How is epidemiology different from biostatistics?

Epidemiologists typically focus on pathogens and epidemics; they are concerned with specific health-related events. Biostaticians, however, focus on broader biological issues, such as those related to genetics.

Why is epidemiology and biostatistics important?

Epidemiology and biostatistics are the cornerstone of public health and preventive medicine. These practices use mathematical, scientific, and social methods to monitor disease trends and provide intervention to prevent future disease.

What is biostatistics in public health?

Merriam-Webster’s defines biostatistics as the “statistical processes and methods applied to the collection, analysis, and interpretation of biological data and especially data relating to human biology, health, and medicine.” Public health officials, health care professionals, and the scientific community rely on …

What is biostatistics used for?

In essence, the goal of biostatistics is to disentangle the data received and make valid inferences that can be used to solve problems in public health. Biostatistics uses the application of statistical methods to conduct research in the areas of biology, public health, and medicine.
