Good content overall. However it will be nice to have the glossary for each week not mixed up with those from previous as it makes it hard to navigate and know which new words need to be learnt

I think this is the most important course in the Google Data Analytics course series. It has equipped me with practical skills for making data reliable for analysis and data-driven decision-making..

Why is this even a Coursera course? There's almost no hands-on component. This might as well just be a free series of videos on YouTube.

This course does not teach data analytics (how to add value with data analysis). It teaches tools used in data analytics.
