This unit introduces the statistical and probabilistic concepts that are the basis for the study of bioinformatics. Topics covered include an introduction to probability and conditional probability, probability distributions, sampling distributions and an introduction to Markov processes. Particular attention is paid to how they relate to specific applications in the field of bioinformatics. The unit is a prerequisite for STAT817 (Bioinformatics) for those without a statistical background. A basic understanding of calculus would be an advantage. However, all calculations will be carried out using Excel and Scientific Notebook.
