At a Glance
To become a biostatistician, you’ll need at least a master’s degree in biostatistics, statistics, or a related field. Most entry-level roles require graduate-level education, and senior or academic positions typically call for a doctoral degree. The Bureau of Labor Statistics reports a median annual wage of $103,300 for statisticians, with 8% job growth projected through 2034.
Most of the major clinical trials you’ve heard about (COVID-19 vaccines, cancer treatments, new drugs for chronic disease) had biostatisticians behind them. They designed the studies, defined the sample sizes, and determined whether the results were statistically meaningful or just noise. Rigorous statistical analysis is a core requirement of the regulatory review process. Without it, study findings can’t support approval decisions.
Biostatisticians collect and analyze data at the intersection of biology, medicine, and public health. They model how diseases spread, evaluate whether interventions work, and provide the quantitative backbone for evidence-based health policy. It’s a field where the math directly affects people’s health outcomes. If you’re still mapping the broader landscape, our guide to public health careers covers the full range of roles across the field.
What Biostatisticians Actually Do
The day-to-day work varies by employer and sector, but most biostatisticians share a core set of responsibilities. They design research studies and clinical trials, write statistical analysis plans, clean and analyze large datasets, and communicate findings to clinicians, public health officials, and policymakers who may not have a statistics background.
Key areas where biostatistics drives public health decisions include:
- Epidemiology: modeling disease transmission and population-level risk factors
- Clinical research: evaluating the efficacy and safety of new treatments
- Environmental health: identifying statistical links between exposures and health outcomes
- Health services research: measuring the effectiveness of care delivery systems
- Nutrition and public health programs: assessing interventions at scale
Proficiency in statistical software is a practical requirement. R and SAS are the most commonly listed tools in biostatistician job postings. Python is increasingly common, particularly in roles with a data science component. SPSS still appears in some academic and government settings.
The Education Path to Becoming a Biostatistician
There’s no single required credential or license for biostatisticians. Employers set their own education standards. That said, the field follows a well-established pattern: a quantitative bachelor’s degree to build the foundation, a master’s degree to qualify for professional roles, and a doctoral degree for academic or senior research positions.
Step 1: Earn a Relevant Bachelor’s Degree
Few undergraduate programs offer a degree specifically in biostatistics, so most future biostatisticians major in statistics, mathematics, public health, or a closely related quantitative field. What matters is building a strong foundation in calculus, linear algebra, probability theory, and statistical methods before graduate school. A minor or coursework in biology or a health-related discipline is a useful context, particularly if you know you want to work in medicine or epidemiology. Entry-level roles in the field (data analyst, research assistant, study coordinator) are often open to candidates with a bachelor’s degree, which can provide valuable experience before or alongside graduate education.
Step 2: Earn a Master’s Degree in Biostatistics or a Related Field
A master’s degree is the standard entry point for professional biostatistician roles. According to Lightcast job posting data compiled by Franklin University, a master’s degree appeared as the stated requirement in approximately 40% of biostatistician postings analyzed, more than any other degree level. The Bureau of Labor Statistics similarly reports that a master’s degree is the typical entry-level education for mathematicians and statisticians. Master of Science (MS) programs in biostatistics, statistics, or public health with a biostatistics concentration typically take two years and include graduate coursework in probability, regression analysis, survival analysis, longitudinal data methods, and statistical computing. Admission requirements commonly include prerequisite coursework in calculus and linear algebra. Many programs include an internship, practicum, or thesis component that provides hands-on research experience before graduation.
Step 3: Consider a Doctoral Degree for Senior and Academic Roles
A doctoral degree (typically a PhD in biostatistics or statistics) opens the door to the highest-level positions in the field: academic appointments, principal investigator roles on major research grants, leadership positions in pharmaceutical and federal agency research programs, and positions in advanced methodological research. According to the same Lightcast job posting data, a PhD or professional degree was listed as the requirement in approximately 30% of biostatistician postings. Doctoral programs generally take four to six years beyond a master’s degree and culminate in original dissertation research. Both the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) include doctoral-level biostatisticians and statisticians among their posted roles in research and fellowship programs.

Biostatistician Salary and Job Outlook
The Bureau of Labor Statistics (BLS) groups biostatisticians under mathematicians and statisticians for tracking purposes. As of May 2024, the median annual wage for this group was $103,300. Employment in the field is projected to grow 8% from 2024 to 2034, faster than the average for all occupations, driven by demand in healthcare, pharmaceutical research, and federal public health programs.
Salaries vary by sector and degree level. The BLS reports that federal government agencies and scientific research and development services are among the top-employing industries for this occupation, and compensation tends to reflect the advanced credentials and specialized expertise the work requires. Entry-level roles at the master’s level typically fall below the field median, while senior and doctoral-level positions often exceed it by a significant margin.
The BLS reports that most mathematicians and statisticians (the broader category that includes biostatisticians) work in the following sectors:
- Scientific research and development services
- Federal government agencies
- Management, scientific, and technical consulting
- General medical and surgical hospitals
- Computer systems design and related services
Certifications and Professional Organizations
There’s no required national or state-level license to work as a biostatistician, though individual employers and agencies may have their own certification preferences. Voluntary credentials exist and can strengthen a resume, particularly for candidates entering from adjacent fields.
The American Statistical Association (ASA) offers two voluntary credentials: the Graduate Statistician (GStat) designation for those who have earned a degree in statistics or a related field, and the Accredited Professional Statistician (PStat) designation for experienced practitioners with a graduate degree and demonstrated professional practice. Neither is a prerequisite for most positions, but both signal commitment to statistical rigor and professional standards.

Frequently Asked Questions
How long does it take to become a biostatistician?
Plan on a minimum of six years of post-secondary education: four years for a bachelor’s degree plus two years for a master’s. If you pursue a doctoral degree, add another four to six years. Some professionals enter the field at the master’s level directly after their undergraduate degree, while others work in adjacent roles first and complete graduate education later or part-time.
Can I become a biostatistician with just a bachelor’s degree?
A bachelor’s degree in statistics, math, or public health can get you into entry-level roles (research technician, data analyst, study coordinator), but the title of biostatistician and the responsibilities that come with it typically require a master’s degree. Employer requirements vary, but graduate-level education is the norm for independent analytical work in this field.
What’s the difference between a biostatistician and an epidemiologist?
Both fields work with health data, but their focus differs. Epidemiologists study the distribution and determinants of disease in populations (the “who, what, when, where, and why” of illness). Biostatisticians provide the quantitative methods that epidemiologists and other researchers use to analyze the data. In practice, the roles frequently overlap, and many professionals hold training in both. See our guide to careers in epidemiology if you’re weighing the two paths.
Is a license required to work as a biostatistician?
There’s no national or state-level licensing requirement for biostatisticians. Individual employers and agencies may have their own certification preferences, but most evaluate candidates primarily on degree credentials and relevant experience. Voluntary designations like the ASA’s Accredited Professional Statistician (PStat) exist for those who want a formal credential, but they’re not required for most roles.
What software do biostatisticians use?
R and SAS appear most frequently in biostatistician job postings, based on job market analyses of the field. Python is increasingly expected, particularly in roles with a data science or machine learning component. SPSS is still used in some academic and government settings. Familiarity with at least one of these (and ideally more) is a practical asset for most positions.
