BUY A GRAPHING CALCULATOR. As long as you go to your 2 section's a week, and have a calculator you will pass. Do the homework before the quiz and you will likely get an A. Quizzes are based on the hw problems. The lab section is basically show up get 100%. You can miss 1 quiz and 1 lab. Grading is curved to where an 85% is an A- and 70% is a B-.

Chavez was a great professor and very easygoing. If you don't attendpay attention in lecture (which was not required to attend), you might find the class pretty difficult. There are weekly quizzes (easy if you do HW), and 2 midterms (no final), they were again, easy, if you could solve practice exams. Very fair tests & grades! DON'T BUY TEXTBOOK.

Easy-going, friendly, and helpful professor who is very approachable for questions outside of class. There were weekly quizzes and 2 midterms (no final), but they were easy if you did the homework and looked over the slides. There were annoying lab sections every week, but they were easy points if you showed up. His tests and grading are fair

He gives out quizzes weekly but they are fairly easy if you do the homework. His lectures are helpful and he requires students to know only the basic concepts. He gives out two midterms and no final. If you can solve the practice midterms, then you can definitely do well on midterms. Nice and easygoing professor!

He is clear and his slides are extremely helpful. He posts all of them on GauchoSpace, so you technically do not have to go to lecture. But I'd advise you to go because he teaches how to use the TI8384 calculator. Go to Lab sections which are easy marks. Quizzes are ok, yet exams are tough. DO NOT BUY BOOK. BUY CALCULATOR.

I found this class challenging. First off, i'm the type of person who understands material when the professor writes on the board, but Chavez simply reads off his slides 80% of the time. He has practice problems on the slides, and he'll just read the problem and the answer with no explanation. Go to his office hours, they are MORE helpful that Lec.

He's clear, friendly, and wants you to succeed in the class. The tests are exactly what you cover in class and on the homeworks (there is no homework grade but you should still do them since the quizzes and tests are similar). Be sure to know the concepts well because the final is brutal. The midterm isn't bad though.

Really hard class but Chavez is excellent at explaining things and he is really helpful when you ask questions.

There seems to be the same person giving neg ratings which i feel is undeserving. Hes easily one of the best teachers that ive ever taken at ucsb. Hes very easy going and flexible. Hes down to earth and will be there to help. He gave me the pdf of the book. He does make some minor mistakes 'my bad' but its funny to me rather than an indictment

The class and the material is pretty hard, he is also a bit of a harsh grader (midterm/final avg are usually around 50%), except he curves people's grades very nicely so the low test averages don't matter that much. I did spend A LOT of time to get the A- tho..

Chavez is by far the most helpful professor in stats. He makes himself available to help out students. He gives different solutions to a specific problem as to help his students out more if one procedure doesn't make sense.

Chavez is good teacher. He makes himself available all the time to help students understand the material. The course is incredibly challenging and the material is insane, but go to lecture and office hours and Chavez will do his best to explain it. Very nice guy and seems enthusiastic about the material. Work hard and study hard and you'll do fine
