#### Aims

- To equip students with the skills to import, explore, manipulate, visualise and report real data sets using the statistical programming language R.
- To introduce students to the concepts and mathematics behind sampling and sampling- based estimators.

#### Content

- Modern usage of R.
- Data import, clearning, wrangling and exploration.
- Visualization, plotting, exploratory data analysis.
- Application, methods, theory and coding of simulation based approaches to statistics.
- Monte Carlo hypothesis testing, non-parametric and parametric Bootstrap.
- Approximating expectations of random variables by Monte Carlo and general Monte Carlo integration. Accuracy of approximations.
- Simulating random variables via simple Monte Carlo methods (inverse transform/rejection/importance sampling).

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will:
- have a solid foundation in the R programming language;
- be able to import and manipulate real world data sets using modern libraries in the R ecosystem;
- be able to perform an exploratory data analysis including a variety of visualisations;
- understand the mathematics (methodology and theory) of sampling-based estimators and simple Monte Carlo simulation;
- be able to use simulation approaches and apply the mathematics of sampling-based estimators to real world statistics problems.

Subject-specific Skills:

- Students will have foundational skills in data science, specifically in data import, manipulation and exploration.
- Students will have foundational skills in simulation and sampling-based methodology.

Key Skills:

- Students will have basic mathematical skills in the following areas: problem solving, modelling, computation.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Computer practicals consolidate the studied material, explore theoretical ideas in practice, enhance practical understanding, and develop practical data analysis skills.
- Tutorials provide active problem-solving engagement and immediate feedback to the learning process.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formative assessments provide feedback to guide students in the correct development of their knowledge and skills in preparation for the summative assessment.
- Computer-based examinations assess the ability to use statistical software and basic programming to solve predictable and unpredictable problems.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
