Stats 221 has been dumbed down, generalized, and standardized, so it probably doesn't matter who you take it from (in fact if you are confident with math, just take it online) but Dr. Christensen does an excellent job of explaining the material and makes it entertaining.

This class is difficult and fast-paced. If you took stats in high school, it'll probably be easier for you. I didn't and I had to work hard to do well. Study super hard for the tests or your grade will suffer. I barely got a B+ thanks to the curve. Christensen is a quirky but knowledgable person and a good professor. Would recommend for STAT 121.

Great guy! This class can be very overwhelming if you get behind so be sure to attend lecture. He is very caring and keeps lecture interesting. I relied very heavily on the TA labs, they can help you work through homework and personal questions on a one on one level. The labs are what saved my grades and all the TA's are great, use them!

This Professor is awesome! I actually had him for Stat 121 as well In the weekly homework assignment, there was a lot to do, with so many details! I felt lost at the beginning, just because I hadn't used R before. But it was WAY worth it. Take 230 from him! He has a good way of explaining tough concepts in simple layman's terms. Use the TAs!

Teaching a lecture with 100+ students is no easy task, but Dr. Christensen was entertaining, moved at a great pace, and always allowed for questions. Statistics can be tricky sometimes, but he taught very simply. Note: there is a TA lab in the West View Building that a lot of people don't know about where you can get help! Use your resources.
