This module illustrates the application of statistical techniques to health related research. Methods are applied using data from real-life studies, and the importance of statistics for making healthcare decisions is emphasised. No prior knowledge of medicine or biology is required. The module commences with a revision of hypothesis testing and statistical inference procedures. This is followed by four main topics: epidemiology, survival analysis, clinical trials and meta-analysis. Epidemiology explores how statistical methods are used to identify risk factors for disease onset, and to identify accurate tests for diagnosing and screening disease. A range of techniques (including regression) are described for quantifying the association between a factor (such as, smoking, eating beef, using a mobile phone) and the subsequent development of a disease. Survival analysis looks at the features and analysis of data from studies of long-term patient outcomes, for example time to death in those with cancer, and statistical techniques are described for modelling survival trends and identifying factors that improve survival. Clinical trials are immensely important for evaluating the effectiveness of a new treatment, and their design and analysis are considered in-depth, including randomisation and sample size calculations. Meta-analysis is crucial for evidence-based medicine, as it summarises results from multiple studies to provide overall answers to inform clinical decisions (e.g. about the best treatment to use). Core meta-analysis methods are described, and issues such as publication bias addressed. The module is a perfect foundation for a subsequent postgraduate degree in (Medical) Statistics or Data Science.
