i took him for exper design and quantative methods... the class is pretty hard, and the TA's kinda sucked,if you wanted to understand the labs you had to go to them for extra help..also the book sucks so you have to go to class. coreys nice though.

I found Corey's lectures to be boring, but not very hard to follow. His tests come mostly from lectures & if there are questions that are going to come from the book he tells you exactly where to look. He has 4 tests & drops the lowest & the curve is huge! you can go from a C to an A. EC available

Have to go to class for the tests, the took is almost useless

I thought Dr. Corey was great. He really knows his stuff, but you HAVE to come to class and not zone out for a second or you'll miss vital information. He's really nice and doesn't mind repeating or explaining ideas until you understand. DON'T BUY THE BOOK!! Find someone who has it and copy all the tables from the Appendix. Good luck!!

My guess is the people giving bad ratings are 1 of 3 things 1) people who never go to class (you'll be screwed if you don't) 2) not auditory learners (all the course material comes from his lectures) and 3) not math people. Go to class, don't buy the book, right down everything he says/ writes on the board. Honestly, I didn't think it was hard.

He is very intelligent and a good instructor, but in order to do well, you must go to class and take good notes. If you do this, and go to his office hours when you don't understand something, it will be very easy to do well in his class.

This class is NOT as bad as people make it out to be and Corey is actually a great professor. If you study hard, attend all the lectures and take good notes, then you should have no problem. Also, he lets you keep the exams after the test.. so it is helpful if you can get a hold of someone's old exams to help you prep for the tests.

This class is difficult, but you don't have a choice. Dr. Corey is extremely helpful and willing to answer all questions. Write down every word he says! Tests have words and you have to write out the definition word-for-word.

Don't bother buying the text, you won't open it once. You HAVE to go to class, because tests are totally based on lecture. It's easy material, he just isn't always clear about what you have to know. Make friends in class and form study groups. His exams are all open ended questions but the final was multiple choice. Requires a lot of memorizing.

Dr. corey teaches his class straight from his head and you dont need the book if you go to class. During lecture, he does a lot of reexplaining things and examples, but if you understand statistics, then this class should be no problem and, since attendance isnt required, a no show for you

I think Corey is actually a really good professor. You really have to go to class and actually pay attention because he doesn't follow the book sequentially and says everything you need to know. The book can be helpful when you study for test, though. His tests are hard, but they're based on a curve, so it's not difficult to do well.

He's a great teacher, he just has a boring class. But, he makes it seem like he actually wants to teach, a big difference from most of the other required class teachers. I really liked him. You just have to pay attention in class and take notes and you'll do fine

He is a really great teacher. He repeats himself a lot so if you didn't understand the first time, you will the second time. The subject isn't that interesting, but he makes it as interesting as possible with real life examples. Using the book is optional because you are tested on what he says in class so take good notes.

I don't get why everyone is so afraid of this class or why anyone would have so many negative things to say about Dr. Corey. Sure, the material is super boring, but he does his best. Dr. Corey is an extremely fair professor and gives extra credit. Come to class (which I guess is terrible at 8 AM) and study your notes, you will get an A or B.

Dave is a great guy and tries his best, but univariate is naturally a boring subject and can be really tough if you're not a math person.

I've heard this class would be difficult so I put a lot of effort in. Overall I can't complain - he is pretty straight forward and TAs are very helpful. Don't buy the textbook, you won't need it.

Corey is a nice enough guy and the univariate lectures aren't terrible (ALWAYS at 8am tho), but the part of this class that gets you are the labs. They're just brutal 1 or 2 hour long videos of Corey talking and doing calculations in spreadsheets, and you just watch and copy. It's a challenging way to learn, I always found myself dreading them.

Overall this was the best math class I took so far at Tulane. He cares about his students and actually tries during the lectures to make sure the students are understanding. He even makes these labs for you to watch when doing your homework. Would I take this class again? No. But he definitely made it better than it could've been.

Professor Corey is very articulate & makes the concepts understandable if you go to class & pay attention. All the notes are uploaded & labs reinforce what you learn in lecture. This class is not hard & he is fair (curves), but you have to get up for the 8 AM & memorize what he tells you to memorize to do well. These other reviews are dramatic.

Professor Corey gets a bad rep, but I think that has to do more with the fact that this class is an 8AM rather than his teaching style. He is very clear and good at explaining concepts, and each class he reviews previous material before moving on. Takes plenty of time to answer all questions. Tests are hard but given a big curve. I liked him a lot!

Really surprised by all the negative feedback here, Dr. Corey is fantastic. Univariate, while dull, was an easy enough class as long as you attended and paid attention in class. Tests are VERY similar to the practice tests. Labs are long, but if you do well on them they will boost your grade.

Different kind of stats. Be prepared to memorize definitions, conclusions etc. Posts all his notes, a semester long study guide, and a video walkthrough to follow for labs. Ask a friend for old tests. Final is almost all MC (easier or harder depending on person; i did not do well).

Take both Univariate I and II with Professor Corey. One of the best professors in Tulane. He is very knowledgable in statistics. And his lectures are very clear and organized. Also, he is very helpful and accessible outside class. Univariate II can let you know how to practically use statistical concepts.

The fact that Univariate is only offered at 8am is terrible. The class itself is hard and involves a lot of work, but it's not Dr. Corey's fault. He's a fantastic teacher and also a really cool guy in general. I think most people on here are rating the class and not the person.

Good professor and has the class set up really well. If you take good notes on the videos you will be fine since all quizzes are open-note. Labs are a pain but super easy if you just follow the videos. Do the SONA extra credit

I took Professor Corey's online Univariate Statistics I course this summer. He was organized and was willing to help us with any questions we had. He allowed for one on one time and always helped us with labs. Watch his videos and listen in lectures, and it will be fine. The class itself is a little harder, but he really helps. He is kind & funny.

Univariate sucks but Dr Corey really isn't that bad. I feel like those who say its hard just don't watch the lecture videos before class, which is something he literally emphasizes in the syllabus. Labs are long and annoying, but easy if you can stay focused. Quizzes are hard sometimes, but the labs make up for them and bring up your grade.

Prof. Corey uses a flipped classroom, which is time consuming, but if you are willing to put the work in, you can get a good grade in the class. A lot of the stuff is just participation or easy to get full credit on, but there are weekly in-class quizzes which sucks because it's an 8AM. Psych majors have to take this with him, but he's pretty nice

Dr. Corey is very funny and lectures well for what can be a dull subject. I will say I'm not the biggest fan of the flipped model. You are supposed to watch prerecorded videos and take notes before attending the Zoom meetings. The labs are TEDIOUS, make sure you know some excel shortcuts and get a mouse for your laptop to make navigation quicker.

Fall 2025 was the first time this course was in person. Dr. Corey is funny and cares about his students. If you watch the module videos, you do not really need to go to class, but it definitely helps the material make more sense. He is available for office hours. Tests are not bad if you go to class and study. Keep up with the module videos.

We had 3 midterms + final. Everyone who is getting bad grades never studies or goes to office hours. He's super nice and will tell you exactly what to study for so don't be scared to ask him questions! Also I haven't been to class in months but it doesn't matter because everything you need to know is in the videos. Take time to do the labs well

This class is more vocab than math, he posts all the lectures online in short videos, so just watch them before the test and you will do amazing. He also has an amazing curve and offers extra credit. He posts step-by-step tutorials for the labs, and as long as you submit before your lab time starts, you don't have to show up.

David Corey is an amazing professor - he is so kind and genuinely wants his students to do well. Univariate is an insanely hard class but if you put in significant effort you can do well. Make sure you watch all of his videos for the modules because that helped me more than the in class lectures.

As someone who was very nervous about this class, it really wasn't that bad. Professor Corey is a great person who is very accessible and helpful ESPECIALLY if you go to in person class. He is awesome at answering questions and clarifying. Lectures were helpful. Very test heavy. He provides study guides that are very helpful.
