Statistics 21 (Prof. Purves) Study Group ---Last Updated Dec 12/8 10pm---
SG Leader: Lawrence Wang
SG Time/place: 113 Chavez, TuTh 1-2
My drop-in hours: MW 10-11, TuTh 10-12, 2-4 (At SLC Atrium, Math/Stat tutoring is 10-4 M-Th)
My email: l_wang at berkeley
Notes: I'm providing these answers to you guys as a convenience: Remember that when you are practicing, the process of solving a problem is more important than getting a problem right, and remember that it's possible to get an answer right but have wrong reasoning.
Also, my email is for asking questions about study group issues (missing sessions and need worksheets, questions on procedures and stuff, etc.). It's too inefficient for me to tutor you guys over email, among other reasons. If you have stat 21 questions, please come to drop-in hours (if you have questions about what I did in group, preferably come during my hours)
NOTE: IF you think there are mistakes in my answers, please email me. (Or just note that it's possible that there are mistakes)
