In the health and medical life sciences industry a statistician is responsible for designing studies, analysing complex biomedical data, and ensuring that research findings are valid and reliable. In clinical trials, they determine appropriate sample sizes, randomisation techniques, and statistical models to assess the safety and efficacy of drug products, medical devices or treatments. In medical research, statisticians collaborate with biomedical scientists to analyse experimental data, identify patterns or trends and validate findings. They contribute to developing robust research designs, performing hypothesis testing and interpreting results. They also play a key role in quality improvement by applying data driven methods to enhance healthcare processes and outcomes. Statisticians in this industry work in offices across pharmaceutical, biotechnology and medical technology companies, contract research organisations (CROs), universities, research institutions, not for profit and government organisations, pharmaceutical, biotechnology and medical technology companies and contract research organisations (CROs).

Statisticians use computers at all stages of their work, from the initial survey design right through to the interpretation and presentation of their findings. They frequently use specialised programs to assist in sorting and manipulating the data in order to better identify trends and understand the relationships between different factors.
