Use -contains() to ignore columns that contain text. The same function can also be used to remove variables by name range. This pipe can be used to write multiple operations that you can read left-to-right. Build your data science portfolio from the artifacts you produce throughout this program.For example, x %>% f(y) converted into f(x, y) so the result from left-hand side is then “piped” into the right-hand side. This program is ACE® recommended-when you complete, you can earn up to 8 college credits.Īll courses in the specialization contain multiple hands-on labs and assignments to help you gain practical experience and skills with a variety of data sets. No prior knowledge of computer science or programming languages required. Upon successfully completing these courses, you will have the practical knowledge and experience to delve deeper in Data Science and work on more advanced Data Science projects. You’ll learn these data science pre-requisites through hands-on practice using real data science tools and real-world data sets.

The specialization consists of 5 self-paced online courses that will provide you with the foundational skills required for Data Science, including open source tools and libraries, Python, Statistical Analysis, SQL, and relational databases. This Specialization from IBM will help anyone interested in pursuing a career in data science by teaching them fundamental skills to get started in this in-demand field. Data Science is one of the hottest professions of the decade, and the demand for data scientists who can analyze data and communicate results to inform data driven decisions has never been greater.
