting with the letter "A"), and the clicker ID from the back of your device. Use the full version of your name as it appears on the official transcript. Do not use any abbreviations such as Mike, Alex, Chris, etc. if your full first name is Michael, Alexander, or Christine. Also do not use your middle name instead of your first name. If there is a typo in your student ID and I cannot identify you by full name, I cannot award iclicker points at the end of the semester. Usually, several students with the same last name and similar first names can be found in Stat 2000 each semester.

  Each week, several students will be given the opportunity to present their answers to some of the RPs to the other students in a recitation session. Depending on the length, difficulty, and correctness of your presentation, you may be awarded up to 3 bonus points each week. We will try to give as many students as possible an opportunity to present their answers. However, there is no guarantee that in a particular week you will be among the students who can present their answers.
