# Module Overview

### Statistics I

This module introduces probability theory, random variables, probability distributions and statistical inference. The fundamental laws of probability including Bayes' theorem are covered. Motivating random variables as a mapping of experimental results onto subsets of the real numbers, this module covers the mathematics of probability including the standard univariate discrete and continuous distributions. Statistical inference for a population mean/proportion are also covered. Descriptive statistics and data visualisation are briefly reviewed.
