Course Overview

NYC Data Science Academy is now offering an R Intensive Intermediate course: a five week course designed around students who have taken NYC Data Science Academy's R Beginner course or for those who already have a firm skill set and understanding of R. The goal of this course is to bring our students to a near expert level.
Be sure to read the course syllabus below to ensure your level is appropriate.

Why R is important

R is a free, full, and dynamic programming language that, since its release in 1996, is on course to eclipse traditional statistical packages as the dominant interface in computational statistics, visualization, and data science. As an open-source platform, R has grown to become an incredibly flexible tool that can be applied to nearly every graphical and statistical problem, at virtually no cost to the user. The community of R users is continuing to build new functionality.

Project Demo Day and Certificates

From data mining to time series models, the course ends with a demonstration of a project of your choice on Project Demo Day.
On Demo Day you will showcase a project of your choosing, utilizing the tools and skill sets taught to you throughout this course. We encourage you to be creative! Students have chosen projects ranging from digital marketing simulation to finding the relation between people using natural language processing. The possibilities are nearly endless!
After the successful completion of the course, you will qualify for one of three certificates: Extraordinary Standing pass, Honorable Graduation pass, and Active Participation pass.
Certificates are awarded according to your understanding, skill, and participation.
