Explanatory note

This course requires proficiency in R, introductory data analysis and the knowledge of mathematics at the level of Calculus and Linear Algebra. The knowledge of programming is helpful but not required. However, proficiency in English is a prerequisite for academic learning, understanding instructor's explanations, and reporting the results of analyses.

Teaching goals for the course

When working with large datasets, researchers often seek to combine the use of databases such as MySQL and statistical tools provided in R. The goals of this course are 1) to introduce students to relational databases (MySQL and SQLite), SQL language and the tools of accesing SQL databases through R, and 2) to develop their analytical skills by applying basic data mining techniques in their analyses. Students will learn these advanced techniques by working on an individual project. Learning these methods in English is essential because these concepts were developed in English. Knowing these methods will open a range of new opportunities for students: work and study in English speaking organizations, research opportunities and collaborations with international research community.
