The thing I love about Professor Sanchez is that she is the best at making concepts easy to understand:

(directly from 02/20/2015 lecture)

SANCHEZ: So, would you say that the people that are in the ‘college or higher’ group are independent of the people that are in the ‘high school or lower’ group? Do you think they are independent? Yes or no? Be, be courageous.

STUDENT: (shy) Yes.

SANCHEZ: Yes, yes. That’s it. Yeah. No, they are not. They are independent, right? No. They are not independent. Right? What did you say. Yes or no. No. You said yes they are independent, or yes they are not?

STUDENT: Independent.

SANCHEZ: Yes. They are independent. No. Yes. They are not independent, okay? They are not independent. I mean, sorry. Yes. They are independent.

Fuck this class.

Looking for an easy A? Then take this class. Professor Sanchez's lectures are absolutely useless, but luckily I had taken Math 3c the quarter before so I knew a lot of the material going in. She's not the best professor, but she makes things really easy for you. ONLINE midterm and final. Let me repeat that: THE MIDTERM AND FINAL ARE ONLINE. Open book, open note. Sure, the weekly online homework and quizzes are annoying and time-consuming, but they're not difficult at all. Pearson is actually really helpful and you can learn the material by using that website rather than attending lecture. This class also doesn't use a clicker; she takes attendance by randomly calling out names to answer questions. She usually only calls out 9-10 names AT MOST, so if you have to skip lecture, don't get too worked up about it. I would REALLY recommend this stats class over the others, because you can pretty much bullshit right through it, while the others will probably require you to actually LEARN the material.

Professor Sanchez is extremely concerned about her students and her office hours are extremely flexible. Her class is not easy and there's plenty of work involved but the material is very straight forward and help is always there when you need it. The tests are not very difficult and she finds ways to help your grade (extra credit, etc). If you show up to all the lectures, labs, and discussions this class should be a cakewalk. Overall, extremely caring, energetic, and fair professor. Highly recommended!

If you don't like going to class which I don't this class is lame, because if you don't make it you loose stupid participation points from lectures and its idiotic. I highly suggest not taking this professor if you don't go to class, her lectures are pointless and I have to go for the participation, which I never get because its always on some random day I don't go. Overall easy class, just do all the tedious requirements to do well, doesn't test ability, it tests stamina to not quit on pointless tasks, which is harder in my opinion than ability.

Horrible horrible class. I had crippling anxiety and walking into this class tipped me over the edge. Her homeworks are overload and are carelessly created (full of mistakes and unclear directions) -- however because of this she is lenient on the grading. The group "quizzes" she assigned took an entire weekends worth of time and she ended up handing out A's to everyone that completed it.

Contradicts herself a lot during lecture and has an attitude. For example in the beg of the quarter she would get mad at people who would just listen to her instead of taking notes, and she said "What are you guys doing? You guys should be typing and not just listening... you need to turn this in. Please get busy". Later on during the quarter when we are typing what she's typing, she yells "Can you guys please stop typing. Just listen.".

Always lets us out late -- this is a problem because she opens up submission forms for in class participation activities when class is supposed to be dismissed and she talks about the weekends homework assignment after the class is supposed to end.... always end up being 5 minutes late to my next class.

Last thing: Grading is very inconsistent. First 3 or so quizzes were grader rather rigorously. Average was a C, but towards the end the quiz averages were 90-95. Not sure whether this class was curved or raw scored, but if it was curved, this method makes it impossible to beat the class average and better your grade especially if you got off to a poor start.

Tips for prof: End class on time and make more manageable homeworks. Also keep grading consistent please.

That's right kiddies - your thousands of dollars in tuition help pay and endorse incompetent, useless, and indecent professors like Juana Sanchez! There were so many issues in this course that I can only imagine where to begin.

To begin, she did not properly answer any questions asked in class or office hours AND got defensive whenever you tried to assert that she is not answering the question you are asking. Well that helps. She is also rather rude when addressing anyone....I guess incompetency and indecency go hand in hand.

Oh btw, need some help with homework? Sure! Get in line outside her office - she only serves ONE PERSON AT A TIME EVEN IF MULTIPLE STUDENTS HAVE THE EXACT SAME QUESTION!! Want a regrade? Fill out some retarded form and give it to her - you may or may not get an answer. Any other query? Shoot her an email and set up an appointment. Oh wait...she does not even read emails. Pity.

Need an effective way to waste class time? Sanchez has got you covered. She will make random students go up to the black board and literally - word for word - write something that is already in the notes she hands out at the beginning of class. I'm rather proud - a friend of mine and I called her out for this ridiculous practice and refused to do it. It was glorious.

Homework? You had better follow her specifications or, as a nice evaluation below puts it, points off for every little minor fucking detail...like your assignment # not being in the correct place or a badly stapled paper. I also should mention that the typos are strong with this one. Difficulty wise it is not too bad.

Her exam administration is undoubtedly the best part though. 50 minute exam? More like 25 because she takes 15 minutes to take roll call (YES ROLL CALL !! WHICH PROFESSOR TAKES ROLL CALL DURING EXAM TIME?!) and will end the exam 10 minutes early with no warning. Final exam? 35 minutes to take roll call and ended 10 minutes early with no warning. Seating is also retarded. On the first exam we had to sit in a very tight formation in a classroom where a plethora of seats were available....just so that she could walk around the exam room and check your ID 4 times (YES 4 TIMES!!). Next exam and final was the usual one space in between. But wait....you could not use the desk next to you to balance your cheat sheets, test, scantron, calculator, pencils, eraser, exam, and a sheet she gave containing some of the typos on the exam. Can't use that desk or even the floor because it's "cheating". Yup it's going to be a balancing act on one desk and your knee ladies and gentlemen.

The exams themselves? I would recommend going through all practice exams and homeworks to memorize the answers to every multiple choice question. My friend and I managed to answer 11 out of 43 MC questions on the final in 45 seconds. Some of these questions required an immense amount of calculation that could have easily eaten away almost 10 minutes or more if there was an error in punching in numbers at any point. I also should mention that some questions have identical answer choices (A and C could literally be the exact same answer) while some questions may not even HAVE a correct answer (not mentioned on the error sheet she gave us). Our final, which was initially out of 51 points, got reduced to 47. How ironic....I stumbled across 4 questions that did not seem to have a correct answer while taking the exam myself...hmm....You can probably imagine how long students could waste on these questions trying to figure out why their answer is not there.

Overall, this professor intentionally and unintentionally through ridiculous policies and sheer incompetency makes this class more tedious than it needs to be. I have no idea why she still has a job. She does not deserve to teach at a reputable university...or at any university really. And that, kiddies, wraps up this eval.

I've taken much harder courses, but this class was definitely a memorable experience.

Example: we had these wackass color cards that we had to raise up to answer a question. One time, when she didn't see enough cards up, she took roll call (by hand of course LOL). ?????????????I thought it was pretty funny

Juana also has... strange mannerisms. There was a loudass chick talking while she was lecturing, which was really annoying. But how did Sanchez deal with it? She got pissed and yelled "SHUT UP!!!" And then she got red in the face and seemed kind of embarrassed afterwards. I mean, she was right, but our class still went googly eyed while I sat there laughing my ass off.

Still though, I liked the material of the class and she did teach it well. As a lecturer she was fine; the stuff she taught made sense to me, and wasn't confusing or difficult in any way. I found the review below complaining about how she changes between S^2 and sigma^2 pretty funny, since that guy clearly didn't bother learning the difference between those terms at all.

Basically, it's hard to evaluate her when everyone in the class was just being so stupid in general. She definitely yelled at people who deserved it, though it is somewhat uncomfortable when it happens. But that other review about the person with crippling anxiety who decided to take Sanchez in 2017? lmaooooooo kid yourself these people are exactly what I'm talking about

Some actual advice to do well in her class:

Study the lecture notes she prints out, and nothing more. On multiple questions in exams she just pulled examples straight from her notes. I studied less than 6 hours per midterm using this method only.

Her tests are long, but each question itself is easy. When she does her trollass routine where she checks your phone, your backpack, your ID, your cheat sheet, your birth certificate, blah blah blah, don't get frustrated or upset. Just keep your head down and work. Don't even acknowledge it. Get the easy test done while your peers angrily bitch about her policies and write meme reviews on Bruinwalk about how "impossible" her class is.

I've had her multiple times for multiple courses (100C, 102A). I don't understand why they still let her teach.
She has plenty of positive reviews but I think they're largely because the people writing them are not stats majors. I can see that she would be a good professor if you'd like things really simple or generally aren't mathematically inclined. But that being said, if you would like your professors to speak to your level, be logical, make sense, or understand what they're teaching (especially at the undergraduate level), Juana is not for you. She's nice but she's infuriating. Her questions on homework and in tests don't make sense. Her notes aren't proofread (such as, she didn't run her code before class for 102A, so wasted a lot of time during class troubleshooting her R code).
She may be great for Stats 10 (I wouldn't know, I didn't have her), but seriously, for upper division, wait a year and see if someone else is teaching it.

First off LOL the picture posted on here is funny,

I wouldn't take her if i could, almost every other Stats professor at ucla is better, not to say she's bad, the rest of the STATS prof are really good

if you do take her, she might refer to a "book" a lot but dont bother reading it, anything she will test you on is based off her lecture notes

memorize all her examples in class or on the lecture notes because her tests have problems from lecture and homework... almost all the problems on the tests you would have seen before

Best of luck
