#### Aims

• To equip students with the skills to import, explore, manipulate, model and visualise real data sets using the statistical programming language R.
• To introduce students to the concepts and mathematics behind sampling and sampling- based estimators.
• To introduce students to the importance of data protection and governance issues in working with data.

#### Content

• Modern usage of R.
• Sampling (finite, stratification, clustered, ...).
• Visualization, plotting, exploratory data analysis, data cleaning, reporting tools.
• Data protection / governance.
• Approximating expectations of random variables by Monte Carlo. Accuracy of approximation. Sources of randomness.
• Generating random variables (inverse transform, rejection methods, importance sampling, discrete).

#### 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 of sampling-based estimators and simple Monte Carlo methods.
Subject-specific Skills:
• Students will have foundational skills in data science, specifically in data import, manipulation and exploration.
• Students will have foundational skills in 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.
