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.

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!

This course really started getting the student "Me" more accustome to using SQL in the BigQuery Database. I really enjoyed the ability to initiate queries on a 400GB dataset. Realizing the sheer size of that accomplishment that happens in a meer 15 sec is absolutely amazing. This is an incredible course.

I had a lot of challenges with this course but I would like to revisit the course material and do the practical areas again so that I get to understand the material. The lecturer explained the material in a very detailed way. I had challenges because it ws my first time doing data cleaning practically.

Great course! This 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.

5 star for me because everything i learnt is new to me and got to learn about SQL and new EXCEL functions.

however, i only wish that the BigQuery access can be expanded without quota limitations for Coursera subscribers at least, if not for anyone

Recommend this to anyone new to data applications.

The course was / is excellent, except for few glitches where it is not updatad or synchronised with videos.

The Teacher Ms. sally Kim is an extra ordinary person, she knows her subject very well and so fluent that is simply great. I would love to see her again in any video(s). My salute to her.

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.

It is very interesting course as it gives very informative and realistic information. It tells that why data cleaning is necessary, how we can clean the data in spreadsheet and sql. Brilliant course. Especially I liked the way of explaining the functions by using the real life example problem.

Hands-on activities are by far the most amazing feature of this course. If I divide all the knowledge and skill, I gained from this course then 50% of them came from the Hands-on Activities. Thanks, Coursea and Google for making this amazing course series. Love and respect for both of you.
