Course Purpose and Objectives

The aim of this course is to introduce students to data science, big data analysis and statistics for data science, providing both the necessary theoretical and practical skills.

This includes a focus on statistical methods for data scientists, including an introduction to probability theory and linear algebra, inference and estimation, as well as topics on model evaluation and hypothesis testing. To develop a set of practical skills and tools in terms of visualizing, exploring, storing and processing data, and an introduction to big data and data science tools.

Learning Outcomes

By the end of the course, the students will have a good grasp on statistical knowledge related to data science, and be able to apply this knowledge to data using modern tools and libraries. The students will also be able to perform exploratory data analysis and visualization, data pre-processing, and basic techniques for predictive analysis and model evaluation. Students will also be taught in Python, which will form the basis for all following courses.

Summarizing, by the end of the course students should be able to:

• Explain and apply statistical knowledge related to data science on real-world datasets, using modern tools and libraries
• Perform exploratory data analysis and visualization on datasets with different properties
• Perform data wrangling, manipulation, and data cleaning, to get usable datasets for downstream tasks
• Knowhow to access, manage, and store big data for analysis, while also using High- Performance Computing

Apply basic techniques in predictive analysis and model evaluation.
