About the Course

This course allows you to apply the SQL skills taught in “SQL for Data Science” to four increasingly complex and authentic data science inquiry case studies. We'll learn how to convert timestamps of all types to common formats and perform date/time calculations. We'll select and perform the optimal JOIN for a data science inquiry and clean data within an analysis dataset by deduping, running quality checks, backfilling, and handling nulls. We'll learn how to segment and analyze data per segment using windowing functions and use case statements to execute conditional logic to address a data science inquiry. We'll also describe how to convert a query into a scheduled job and how to insert data into a date partition. Finally, given a predictive analysis need, we'll engineer a feature from raw data using the tools and skills we've built over the course. The real-world application of these skills will give you the framework for performing the analysis of an AB test....

A good course for learning and apply sql to conduct analysis on ab testing results. Would be better if the instructor could provide more info about how to design and apply AB Testing on the customers

The instructor is very smart and her syllabus is very easy to follow. The real life examples are great and helps put ideas in perspective! I would definitely recommend this course and already have!

Если кратко, то не советую. Ни SQL нормально не попрактикуете, ни в A/B тестах не разберётесь.

Много пространных видео, подача информации не очень. Есть задания в которых совершенно не ясно что нужно делать.

This course lacks some structure, overview and professionalism (like editing the videos). Nevertheless, it is a useful of this specialization, if ones has the extra time to invest.

El funcionamiento del curso en si me presento muchos inconvenientes. Aprendi muy poco y basicamente hice lo posible por sacármelo de arriba. Es un curso NO recomendable.

Assumes the student has far more SQL experience going into this class making it exceedingly difficult with little to no resources to assist in solving the problems.

Class contains a wide variety of issues: unclear instructions and assignments, repetitive and less-than-useful information, topics that are barely covered.

The instructor knows SQL but she needs to take some classes on learning design and teaching. The course is somewhat messy and underprepared.
