I'm glad I took this course. The instructor is warm, upbeat and very clear. The materials are very informative and helpful. I gained more understanding of cleaning data as well as built my SQL skills.

Probably one of the more technical courses of the program developing your technical skill set and actually preparing you to become a data analyst by introducing more hands-on Excel and SQL exercises.

I began the course with some basics of concepts but no real useage of Google Sheets or SQL. It was a challenge to get familiar and comfortable to start but by the middle of the section I felt at ease not only navigating and using the functions in Sheets but also setting up the SQL Query. That's not to say it came easy but the manner in which the instructor provided each lesson and the integrated method of instruction then practice with addition of information in each part made the learning easier for me.

Like all other cousrse in this spelizaton program "process data from dirty to Clean " was also fantastic to leearn the concept of data analysis. we learned how to clean data from by using the tools like spreadsheets and SQL. Also there was a useful guidelines to build resume to get our first entery level data analyst job. The hands on activiy and self reflection section was very helpful to boost my self confidence. Last but not the least I should mention the weekly challneges and the Course Challenge.

Honestly loved the course. You learn so much and also have access to the lessons as a refresher in the future. There were maybe a handful of times that I didn't understand something, but with a little practice in between lessons I was able to fix those mishaps. Honestly just noting everything down, like the formulas, really helps and allows you to kind of quiz yourself when you're away from the course. Awesome lessons, teacher, and homework to better help me on my journey to becoming a data analyst. :)

All I can say is that this course is too long... but too long for a reason. It is a full-packed course where I learned everything I need to know to process and clean data and prepare it for analysis.

What I like are the hands-on activities wherein you follow the step performed by Sally, the instructor in demonstrating how to use Excel functions and SQL commands to do cleaning of the data.

These activities will get your hands 'dirty' to be able to clean data. Thank you for another great course, Google!

I would rate it as 4.5 stars. The course overall is great, and Sally is a great instructor!! But I wish it has more text resources for SQL queries. You really need to save notes and make prints from the videos, to have material to read after that. Personally, if I need to refresh something, I prefer to read instead of watching videos again. And this was something the previous courses did an amazing job, and I think this one could improve: having lectures summarizing the fundamentals of SQL queries.

I found this course as the one from which I get the most information and with which I feel closer to being a data analyst. Even the last part of the tips on resumes and interviews was very helpful.

Most of the classes were carried out very well and each one had very useful information not only technically but also in the details that we must take into account when working with our data, even those videos that only shared an experience taught me things to keep in mind as a data analyst.

Great!!! this course on my opinion is THE FUN ONE and the MOST ENJOYABLE. not that all of the rest are boring but this one is just FUN. however, Using BigQuery... it was free for the first 4 days then every time i tried to log in they want to charge me... they said they wont but they did. and they do not accept Pre-Pay Cards either. i asked around and it seems that it only happened to me. maybe a bug. but other than that! SQL and cleaning data is just FUN!!! LOVE THE INSTRUCTOR!!!

Such a great instructor, with easy to follow steps that allow almost anyone to understand what she is talking about. In the beginning, I didn't realize the amount of information I would get from this course. In my perspective, this course is super great. A lot was taught, even though I was not familiar with some of the tools that have been introduced, great references were also given. These references would allow me to practice and build my confidence with these tools.

I liked the instructor a lot. All courses in this Google certificate series are absolutely amazing. Great structure, short videos, using multiple forms (video, text and other). Playing with motivation, interesting external information and most of all, not just theory - practical exercises as well. Probably the best course (meaning the serie of all 8 courses) I've ever done. Even though the topic is not so easy, it's presented in a very simple and understandable way.

I just wanted to express my appreciation for the incredible learning experience I had with the course instructors. Their detailed and step-by-step approach to teaching the material was impressive. The course structure was well-planned, with each lesson building on the previous one, making it easy to follow along and understand. The instructors were knowledgeable, patient, and supportive throughout the entire program. Thank you for a fantastic learning journey.

as much as I am trying to find the most brief lectures and straight to the points, I find this painfully lengthy, but I totally I understand why! this course deal with all kind of mentalities , and with people starting from scratch. I am not an expert per see , it is just find it many things intuitive and this course can be shorter , however it is comprehensive. Thank you google so much , this is one hell big effort to make such comprehensive courses.

Excellent not only in the technical details that, although basic, fulfill the purpose of introducing concepts that might be difficult in an online course. The most important is the link with the reality of someone transitioning into a new career in data analytics. As a Neurobiologist, I have a long history with data analysis but not with SQL or the needs of industry. Here I have received a lot of great advice and I am putting it into practice now!

The course is impeccably structured, offering clear and comprehensible guidance throughout. Sally's motivational approach is truly inspiring, and her instructions are easily digestible. The exercises provided in the course offer hands-on experience with spreadsheets and Big Query, while many practical tips for data cleaning proves beneficial. I highly recommend this course for anyone seeking to enhance their skills in data analysis and processing.

I do learn a lot enrolling this free online Google Course. From course 1 to 4, my exposure to data has broaden my knowledge and skills which I have not applied in my 36 years of government service. I was focused on my job considering that I was alone working my sector, due to lack of manpower in our department. It is my passion working with statistics and I do really enjoy working with numbers. I am so thankful to be one among of your enrollees.

This course had so much informtation and vocabulary to learn. It is can be intimidating yet very rewarding. I found this course to be very eye opening regarding what it will take to make ma a great data analyst. Completing this course certification is only one part of being succesful in this field. Learning SQL, Python, R, Tableau are just a few other programs that I will need to learn to help propel me in this field. Nervous yet moving forward.

The course is very useful and interesting since it covers topics related to data integrity and data-cleaning, the tools and processes used for this purpose whether related to SQL or spreadsheets. Also, the course covers the importance of connecting business objectives to data analysis and data-cleaning. Least and not last, the course covers issues related to clean and dirty data, in addition to documenting the data-cleaning processes

This course focus on the data cleaning process, which is taught by Sally. I especially like the way she delivers every lesson, as it is enthusiastic and understandable to me. The content is straight to the point, with a balanced mixed between theoretical and practical materials. Overall, I learnt a lot from this course. Thanks Google and Coursera for offering this course here with a reasonable price. Please keep up your good work!

Albeit I am yet to fully grasp the less frequently used SQL query statements, this program has been great so far and if I have to recommend a data analysis learning programme, it most definitely is this course! Can you imagine a programme that even guides you through Resume building and what you should and should not include?... beautiful indeed. Thank you to all the instructors so far. Very many thanks to Google and Coursera.

Lots of information to learn. I feel like this course organized the important tools we need to know for each section. Lots of terminology heavy words that also have a function and each one is emphasized during examples. It was very difficult for me this course was way more technical than the previous courses because of it intersects with statistical thinking despite there being no math. I found this course very challenging.

The course explained all the concepts related to data cleaning and skills needed to do it. The instructer was very energetic and was able to drive home all the topics that were discussed. The best thing about the course was that it offers scenerios where you imagine yourself in the shoes of an analyst and do various jobs. The hand-on activities were also very engaging and an excellent resource to practice the skills.

It was an enjoyable course, instructor was great - an ever smiling face and in a way took a lot of pressure off from my shoulders w.r.t. not knowing SQL much. Lots of examples for SQL and Spreadsheets. Overall, a great experience. I also loved the part of guilding us on resumes, including suggested playlists on YouTube w.r.t. interview questions, Kaggle etc. Thank you Sally, Measurement & Analytical Lead :) :) :)

Sally is absolutely the best. She's a well versed teacher; I could see it in her miles away. Thank you for holding by the hand and leading me through the process stage. This course is loaded, and intriguing( my most challenging course so far in this specialization.) You would surely want to stick around and successfully complete it, if you have that problem solving skill. Thank you, for this amazing piece!

This course is structured really well, especially for those who have no background in data cleaning and processing. Even though I've been self-studying SQL, I've also learned some new functions from this course. I also appreciate how the instructor relays the lessons clearly and straightforwardly. This course could be one of my favorites, so far. I learned a lot of new things!

Thank you for your hard work!
