## Statistics for Data Science

#### Version 1.0

This course introduces the basics of carrying out a statistical analysis in Python. It covers exploratory data analysis, constructing and interpreting linear and generalised linear models, and introduces Bayesian modelling.

#### Course objectives

By the end of the course students will be comfortable implementing and interpreting linear models and generalised linear model in Python and be familiar with the concepts of Bayesian modelling.
