|Biostatistics is particularly concerned with disentangling these different sources of variation. It seeks to distinguish between correlation and causation, and to make valid inferences from known samples about the populations from which they were drawn. (For example, do the results of treating patients with two therapies justify the conclusion that one treatment is better than the other?) Biostatisticians regularly engage in interdisciplinary collaborations and advance their discipline through pursuit of methodological development of statistical methods for biomedical applications.
