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 am a complete novice and this course is too advanced for me to complete with only the lessons and information provided in this course. I am currently looking for another SQL course to take that is better at teaching SQL so that I can come back and finish this course in order to complete the certification.

Additionally, the course provides hands on experience that I cannot complete due to not having access to BigQuerry on Google. The BigQuerry appears to be too expensive for me to bite into. The free trial Google makes available does not allow you to complete all the practical exercises.

It covered essential topics like identifying data quality issues, handling missing data, and dealing with inconsistencies. I found the step-by-step approach helpful in learning to clean and transform messy data into reliable insights.

The instructors were knowledgeable and explained complex concepts in an easy-to-understand manner. They provided clear instructions and shared useful tips throughout the course, making the learning process enjoyable and engaging.

What I appreciated most about this course was the emphasis on data integrity and accuracy. I learned how to identify and address common data quality issues, ensuring that my analysis is based on reliable and trustworthy data. The techniques and best practices taught in the course will undoubtedly save me time and frustration in my future data analysis projects.

This is one of the most important sections I have completed in the Google Data Analytics Certification to date. This course introduces you processing data, with a heavy emphasis on data cleaning methodology and techniques. It covers techniques using either spreadsheets functions or SQL to be used when working with databases. I found using SQL to query in BigQuery to be very useful and think that I will utilise that particular platform for performing my own queries with data in future. Getting the opportunity to practice some basic SQL queries, in order to clean data, is very important for an analyst as most of his/her time will be spent cleaning data prior to analysis. The inclusion of preparing documentation and real-world examples, provides a professional standpoint to all of the work involved in this course. The course ends by focusing on how to prepare a data analytics-focused resume and shares some best practices - this element of the course I value greatly and really helps one prepare for the world of working as a data analyst. Very well-structured and well-paced course full of useful knowledge and techniques.

I recently completed the course "Process Data from Dirty to Clean" offered by Google, and I must say it exceeded my expectations. The content was comprehensive, providing a clear and systematic approach to handling data cleaning processes. The instructors were knowledgeable and effectively communicated complex concepts, making the learning experience enjoyable. The hands-on exercises and real-world examples significantly enhanced my practical skills in cleaning and transforming data. The course structure allowed for a gradual progression from basic to advanced topics, ensuring a solid understanding of the entire data cleaning workflow. The interactive nature of the course, including quizzes and assignments, helped reinforce key concepts and provided valuable opportunities for application. Moreover, the course's focus on industry-relevant tools and techniques, coupled with Google's credibility, adds a significant advantage to anyone looking to boost their data processing skills. I feel more confident in my ability to tackle messy datasets and apply the learned techniques in real-world scenarios.

The overall interactivity and timed tests are a welcome addition. I like the clock placed on the quiz efforts. It forces you to really pay attention to the question, and work through a timebox, which I feel assists in developing management. The one issue I had was how the program runs as for overlaps. Some students get caught in the middle of a course reconfiguration. As a result, we lose the results of the quizzes and assignments completed already. This "catch-up" puts us closer to a breaching deadlines from the point of disruption, and worse - any affect of the grade negatively, is something the student does not need.

Other than that - the Analytics program's instructors are all fantastic! I am encouraged by all of them, and feel so much more empowered with the learned and developed skills for an analytics role! Five stars - hands down!

The instructor is lovely, with an excellent sense of humor, the right level of enthusiasm, and above all, very professional. She is very expressive, and it helps to keep us interested throughout the course, even when the coding can be a little on the difficult side some times. Many thanks also, to the team behind the scenes in planning out the syllabus, inserting the right examples at the right time, and for the refresher of concepts scattered across different parts of this course to facilitate the learning in a very smooth manner. As someone from the education sector, i must say that this course is extremely well designed and well planned, with very sound pedagogical practices. Great job, and I love every bit of this.

The course starts with statistical measures associated with data integrity including statistical power, hypothesis testing, and margin of error. Also discussed are strategies that can be used to address insufficient data, the difference between clean and dirty data, characteristics of dirty data, demonstrate an understanding of the use of spreadsheets to clean data.

Finally, the course ends with a discussion of some important parameters to keep in mind while working on a Resume, like understanding how previous experience may be added to a resume, discuss how a data analyst job description may be aligned to a particular area of interest.

Thank you Google and Coursera for this amazing course to start with data cleaning.

good to me.

On your resume, describe how you used and applied your experience in a new project, and what skills you used to overcome any problems you encountered. Actually, I was appointed as a safety driver in Hyundai Motor's self-driving car project, but I studied and experienced related technologies and discovered that Korea's technology was lagging behind because of the too engineering parts of the engineers. For now, I want to devote myself to playing a role of creating a reference point for transitioning from a national project to a sophisticated technology, and in the future, to have an educational environment for my future generations.

I absolutely love the diversity in the presenters for each of these courses in the program. The presenters were very knowledgeable but were excellent in breaking down the information in a beginner-friendly manner. There was so much content, but possible to learn and understand. I really loved the interactive lessons that gave the learner the plenty opportunity to practice the new content within each lesson. I really enjoyed this program that helped me to learn what I needed to learn without feeling overwhelmed. It was also extremely helpful that the design of the new information was always presented in a manner that real-world applications.

I have learnt spreadsheets functions and SQL along with Data Integrity and how process of Dirty to clean the data using SQL and Spreadsheets formulas , I'm really enjoyed this course and Some mistakes have done due to not understanding small things like some SQL functions but still made better score by understanding and Reviewing the videos and notes . Kaggle is something is not understand because of confusion of datasets In Big Query . Still a lot to learn in SQL and Spreadsheets

Some questions looked tricky but to want to improve better with regular practice .

Great follow up from the other courses on this certificate, it does have some very basic things but also more advanced highligths and examples that are interesting. I felt it has a good video pace for the subjects covered by each lesson, I liked most of the examples from the readings and quiz activities, good practicing for checkin on the data cleaning process I already do, I will propably work better with some recommendations that are given during the course such as better logging of cleaning steps that are done over the dataset being prepared for processing.

The instructor and her way of explanning the things is super awesome. I will fill honored, if I will get a chance to connect with her over LinkedIn and get guidance especially in data cleanning part of data analytics. I tried to find Sally on LinkedIn, but their are so many with same name. So, if I will get excess to her LinkedIn profile, it will be really helpful for me to connect with her.

So, hope someone who is reading the reviews, will definetly revert via mail. eishuarora498@gmail.com

Thank you so much #Google,#Sally for making my journey easier.

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

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.
