“Candidates will be expected to understand the statistical fundamentals upon which most clinical research is based. They may be asked to suggest suitable approaches to test problems, or to comment on experimental results. They will not be asked to perform detailed calculations or individual statistical tests. Candidates will be expected to understand the statistical background to measurement error and statistical uncertainty”.
