Abstract

In this course students are introduced to the rapidly growing field of data analytics with the specific focus on Python programming language. Students will learn concepts, techniques and tools they need to make meaningful inferences from data. Students will be exposed to a real-world data sets to gain practical skills in data manipulations. Each week will involve seminars and coding simulations. In the final project students will build a working code that can be readily applied for exploratory data analysis in their own (future) research domain. To prepare for the class students will have to take the “Programming for Everybody (Getting Started with Python)” course of the University of Michigan at https://www.edx.org/course/programming-for-everybody-getting-started-with-python.
