The statistical analysis techniques taught here form the foundation of any analytics or data science practice.
This selfpaced class is an excellent handson walkthrough of the most foundational techniques used to understand and ask questions of datasets. The statistical techniques taught in this workshop underpin virtually every common method for analyzing data. They also provide a practical, useful introduction to contemporary data science techniques.
This program comprises roughly five hours of expertled content, with basic assignments and exercises you can participate in between chapters.
