Excellent course, although I feel a little deeper explanation of SQL is needed for those that aren't very familiar with it.

A good course, however more SQL functions can be added which can be handy with informing of the nested statements in SQL.

Excellent presentation, examples we can connect with.

This course and others done earlier have great tutors. Thanks to all.

I would like to see a chapter where how to treat nulls, errors and other fixes, when to delete dirty data, when to fix it

satisfied with the resume section but you could have add more about the actual process part. it was not much of challege

Covered lots of info, this instructor was great and sounded natural. Much easier to listen to than the others so far.

Sally instructor is too good to explain and energetic person. I prefer to learn more in future in coursera google.

This course has helped me to get a good grasp of the basic concepts of data analysis, spreadsheets and using SQL.

It was great. The content was well delivered in a smooth and relatable mode. Kudos to Sally on a job well done.

Course was first rate and very informative. I learnt a lot about cleaning data and tools to use to clean data.

Me gustaria que se explique un poco mas de SQL, pero entiendo que eso lo veremos mas adelante en otros cursos.

I learned a lot. From simple functions and using other applications. Thank you for this wonderful opportunity.

Appreciated the way the learning was provided, added knowledge to Data cleaning skills, once again Thank you!

El curso trata varios temas interesantes aunque me gustaría que fuera aún más aplicado mas que todo en SQL.

I thought the course was good overall but there were some glitches in the add on and Big Query activities.

The course is well organized and easy to understand but it is really too long. The instructor is great !!

sometimes when doing tick the correct answers, there are many correct looking answers and confuses us alot

I don't like and understood how to use big query. I hope google have used other websites for SQL practice.

Resume section had some interesting points but I think it should have been optional. Loved the intructor!

I enjoyed this course very much... It's taken me a step closer to my dream of becoming a data analyst.

Not enough independent practice that required critical thinking and application of code being learned

Introduced basic spreadsheet and SQL functions, it's a good start. There are more self-study needed.

its a wonderful course to get started to know and do data cleaning work and perform the tasks well.

I like this course, but I would recommend implementing an open source SQL for this course teaching.

encuentro que para ser 5/5 solo le faltaría incorporar proyectos mas grandes de limpieza de datos
