课程概述

This is the third course in the Google Data Analytics Certificate. As you continue to build on your understanding of the topics from the first two courses, you’ll be introduced to new topics that will help you gain practical data analytics skills. You’ll learn how to use tools like spreadsheets and SQL to extract and make use of the right data for your objectives, and how to organize and protect your data. Current Google data analysts will continue to instruct and provide you with hands-on ways to accomplish common data analyst tasks with the best tools and resources. Learners who complete this certificate program will be equipped to apply for introductory-level jobs as data analysts. No previous experience is necessary. By the end of this course, learners will: - Find out how analysts decide what data to collect for analysis. - Learn about structured and unstructured data, data types, and data formats. - Discover how to identify different types of bias in data to help ensure data credibility. - Explore how analysts use spreadsheets and SQL within databases and data sets. - Examine open data and the relationship between, and importance of, data ethics and data privacy. - Gain an understanding of how to access databases and extract, filter, and sort the data they contain. - Learn best practices for organizing data and keeping it secure....

I love how the course it's not limited to teach about the technical skills of a data analyst professional, but it also helps you discover some soft skills that make you a better human resource.

I enjoyed this course very much and have gained so much through Hallie teacher and how to connect with others. She is a great teacher and a mentor . All her learnings are great part of my life.

I may have to give up on this course at this point. The instructions in Coursera are not matching what I see in BigQuery. I'm just lost at this stage.

Redundant.

Instructor quizzes arranged in such a way as to be intentionally tricky.

Not clear, not instructive, distracting style

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

Course is over-simplified. Author spent way to much time to create new naming conventions.
