ST121 Statistical Laboratory

Please note that all lectures for Statistics modules taught in the 2022-23 academic year will be delivered on campus, and that the information below relates only to the hybrid teaching methods utilised in 2021-22 as a response to Coronavirus. We will update the Additional Information (linked on the right side of this page) prior to the start of the 2022/23 academic year.

Throughout the 2021-22 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and on-campus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information.You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

All dates for assessments for Statistics modules, including coursework and examinations, can be found in the Statistics Assessment Handbook at http://go.warwick.ac.uk/STassessmenthandbook

Introductory description

This module runs in Term 2.

This module is not available to students within the Dept of Statistics, who take ST117 instead. This module is available for external students who have taken the necessary prerequisites. This module will be useful for ST231 Statistical Modelling and other modules which use statistical data analysis such as ST340 Programming for Data Science and ST323 Multivariate Statistics.

Pre-requisites for non-Statistics Students: ST120 Introduction to Probability.

Module aims

To introduce students to the R software package, making use of it for exploratory data analysis and simple simulations. This should deepen and reinforce the understanding of probabilistic notions being learnt in ST120.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Introduction to R
Exploratory data analysis: methods of visualisation and summary statistics
Sampling from standard discrete and continuous distributions (Bernoulli, Geometric, Poisson, Gaussian, Gamma)
Generic methods for sampling from univariate distributions
The use of R to illustrate probabilistic notions such as conditioning, convolutions and the law of large numbers
Examples of modelling real data (but without formal statistical inference) and the use of visualisations to assess fit

Learning outcomes

By the end of the module, students should be able to:

  • Gain familiarity with the R software package, making use of it for exploratory data analysis.
  • Use R to simulate samples from a variety of probability distributions.
  • Gain the ability to propose appropriate probabilistic models for simple data sets.

Subject specific skills

Select and apply appropriate mathematical and/or statistical techniques.
Create structured and coherent arguments communicating them in written form.
Communicate subject-specific information effectively and coherently.
Analyse problems, abstracting their essential information formulating them using appropriate mathematical language to facilitate their solution.
Select and apply appropriate statistical programming language (for example, R) for exploratory data analysis

Transferable skills

Critical thinking: extracting patterns from incomplete data and using them to form evidence-based conclusions.
Problem solving: use of logical reasoning to build arguments grounded in evidence and with explicit underlying assumptions.
Self-awareness: monitoring of your own learning and seeking feedback.
Communication: verbal discussion of ideas in seminars and among peers; written communication in assignments.
Information literacy: evaluation of data and uncertainty in a model-based way.
Digital literacy: use of computational tools to understand and visualise data, and to produce reports.
Professionalism: self-motivation, taking charge of your own learning, and prioritising effectively.

Assessment group D
Weighting Study time
Laboratory Report 1 15% 15 hours

The first report will emphasise on R coding skills and/or other statistical questions.
The number of words noted below refers to the amount of time in hours that a well-prepared student who has attended lectures and carried out an appropriate amount of independent study on the material could expect to spend on this assignment. 500 words is equivalent to one page of text, diagrams, formula or equations; your Laboratory Report 1 should not exceed 15 pages in length.

Laboratory Report 2 15% 15 hours

The second report will emphasise on R as a simulation and visualisation tool and/or other statistical questions.
The number of words noted below refers to the amount of time in hours that a well-prepared student who has attended lectures and carried out an appropriate amount of independent study on the material could expect to spend on this assignment. 500 words is equivalent to one page of text, diagrams, formula or equations; your Laboratory Report 2 should not exceed 15 pages in length.
