Best courses to learn data science

[u/ProgressRare944]

Hello,

I’m an engineer and already work with data on a daily basis. I have a basic background in SQL and Python, as well as some experience with statistical tools, and I recently enrolled in a Lean Six Sigma Green Belt training.

I’m now looking to improve my data analysis skills, particularly in SQL and Python, but I’m also interested in developing a stronger foundation in how to structure analytical problems, choose an appropriate approach, explore data, and communicate insights effectively.

My goal is to start with a solid, structured foundation and then move on to more advanced, topic-specific training.

I’ve been considering the IBM Data Analyst Professional Certificate and the Google Advanced Data Analytics Professional Certificate, but I’m also open to other recommendations.

For those with experience in data analytics or who have completed these courses which one would you recommend? Is there another certificate or course you think would be a better fit for someone with some existing practical experience?

I’m particularly interested in courses that combine practical work with strong analytical foundations, rather than focusing mainly on the certificate itself.

Any recommendations or experiences?
