學生對 加州大学戴维斯分校 提供的 Data Wrangling, Analysis and AB Testing with SQL 的評價和反饋

Pretty informative course!

Sometimes the descriptions of the practice exercises seem a bit fuzzy, but as you go with the course it gets easier to understand how to interpret the requirements. Very helpful solution videos!

The course is not very well structure, I understand that this subject is not the easiest one to teach, but one thing that could help is to give a structured representation of the database with all the keys that are in it. you have to almost guess what is in it.

The videos should be more carefully planned, the solution videos are a little messy and some steps are not explain

A very thorough overview of SQL and how to best structure data tables and metrics for AB testing. I appreciate the high quality content of the UC Davis courses!

Course was ok overall. I learned the basics and the SQL was good. I learned a lot about the basics of SQL through the course. However, the video could have been better edited and the prompts/questions (especially in the final project) were difficult to understand.

I'll give it a 5 mostly because this is one of the few in-depth SQL courses on the site, plus it actually goes beyond Joins and all that other pre-advanced stuff. I actually learnt new methods such as using windowing functions and using AB Testing. It could be better yes but we need more practical courses like this one.

Great course!! I have learned a lot about how to evaluate the quality of the data received, how to problem solve with SQL when asked ambiguous business requirements, tips to do multiple selection editing in text editor (that was a great discovery!), metrics and AB testing. Highly recommended!

The information in this course is very great as well as the practical part of the course. The instructor was very great and knowledgeable. Thus, I recommend this program to anyone who is interested in learning SQL queries.

The assignments are pretty difficult, and I think this course suits those who have advanced SQL skills and wanna use SQL to solve higher level problems. The lecturer are pretty interesting, and I enjoy that.

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

It is pretty useful course to understand how to prepare data for AB Testing in real database environment. you should know SQL intermediate leve before starting this course.

Gracias por impartir conocimientos online y darnos la posibilidad, a quienes trabajamos seguir perfeccionándonos, organizando los tiempos personles

Overall great course, really get's you into data wrangling and exploring data in SQL with in almost real life situations.

Bien practico el cuso me encanto esta parte. También me ayudo a saber que tengo que reforzar en estadística .

Good course but a little more challenging for me as a beginner and new to SQL. Overall Good

Excellent course and material but it require a lot of practice.

Amazing work guys! I enjoyed the coding part a lot. Thank you!

This Course teaches you real world application of SQL.
