Juana Sanchez is a really good professor, you just have to be polite and make her feel that you are involved in the class. Her exams are pretty long but the questions are not that hard. She provides very clear and concise study notes and the homework are helpful for the midterms and final. Some people complain that she gives them anxiety but don't take her too seriously, she is not mean, she just wants everyone to study the minimum required. She is actually pretty helpful in office hours, so don't hesitate to go and see her to ask questions about the class or homework. The material of the class is very interesting and really not that difficult overall.

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.

TLDR: Take another prof. You learn the same materials and don't have to deal with her headache.

I've had Sanchez for 2 quarters in a row, and I gotta say... avoid taking a class with her at any cost. After doing pretty badly in her 100A, I worked my butt off to try and make it up, but it didn't really help much.

In a previous review I wrote for her 100A class, she fails to explain ANYTHING well. And honestly, her 100A and 100B are completely separate. The terms she uses for population and samples are basically the same, so you never actually know what she's asking for(EG: estimated sample variance vs. sigma hat squared vs. S^2). For those who take this class without taking Stats 10 or forgot most of their AP stats, she briskly goes through the material, and those without this background often don't really understand why we run certain tests and under what assumptions(so I definitely recommend taking Stats 10, which I took concurrently for GE credit lol).

For the final, literally 5 of the 30 MC questions she gave us either didn't have the right answer as an option, so she either said "choose _" or "choose what is CLOSEST to your answer"... like... what? EG the options are 12, 17, 19, 23 and you get 6...

Before the midterm, the point dist was: 3 quizzes of 5% each, 35% midterm, 35% final, 5% participation(which are either attendance or last minute quizzes she crams in), and 10% homework, 2 of which are dropped. But because midterm scores were so horrendous(median was like 70% or 21/20, skewed left with some 30s%), she made the final easier imo and made it worth more. There is a curve at the end depending on percentile, but whoever hasn't dropped after the midterm honestly is either an international student who already learned it, or a mathematician/CS legend who knows it, so you end up just struggling. Just take it with anyone else - you learn the same material but actually have a better prof.

Avoid Sanchez at all costs. I’ve had her for both 100A and 100B and she’s really just the worst. She’s a terrible teacher, prepare to teach the course yourself, which you’ll have a hard time doing considering there’s no textbook.

The midterm, quizzes, and final are all super challenging. The homework’s are also very difficult, I would constantly be getting points docked on those

I see there haven't been any reviews in a while, so I decided to write one.

If you're reading this and feeling hopeful, don't worry, she's still awful in 2019. And even better: she was the only professor teaching 100B this quarter!

I was lucky to have taken Math 170A instead of Stats 100A. Be ready for non-rigorous proofs, unclear assumptions, and answering extremely trivial color card questions while she skips over all of the interesting concepts by flying through numerical examples. Not a great lecturer.

I've never met a disorganized person with OCD before Juana. She will refuse your homework if it isn't in the right format, while changing what the expected format is every week. Is it a problem from the lecture notes? An online quiz? Do I have to print out HER specific sheet, then find a way to scan my assignment and upload a PDF? Is it due in lecture or Saturday at noon? It's always a toss up.

She will haphazardly change her slide formats, and switch between lecture and story time, but then chew you out like your mom if you talk at all in class. And heaven forbid if you bring a graphing calculator to the quiz.

The textbook was free at least, but it honestly sucked. My recommendation: Khan Academy and jbstatistics on Youtube.

She is a little bit worse than average but not too bad, because her lecture speed is too slow. And her office hour is kinda special because she only allows one student on time to enter her office to ask question. For the class, we have 3 quizzes, one midterm and one final which are 20%,25% and 35% respectively. And there is 5% attendance, and the rest are hw. As a stats major, I don't think she is not as bad as other students claimed of you know math professor Song.Finally, her tests are pretty fair. When she said the quiz or whatever is based on the lecture, she really means it.

teaches at a middle school level( really,,,,,gives attendance points, picks on students to answer questions etc.) . Her goal is to get as many people to come to class as possible, while she doesn't care about the students' learning. If youre used to the math professors at UCLA, just know that she's nothing like them,,,,,,she's a proof of the Statistics department being much lower ranked then the math department. Take her only if you miss your junior high teachers...

Ironically, I believed all the miserable stuff that people wrote about this professor (about how she is hard, can't speak right)......and I too thought this was going to be the worst stats class ever (in other words, defeating myself before ever entering the class). So I went to the class with extreme caution. As time went on and I continued to go to class with only (maybe 15 ppl in the class while other stats teachers each had 80 students) I learned an extreme amount of useful information. Not only was she helpful during office hours (which I suggest you ALWAYS go to for not only about hw questions but also general confusions about the material). Here lectures were perfect, no accents in language, and I think she lectured cohesively. I have to admit the HW was a bit tough but Office Hours is a perfect place to clear any confusions. The midterm was a bit hard but it was open book(s), and notes, and it was 3 hours long (yes, like a final time limit). The FINAL however was a damn TAKE HOME FINAL and we had 3 full days to work on it. And it would replace the midterm score, and count for 70% of the class grade. The class break-down was 10% participation- JUST GO TO CLASS, believe me she knows very well who goes to class and who doesn't- to the point where she knows everyones name by the end of 2nd or 3rd week. And 20% HOMEWORK. and obviously, 70% for the final. So I don't know what all these people complain about. This professor is ALWAYS and I am mean ALWAYS there to help!!! TRUST ME. I aced the class.

Sanchez is not an effective professor. She makes way too much mistakes in class, she is often confused and ends up confusing most of the class. We had to go to the TA to understand a lot of the material. Her office hours do not help either because she often refers you to read the handout which is also often confusing.

Just avoid Sanchez if you can.
