## 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.

#### Learning objectives

- What is tidy data?
- What is a variable, value, and observation?

##### Several Python commands to explore the structure of the data

- What is the difference between a continuous and categorical variable?
- What is variation and covariation?
- Where Exploratory Data Analysis fits within data analysis;
- How to use plots to explore variation in continuous variable and categorical variables;
- How to use plots to explore covariation between two categorical variables, two continuous variables or a categorical and continuous variable.

##### Model Basics

- What is a model family and fitted model?
- What is the difference between a response and an explanatory variable?
