Probably one the more important courses in the specialization. I love how this course made it clear the importance of having a data cleaning checklist. it was well structured with TONS of resources to help with one of the most " at the analyst's discretion" tasks.

As you can imagine, the act of processing and cleaning the data (so that it is accurate) places a LOT of responsibility on the analyst to get it right. And with so many things that need to be done, this course lays out everything you should be looking for.

Highly recommended.

The course is designed for people without much data analytics experience. I like it that things are taught in a clear progression manner with everything divided into bite sizes for you to understand and practise. Even though I am pretty familiar with spreadsheets already, it still serves as a good revision and casts a new light on the processes that I am used to. I also want to give a special mention to the instructor in this session. She is very encouraging and clear which makes the learning experience more alive and engaging.

Me gusto mucho el curso y lo mejor es que aprendí una nueva forma de buscar datos usando SQL, si me hubiese gustado mas videos y/o mas laboratorios usando SQL porque me parece algo demasiado útil y usar SQL en laboratorios realmente me ayudo a entender un poco mejor como funciona este lenguaje si Google pone mas practicas de laboratorios usando SQL seria mucho mejor ya que tiene una herramienta genial que es BigQueary pero que creo que con los estudiantes de este curso se esta desperdiciando un poco por falta de laboratorio

The "Process Data from Dirty to Clean" course by Google on Coursera is an excellent resource for beginners in data processing. It offers a practical and hands-on approach to understanding spreadsheets and SQL. The course's real-world examples and emphasis on application make it highly valuable. The well-paced structure and interactive assessments contribute to a solid foundation in data processing skills. I highly recommend this course for those looking to enhance their practical knowledge in managing and cleaning data.

I really loved this course. This course covered theoretical as well as practical aspects of data cleaning. The mentor seems to be really friendly. Though the course is online but the mentor made it enjoyable and fun. I loved her way of teaching and guiding, especially SQL. She was not only teaching about data cleaning but was also telling about her experiences which made this course worth learning. Not to mention, Sally's energy is contagious. Thanks Google and Sally! Looking forward for same kind of courses ahead.

WOW 100% SPOT ON THIS COURSE DRILLS THE LEARNER, THE LESSONS ARE SPOT ON THE STUDY ON SPREADSHEET AND SQL LEAVES NO STONE UNTURNED THE TUTOR WAS EXCELENT BEING A FIRST TIME LEARNER ON SQL FEELING LIKE THIS IS WHAT I REALLY WANT TO LEARN.

THE SQL WAS SO CHALLENGING BEING MY FIRST TIME WITH BIGQUERY KAGGLE ETC BUT AT THE END OF THE DAY OVERCAME THE CHALLENG SOMETIMES HAVE HAD TO GO BACK TO LESSONS OVER AND OVER AGAIN.

THIS IS REAL LEARN REALLY HAPPY TO BE A PART AND AM PROUD I KEEP HAVING INTEREST AND PROGRESSING

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!!!

This program had all the basic information needed to get started with data cleaning and the best practices. The external link provided were really helpful and very useful. It helps us to build on our data cleaning skills further. Some of the tab options mentioned in the video are little different, but it can be found easily. I really appreciate the effort put in this module regarding building your resume and sharing video links for data analyst hiring and interview process.

So far this was the best module yet, the information presented was clear and the resume part at the end was an unexpected bonus. I am a webmaster at a community college and spent hours in BigQuery using the G4 data I have been collecting from the website. I realized I could expand on that data by pulling in admissions data, exit data, transfer student data, etc etc etc AND use that data to look at our website differently and make adjustments to improve the student journey.

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.

Have a nice day, my teacher. Thank you for this course. This is nice work, teacher! I have completed this course, which is like full gratification! Employers appreciate these kinds of classes and can appreciate what's needed. I have developed during my learning. There is an opportunity to feature this project in my portfolio and add details to illustrate my rational thinking and skills. My recently completed course would look great on my profile.

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.

I’m really happy with how the process transformed the data from messy to clean! The steps were clear and easy to follow, making it simple to fix errors and ensure everything was accurate. I especially appreciated how the guidelines helped in identifying issues and removing duplicates effectively. This tool was incredibly helpful and made managing data much smoother and more efficient. I’m truly grateful for the support and improvement!
