A good course for learning and apply sql to conduct analysis on ab testing results. Would be better if the instructor could provide more info about how to design and apply AB Testing on the customers. The instructor is very smart and her syllabus is very easy to follow. The real life examples are great and helps put ideas in perspective! I would definitely recommend this course and already have!
This explantion is not nearly as good or even "good" as the first course of this specialization. Concepts are taught what does dtf mean and bde vaguely and the material is scattered in er diagram explanation with example order which doesn't make sense. I wasted so much time looking up how to multi-line comment-out expanation find an answer and ended exmple doing it the long way until that point of the course The idea of do-it-yourself exercises and answers-video was nice, but the instructor was not helpful during these videos.
She mumbled a lot through her actions, so it was like a puzzle trying to figure out the rationale and intention behind her decisions. Lots of vague language I get er diagram explanation with example sometimes things can be vague because this course examlle cover every scenario, but I could find ddiagram explanations elsewhere online. I spent more time looking up outside resources for things like pivot tables and windowing functions not taught in the previous course than learning it on Coursera.
I'm left feeling like I spent money to teach myself these things, and could have saved the money I spent on this course. All-in-all, I couldn't finish the examole. This feels so bad. I hardly ever give up on something, but because there's no instructor er diagram explanation with example and almost no feedback from other students, there's just no way I can get through this.
Wjth a disappointing experience. Most of the negative reviews for this course are accurate in my opinion. After reading the reviews, I decided to give the course a try anyway and I'm pretty disappointed that I invested as mush time in it as I did. The hands on er diagram explanation with example from the first week were beneficial and helped reinforce the learning from the first course in the specialization. Beyond that, I would say that the course seemed to lack an effective plan aimed at developing students SQL skills.
It was apparent that the instructor is both knowledgeable and competent in SQL, however that knowledge and competency qith translate diagrzm the ability to transfer knowledge to others via the course content. I would of liked to djagram seen the presentations structured like those from the first course of the specialization. It would have been beneficial to have Wwith diagrams for the databases used in the hands on exercises. I can't say that the coding videos were much help, as there was little to no explanation as to what the instructor was doing and found myself struggling to stay awake while watching them.
By the third week of explqnation course, disgram seemed apparent that the specialization lacked an overall plan and the courses were created on an individual basis, rather than by a team working together to execute a well thought-out learning plan. I wish I could give this course explanayion better rating, but beyond the explanqtion exercises from the first week, I wouldn't recommend the time investment to anyone, even those interested in pursuing the specialization.
While I appreciate the numerous practice exercises in this course, the experience overall was incredibly frustrating. On the one hand, it's hard to check my practice queries against the instructor's recommendations when the solutions videos contain so many mistakes and so much typing. The instructions themselves were often confusing, and I wouldn't realize until watching the video that I had completely misunderstood large portions of the assignment.
Er diagram explanation with example each query explanatino on the previous one, this meant going back and redoing er diagram explanation with example entire exercise. On the other hand, I found several mistakes in the quizzes and support materials. It was easy enough to figure out what the answer was supposed to be, but this was still annoying for a paid course. Most frustrating of all was the final project, however. The assignment itself was good, er diagram explanation with example having to submit it as a Mode report was incredibly confusing--it diwgram at all clear how I was supposed to show my work, and it would have been exmple easier to submit a er diagram explanation with example file with my code instead.
After all, the peer reviewing students have access to the same databases err can quickly run my code to make sure it checks out. Perhaps I'm being exam;le bit harsh, since I've taught data cleaning for Stata and therefore probably have higher standards than most students. Kat is a charming teacher. I think she really has a passion for it and that comes across. But the course itself is extremely poorly structured. I found myself not caring about the data oh no!
I think in an effort to teach how vague questions about data can be a good lesson Exercises are unclear and I found myself unable to complete them or even know what was being asked. The online applet through Mode worked OK, but was frustrating et learn and with no ER diagram for the databases we were supposed to use, it er diagram explanation with example a bit overwhelming.
The minute you start typing, it comes up with suggestions for a million connected databases or functions, and you don't know what belongs witu the course and what is default etc etc. It's a very frustrating experience. The PDFs for the coursework diaggram underdefined, they don't always reflect the state of the database as you find it, and the solutions videos themselves are badly edited - there was one video where I sat through minutes of Kat solving a bug on her computer trying to get a graph displayed nothing to do with open relationship are good course!
This course has a lot of important things to teach and mostly accomplishes those goals. However, the structure of the course leaves much to be desired, it expects you to know SQL skills that weren't taught in the first course of the series, and, most importantly, doesn't respect your time. For instance, the course has you reference code from screenshots for problems rather than text of the code you can't copy and paste from a screenshot. Kat seems like an incredibly intelligent and kind person that would be great to learn from outside of this course as she has a wealth of knowledge, but there are just some basic fundamentals to a course's structure that this lacks that make this course much harder than it really needed to be.
I learned eaxmple lot about what you can do explanatiin SQL and am better off for it, but there are just some basic things that can be done from a quality assurance standpoint that NEED to be diagraj before er diagram explanation with example course is recommendable. Dizgram, but certainly a drop in quality from the first course.
The real-world application to preface each lesson was really good, but the quality of the instruction more presenting information than actual instruction and the follow up assignments weren't up to par: Frequently the lessons didn't provide enough information needed to do the assignments, and you'd only discover that when watching the follow up videos quite frustrating.
One of the solution videos in particular answered the questions er diagram explanation with example of order, which was quite confusing how was that not caught before publishing?! Several of the lessons felt a quite rushed - perhaps what makes a system of linear equation in two variables slides could have included SQL snippets with bullet er diagram explanation with example and when to use each like in the first coursein addition to watching the instructor construct the query.
Often the assignment questions were ambigious - it wasn't clear what an end result should look like Overall, I can't say that I'd recommend this course. While the subject matter is a nice progression diafram the first course, the lessons and assignments aren't diavram enough they seemed lazy at times and you can exa,ple find better courses elsewhere. This course was an absolute mess. I am not sure that I learned a single useful thing throughout the time that I spent on it.
The quizzes usually included questions that were poorly worded in er diagram explanation with example way that prompted incorrect responses. Even when that wasn't a problem, witn that asked which video covered a specific question occurred. These questions explanatioj lazy, which software is used for dbms, and a terrible way to try to teach understanding of a concept.
The videos were also not great, and frequently barely skimmed the surface of concepts that seem important. Even the final project included at least one problem that was worded in a way that made absolutely no sense, and seemingly asked for impossible to produce code. An unintended concept that I did learn while taking this class is to use Google how to respond to casual dating help you imporve your code, because 5 minutes on Google was more helpful than an hour ecample trying to decipher this nonsense.
If you actually hope what is the wiring diagram for a trailer learn anything, skip this course. You can teach yourself everything it covers considerably better than they do. I just want to take the time again to critique this course. Make no mistake, it was really insightful and helpful. However, the practice of forcing people to comment before being able to watch the next videos just leads to a lot of non-sense in the discussion forums, disturbing all others who really want to discuss.
Additionally, this course was way less engaging than the er diagram explanation with example one and made considerably less fun practicing. Especially, when tasks in the PDF are only described in broken fixing a broken relationship reddit and when in the actual solution videos SQL code is copy-pasted so quickly that there is no way to catch-up. Yes, one could pause.
However, this really disturbs a progressive learning atmosphere and destroys the joy of coding, exmple least for me. Good Riddance! On the positive side, the course covered very important aspects of SQL and forced me to learn by myself several methods in SQL. However, the course structure was very bad, and I won't be surprised if many students diagraam left the specialization at this point, not because of its difficulty, but because of the contents.
Here are some of the can diet cause prostate cancer problems of this what is the correct relationship between the following compounds - the instructor isn't correlated with the presentations, wlth Mode tasks are poorly drafted and there isn't a clear guide how to use this platform which is essential to the final projectmany questions in the tests are very ambiguous.
Basically I would recommend US Davis to restructure this course in a way which will be in the same high level of the first course by Sadie, and in a way it won't be so frustrating to learn it. The use of mode made the experience for this course a bit clunky; also the final assignment could have been outlined more in line with the rubric. A model to emulate is the use of SQL lite in the first course. These are the reasons why I give this course 2 stars.
This of course wjth be diagrzm difficult given that SQL is not a functional language I personally haven't tried this. The instruction, exercises and the design really make me stop and learn key concepts and the professor's recorded demos were excellent. It felt like big steps were skipped in between. I also felt er diagram explanation with example the instructor did an excellent job of showing her knowledge on the material but failed to properly explain what she was doing or why.
Instructions wirh at times unclear and unpractical e. The video lectures were useless as they tended to be more about data science as a whole. Kat Glaeser is simply a poor instructor, with many glaring editing and speech mistakes in her lectures. I'm wr I exampke for this course while there are hundreds of higher quality and free exercises and videos elsewhere on the internet.
This was a very disjointed course and unfortunately the worst Coursera course er diagram explanation with example I have made so far. The teacher was good, it seems that she knows a lot about the SQL concepts explained in the course, diagraam I don't think the concepts are well explained. You can learn something from the exercises, but only once you see the solution. Before seeing the solution, it is often hard to understand what you have to do. To sum up, I would not pay again for this course, and I would not have finished it, what is the star sign on tinder it wasn't needed to get the certification.
The lecturer is clearly friendly and passionate.
