Data skills are the cornerstone of the 21st-century workforce, and SQL is foundational for any role that involves data. Understanding and effectively using SQL can open doors to greater productivity, better decision-making capabilities, and more career opportunities in this era of digital transformation.

You might know SQL as a querying tool, but in this live training, you will see how SQL can help with predictive modeling. In this live training, we will teach you how to unlock a new dimension of your analytical power by bringing simple linear regression into SQL! Specifically, we will use a sales dataset and learn how to create a regression to find the quantity sold as a function of price. Furthermore, we will do a more sophisticated pricing anlaysis by finding the theoretical price that maximizes revenue —all within SQL.

Key Takeaways:

Learn how to find the coefficients for a simple linear regression in SQL
Discover how to use SQL to analyze pricing data and find the answer to an interesting optimization problem, which is finding the price that maximizes revenue
Become good at SQL aggregate functions and common table expressions (CTEs)
