What Is a Biostatistician? 2025 Career Guide

Biostatisticians are data collectors and analysts who focus on biology for fields such as medicine, agriculture, and public health. Working at the intersection of health and data science, they are the wizards who produce and verify public health statistics.

Health care occupations could grow much faster than average from 2023 to 2033, with biostatisticians specifically expecting a growth rate of 11 percent [1, 2]. 

Biostatisticians do important work. What makes them unique are the complexities of the real-world problems they’re finding solutions for, such as the needs of an aging population and Alzheimer's disease treatment. Conducting rigorous analyses in a timely manner is urgent in order to save more lives. While most biostatistician jobs require a bachelor’s degree, many look for a master’s degree or higher.

Love working with health data and think it could be for you? Explore how to become a biostatistician.

What is a biostatistician?

Biostatisticians collect and analyze data for biology and public health purposes using math and statistics. Biostatisticians are critical to advancing groundbreaking research, from medicine to agriculture to public health.

If you’re a data-minded individual interested in a career in medicine or health but do not want to become a clinical doctor, nurse, or specialist, then this could be a good choice for you.

As a highly trained and educated biostatistician, you would analyze data and determine factors that impact the health and overall well-being of humans, animals, and ecology. Using this information, you and a team of researchers would deliver statistics, predictions, and studies on diseases and other health risks. You would gather data at every stage of an experiment or clinical trial to ensure thorough results from a big-picture perspective.

Where does a biostatistician work? 

Biostatisticians can work in a variety of settings on different types of research studies. 

Besides clinical settings, you can also choose to work in government or nonprofit organizations, in academia, in technology, or in a corporation. Biostatisticians sometimes work for pharmaceutical companies during their clinical studies to determine whether a drug is effective. You might do the same for a medical device company. You may work for a public health-focused non-profit to evaluate programs that inform policy making. In government-related roles, you would help shape public health and education policies. 

Biostatistician salary and job outlook

The salary of a biostatistician salary is above average. According to the US Bureau of Labor Statistics, mathematicians and statisticians earn a median annual salary of $104,860 [2]. As mentioned earlier, they can expect 11 percent job growth from now until 2033. Indeed lists an average salary of $103,871 [3]. 

What do biostatisticians do?

Biostatisticians typically work on a team of scientists and researchers to perform analyses, develop plans, and interpret results. 

Some job tasks and responsibilities of a biostatistician include:

• Develop methodologies for collecting data

• Design studies and clinical trials to solve a specific problem or question

• Collect and analyze large data sets

• Interpret results and disseminate findings with papers and presentations

• Prepare and write up reports that advise public health, education, or environmental policy

How to become a biostatistician 

Biostatisticians tend to be highly educated and trained in their fields, meaning that a master’s degree in statistics or public health is often required or recommended. Employers like to see that job candidates have experience with complex statistical analysis.

1. Begin biostatistician education requirements with a bachelor’s degree.

It is wise to consider a bachelor’s degree if you aspire to become a biostatistician. Most jobs require a master’s degree, and still, others will require a doctorate. Biostatisticians work with data to produce insights that can affect entire populations, so they must be experts at data analysis. 

If you’re considering the path to becoming a biostatistician, a bachelor’s degree in a quantitative major such as mathematics or statistics will set you up for success. However, don’t fret if you’ve already earned a bachelor’s degree in an unrelated field, such as humanities or social sciences. A master’s in mathematics, statistics, or another data-related field, plus a strong foundation of programming and data software management skills, can help you land a junior-level position as a biostatistician.

2. Gain the skills needed.

You’ll need technical and workplace skills for a role as a biostatistician. The specific skills and experience required may vary depending on the type of organization you aim to work for, so make sure to take a look at real job descriptions to understand what you’ll need to learn.

Technical skills:

• Programming languages such as R, Python, C or C++, JavaScript, MATLAB, and SQL

• Ability to manage and clean data using data analysis software SAS

• Strong knowledge of statistical theory, including longitudinal and complex data analysis 

• Expert experience in a specific area, such as epidemiology or public health

Workplace skills:

• Ability to multitask or contribute to multiple projects simultaneously

• Excellent communication and collaboration skills

• Strong academic-level writing skills

Biostatisticians are typically inquisitive and intellectual individuals who like to investigate a problem from beginning to end. They are logical, using methodical ways of collecting and analyzing data to inform public health decisions.

3. Go for a master’s degree.

If you’re serious about becoming a biostatistician, you might want to pursue a master’s degree in biostatistics, statistics, mathematics, or public health (with a focus on data and statistics). Approximately 58 percent of biostatisticians have a master’s degree, according to O*Net Online [4].

These days, with bachelor’s degrees being more ubiquitous, having a master’s degree for this type of specialized, technical job can help you stand out from the rest of the applicants. Some jobs even require a master’s degree or higher.

What degree do you need to be a biostatistician?

To become a biostatistician, you will likely need to earn a master’s degree. You can start with a bachelor’s degree in a related field like biology or statistics and focus on public health, biostatistics, epidemiology, or a related field for your master’s degree. 

Get started with biostatistics in public health on Coursera

As a biostatistician, you will help advance public health by conducting research that influences public policy. If you’re looking to further your skills in biostatistics, look no further than the Biostatistics in Public Health Specialization from Johns Hopkins University [5].

This Specialization is intended for public health and health care professionals, researchers, data analysts, and social workers who need a primer in the concepts of biostatistics. After taking this course, which requires four months or less, you may be ready to participate in a research team.
