Biostatistician At a Glance
A biostatistician is one of many roles that fall under the umbrella of public health. As with all public health roles, biostatistics is focused on large patient populations rather than on one patient at a time. Biostatisticians don’t work at bedsides or see patients in offices. Instead, they analyze medical data to look for answers to important questions and solutions to challenging health problems.
“There’s a quote I love that says, ‘Every dataset has a story,'” says Aracelis Torres, PhD, MPH, vice president of quantitative sciences at Verana Health and an adjunct professor at Columbia University Graduate School of Arts and Sciences. “There’s an element of storytelling to data analysis, and biostatisticians tell that story to answer questions like, ‘What journey did this data take? What is going to be done with it? How will physicians use this information to help patients?'”
Biostatisticians use data to figure out how well new medications are working, what course a newly discovered disease might take, or if new policies implemented by a hospital are effective. This career might be an ideal fit for you if you’re interested in problem solving and data analysis. Now is a great time to get started, because you’ll have a lot of opportunities over the next decade. The U.S. Bureau of Labor Statistics (BLS) predicts an impressive 33% growth in roles by 2030. Why such a huge number? Medical data is everywhere, and more is being generated every day. Biostatistician are needed to put it all together.
A career as a biostatistician might be for you if you’re interested in problem solving and data analysis.
“When we think about any single individual, there are many different ways they create data that is useful for healthcare,” Torres says. “Whether it’s having their vitals taken during a hospital stay, interacting with their physician during an exam and answering questions that get recorded in an EHR, or using a wearable technology device to track steps and heart rate, those pieces of data all come together through biostatisticians who glean meaningful insights to inform care.”
You’ll need to earn at least a master’s degree to take on most biostatistician roles, although a bachelor’s degree can get you started.
Steps to Becoming a Biostatistician
You’ll join a growing and fascinating field when you work as a biostatistician. To get started, you’ll need to complete your education and gain some experience. Steps to take in your career include:
Earn a bachelor’s degree in a related field.
You can’t earn a bachelor’s degree in biostatistics specifically, but you can study a related subject such as biology or statistics.
Gain some practical real-world experience.
It can help to gain some experience in the field. A role such as data analyst or research assistant can help you stand out when you apply to a master’s program.
Earn your master’s degree in public health or a related field.
You’ll need a master’s degree to pursue most biostatistician roles. You can earn your master’s degree in public health, biostatistics, or a closely related public health specialty such as epidemiology.
Consider pursuing a PhD.
A PhD can help you gain leadership and research roles in biostatistics. It’s a great degree path for people who want to plan and design their own research or who are interested in teaching.
What Do Biostatisticians Do?
Biostatisticians take on the responsibility of analyzing medical data to look for specific effects or properties. They play a vital role in healthcare without any patient interaction. This can make it a great fit for people who are drawn to the healthcare field but aren’t interested in the clinical aspects. You’ll need strong organizational, analytical, and communication skills to succeed in this role.
On the job, biostatisticians might study the data for patients who have all contracted a specific virus or bacteria to look for patterns. They might also analyze all the data coming back from the trial of a new prescription drug to evaluate how effective the drug is. Biostatisticians who work for environmental or government agencies might study the effects of an air pollutant or oil spill.
“Biostatisticians have to start from the lens of data empathy—taking time to understand where data is coming from and what processing has been done on the data before running analyses,” says Torres. “There may be aspects of where that data is coming from, who is generating it, and how it’s being generated that may play a role in what the analysis reveals.”
Once the data is analyzed, the biostatistician’s next step is to make their analysis understandable to the people who will be reading it.
“Biostatisticians weigh the pros and cons of different statistical techniques and the types of conclusions that can be made, and then ensure those conclusions are relevant to and understandable for a variety of audiences,” Torres says. “You can generate really fancy results, but if no one can understand what it means or what to do with them, there’s little to no impact.”
A Day in the Life of a Biostatistician
As is the case with many healthcare careers, it’s hard to predict a typical day. Even with a more office-based role such as biostatistician, your day will depend on the project you’re currently working on. Torres says that while your days can vary, you can count on interacting with data.
“There is rarely a typical day for a biostatistician, but a core component is some type of interface with datasets. This can mean sitting down at the computer to work on cleaning the data, preparing data for analysis, running an analysis on the dataset, or talking with other collaborators about study design and goals,” Torres says.
A master’s degree is considered the minimum for most biostatistician roles, although you might be able to find some jobs with a bachelor’s degree. Experience in the field can go a long way toward helping you achieve a biostatistician role.
“The degree choice for biostatistics depends on what you want to do in the field. There’s a benefit to having more structured learning, especially if you want to go into academia,” says Torres. “In that case, a master’s degree, a PhD, and even postdoctoral work would be useful. But real-world experience also provides a ton of value.”
A PhD can help you take on a leadership role and advance your career even further, Torres says. No matter what degree path you choose, it’s important to look at the connections your program has and the projects with which the facility have been involved.
Most biostatisticians hold a master’s degree, but many pursue a PhD, especially if they want to work in academia.
“Students considering their educational path to a career in biostatistics should understand what opportunities there are for internships, and the work that professors at an institution are involved in,” Torres says.
You won’t find any undergraduate programs specifically geared to biostatistics. However, you can earn a bachelor’s degree in a related field such as biology or statistics. It’s important to make sure your program covers biology, research, and statistics. You’ll need those courses to look for work and to apply to master’s programs. Some schools might offer elective biostatistics courses on the undergraduate level, and it’s a great idea to take those if you can.
A bachelor’s degree will allow you to take on jobs such as research associate or data analyst. You can use these roles to gain experience. Your experience and your bachelor’s degree might allow you to transition to a biostatistician role later. Even if your experience doesn’t translate to a biostatistician role, it can make your application to a master’s program stand out and might put you ahead of the curve when it comes to your coursework.
You’ll need a high school diploma, a solid GPA, and strong scores on your SAT or ACT to gain admission to a bachelor’s degree program. It can help to have taken math and science courses in high school.
There is no set bachelor’s degree in this field. It can help to take courses in statistics, probability, biology, data analysis, and research.

Biostatistician Job Growth
The role of data and technology is becoming increasingly important in all fields, including healthcare. Electronic records and digital data storage have become standard in healthcare in the past several years. In response, new roles to analyze this data are being created.
“In order to make sense of all this data that’s being collected on a daily basis, you need proper study design and proper methods to generate accurate conclusions from all that data,” says Torres. “The healthcare system needs professionals that can make sense of all the data with care and ensure proper interpretation. That’s where biostatisticians come in: to organize messy data and provide meaning and insight.”
