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.

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!

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.

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 was great with explaining the process of cleaning data and I enjoyed the content; including the hands-on experience working with BigQuery sandbox. I chose not to sign up for a free trial, so I did not have the ability to update data in BigQuery, but was still able to follow along. I think I learned what was expected from this course and I enjoyed the instructor's pace. Thank you.

P​ertaining to a quiz question "You decide to use a spreadsheet function to divide the text strings in Column G around the commas and put each fragment into a new, separate cell. You are using the SPLIT function."

T​he answer assumes your using google sheets, SPLIT is a function within the GSheet enviroment, however in excel its a tool, not a function so this True/False question can go either way.

S​ally is one of the best instructors. Professional and also authentic style to engage students watching videos. For what was a lot of detailed information, her speech, intonation and hand gestures, combined with her personality made her credible and likable. So many people in videos are so monotoned, I find it hard to stay engaged. Great job also with encouraging students. Not fake “cheering on.”

Great course with some excellent content as well. I enjoyed the practical examples more. All this helped with my overall undersatanding of the course material and te subject matter overall. With some more practice on the material presented and the applicable resources, I am sure that if I keep practicing I will be able to polish my skills in this world of data analytics which is rather new to me.

Another great course in data analyst series. Course content is great covering spreading sheets and SQL for cleaning data and making it ready for futher action. The best thing in this course was that a complete week was dedicated to resume building which might be boring for some but for many its great to have. I would higly recommend this course to all who want to become data analyst in future.

T​his course is excellent in providing an overview of common spreadsheet functions used in data processing. It also takes a deeper look into cleaning and processing data with SQL using common statements and syntax. In just a few short weeks you can really start to gain traction as a data analyst. The course instructor is very knowledgeable and presents the information clearly! Great experience!

This course is amazing if you want to learn about data cleaning in general. You will learn a lot of pre-cleaning and cleaning techniques using spreadsheets and SQL , also you will know how to verify and report the integrity of your data. Additionally, it contains very good tips to improve the way your information is showing in your resume or build one if you do not have one. 100% recommended.

R​eally well designed course. Very valuable material especially the SQL part. Adding the resume & job search section was the cherry on top. It's very thoughtful of the course designers to include that section in this course, it has very useful information & it makes learners feel they have a better picture of what to expect & how to navigate after finishing this program. Very Well Done !

I love the instructor of this course. She spoke a good speed, clearly and with a lot of enthusiasm. She was always very energetic and happy in every video. I wish she will give more courses.

Also I like the sql and spreadsheets formulas I learned to make cleaning data verfy easy. Some of this option i didn't know so it was great that it was explain and show how you can use them.

Delivering lots of knowledge & bring it up to high level.

Need to improve SQL compiler download version instead of web site to get better & more practice.

Also spreadsheets should be more sample data to practice more.

I really enjoyed & have to give up to spend my personal time.

I could recommend this course to anyone and planning to translate English to Korean.

Great course and super interesting. One thing I would note is that the graded assessments mostly test concepts rather than skills. It would be nice to have a couple of questions that ask you to actually write a basic SQL query or clean a piece of sample data in the same way you get to do in the practice exercises. Otherwise, great job!

Well paced course. A gentle introduction to SQL and formulae and functions in spreadsheets. I had already used many of the cleaning techniques illustrated in the course in my job, but this neatly formalizes it. The section on resume building was very helpful for people like me who are looking to change careers!

Great course! T​his was one of the best courses overall. The instructor, Sally, was incredibily good in her content delivery and mastery. Through this course, I got exposed to different Spreedsheet and SQL functions that will help me in analyzing small and big data. I have no regrets taking this course.

A great instructor. The course dives deep into data cleaning, provides many useful functions and query statements to use to clean the data. Though, some of them were already familiar to me, it was great to refresh them and see in a new light how they can be used for the purpose of data cleaning.
