What Exactly is “Biostatistics”?

what is biostatistics

According to the Oxford Journal of Life Sciences, Mathematics and Physical Science, Biostatistics is a field whose primary goal is “to advance statistical science and its application to problems of human health and disease, with the ultimate goal of advancing the public’s health”.

What is Biostatistics?

Biostatistics (or biometry) deals with the statistical processes and methods applied to the analysis of biological phenomena. The science of biostatistics incorporates the design of biological experiments and interpreting the collection, summarization, and analysis of data from those experiments.

What Biostatisticians Do

Biostatisticians have one of the five major roles in public health practice. It’s their job to conduct quantitative research to identify health risks. They’re biomedical researchers who focus on solving community-wide health problems. Biostatisticians follow the scientific method to test their hypotheses with empirical research. Biostatisticians run clinical trials, surveys, lab experiments, focus groups, field observations, and case studies. Compiling and analyzing the data comes next to draw proven conclusions. Biostatisticians use digital software, such as SPSS and SAS, to organize their findings. Biostatisticians then share their statistically significant findings. They might write a journal article, publish a book, give a presentation, or teach a university class. Biostatisticians spread the word to help improve health outcomes. Arming people and public health workers with disease prevention tools is their mission.

Examples of Biostatistical Projects

What is biostatisticsBiostatisticians undertake various clinical research topics that affect public health. They often focus on a target population, such as elderly adults, infants, or cancer patients. Others take a big-picture look at health concerns like obesity, diabetes, opioid addiction, and smoking. Biostatisticians usually must write research proposals with detailed study designs to apply for grants. Proposed projects on pressing, life-altering health issues are the most funded. For example, a biostatistician might study birth defects caused by selective serotonin reuptake inhibitors. Biostatisticians could test how exercise correlates to hypokinetic diseases. A biostatistician may investigate the harm of environmental air pollution on people’s lungs. Biostatisticians can determine the effectiveness of light therapy for patients with dementia. Virtually any health-related subject is in a biostatistician’s wheelhouse for transformative research.

Where Biostatisticians Do Research

Biostatisticians are commonly employed by local, state, and regional health departments. At the federal level, biostatisticians work for divisions in the Department of Health and Human Services. For instance, biostatisticians can aid epidemiologists in research at the Centers for Disease Control and Prevention. Many are employed by public or private nonprofit and for-profit hospitals. Medical facilities currently posting jobs for biostatisticians include NYU Langone Health, Christiana Care, Fox Chase Cancer Center, the Cleveland Clinic, and the City of Hope. Pharmaceutical companies, such as Pfizer, AstraZeneca, Merck, and Bristol Myers Squibb, hire biostatisticians for clinical trials. Universities employ biostatisticians in their public health departments to conduct research and teach students. Biomedical research and development corporations like Novartis or Leidos also have biostatisticians on the payroll.

Requirements to Become a Biostatistician

Like other mathematicians, biostatisticians need a master’s degree or higher to practice. A biostatistician’s journey starts with four years, or 120 credits, of baccalaureate education after high school. Declaring bachelor’s majors in statistics, math, public health, psychology, and even computer science can help. As an undergrad, take at least one statistics and research methods course. Applying for graduate school comes next. Most graduate programs for biostatisticians require taking the Graduate Record Exam (GRE). Once admitted, future biostatisticians must finish 30+ master’s credits and thesis research. Master of Public Health concentrations also typically entail 240 or more hours of fieldwork. Individuals who already have a master’s degree could add a certificate in biostatistics instead. Employers, especially colleges, may prefer hiring biostatisticians with a Doctor of Philosophy (Ph.D.) or Doctor of Public Health (Dr.PH).

Higher education isn’t the only requirement to become a biostatistician; experience matters too. Organizations look for biostatisticians with a clear understanding of scientific research. Internships, cooperative education, and capstone projects can build this knowledge. The American Statistical Association (ASA) keeps a running tally of available internships to peruse. Many biostatisticians have to work their way up from entry-level jobs. Future biostatisticians may work as data analysts to sharpen their numerical abilities. Individuals can start as research assistants to learn laboratory protocol firsthand. Young quantitative scientists might find principal investigators who will mentor them. Some biostatisticians migrate into the field from other “Big Data” careers. Filling a resume with STEM education and experience is the key to success.
