ST112 Probability B

Throughout the 2020-21 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 The contact hours shown in the module information below are superseded by the additional information.You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.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 and follows on from ST111 Probability A and is an optional module which leads to numerous statistical, probabilistic, operational research and econometrics courses. You may be interested in this module if you wish to undertake further statistics modules.

Pre-requisites: ST111 Probability A
Post-requisites: ST104 Statistical laboratory, ST202 Stochastic Processes, ST220 Introduction to Mathematical Statistics

This module is not available to students who have their home department in Statistics, who take an equivalent module. Students who are considering transferring to a course in Data Science, Mathematics & Statistics or MORSE at the end of their first year should take this module.

Module aims

To lay the foundation for all subsequent modules in probability and statistics, by introducing the key notions of mathematical probability and developing the techniques for calculating with probabilities and expectations.

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.

  1. The notion of a random variable and its distribution. Examples in both discrete and continuous settings. Probability mass functions and density functions. Cumulative distribution functions.
  2. Joint distributions. Independence of random variables.
  3. Expectation of random variables. Properties of expectation.
  4. Variance and Chebyshev's inequality. Covariance and the Cauchy-Schwartz inequality.
  5. Addition of independent random variables: convolutions. Generating functions, Moment generating functions and their use to compute convolutions.
  6. Important families of distributions: Binomial, Poisson, negative Binomial, exponential, Gamma and Gaussian. Their properties, genesis and inter-relationships.
  7. The law of large numbers and the Central limit theorem.
Learning outcomes

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

  • Apply the theory of probability distributions, expectation, variance and covariance associated with random variables.
  • Compute and apply generating functions for univariate random variables.
  • Interpret problems and select appropriate distributions to create probability models.
  • Apply the law of large numbers and the central limit theorem to probability models.
