Biostatistician Definition

What is a Biostatistician?

Biostatisticians are math and statistics experts who gather data on medicine, public health, and other related fields like biology and immunology. Biostatisticians design, conduct, and oversee critical data-collection efforts, and use statistical methods to improve organizational procedures, inform public health policy decisions, and facilitate advances in medical technology.

Biostatistician: Job Description

What Does a Biostatistician Do?

Biostatisticians have different responsibilities depending on their specific role, but in general, they’re responsible for collecting and analyzing health data to enable better-informed decision-making for the organization that employs them. That may mean designing research studies or clinical trials, analyzing hospital patient data, or interpreting data gathered from outside sources to deliver meaningful conclusions (with the numbers to back them up). In addition, Biostatisticians frequently prepare reports that distill their findings into a more easily digestible format and sometimes write proposals to secure grants or other funding for future research.

Some of the day-to-day responsibilities of biostatisticians include:

  • Designing research studies or clinical trials to address specific topics
  • Developing effective and ethical data-collection methodologies
  • Ensuring sufficient sample sizes and overseeing the overall quality of data
  • Analyzing and interpreting data to form conclusions
  • Reporting their findings to companies, government organizations, or academic colleagues
  • Writing proposals or grant applications to secure necessary funding

Biostatistician Skills

You’ll definitely need solid math skills to become a biostatistician, as crunching numbers will be one of the main focuses of your job. Attention to detail is also paramount for biostatisticians, who must work with precision and vigilance to ensure they’re drawing accurate conclusions from the data they gather. Writing and communication skills are also important for a career as a biostatistician. Nobody will expect you to become an award-winning poet, however, the ability to clearly communicate your conclusions (and their potential implications) will make you a valuable contributor to any project.

Where Do Biostatisticians Work?

Biostatisticians perform vital analytical work for many different types of organizations, from pharmaceutical and medical manufacturers to hospital systems and government health organizations. As a biostatistician, you can expect to spend the bulk of your time in an office setting, though some roles will also spend time in laboratory or clinical environments. Most biostatisticians tend to work full-time, 40-hour workweeks, and business hours usually are fairly standard. Work-related travel is usually rare, so if you prefer to put your head down and get your work done, becoming a biostatistician could be a great fit!

Biostatistician Schooling & Certification

How Long Does It Take to Become a Biostatistician?

What Degree Do You Need to Be a Biostatistician?

Biostatisticians must have an advanced knowledge of mathematical and statistical methods, which means earning at least a bachelor’s degree is mandatory for this career field. While traditional bachelor’s degree programs require a full four years in school, some accelerated degree programs can be completed in just two and a half years. Some biostatisticians earn their bachelor’s degrees in math, science, or statistics, but that’s not necessarily the only path to a career as a biostatistician. Healthcare-focused programs or even degrees in other subjects like social sciences or humanities can also prepare you for a career in biostatistics, especially if you plan to pursue a postsecondary degree.

The highest-paid biostatisticians also frequently earn a Master of Public Health (MPH) degree, which involves advanced training in biostatistics and several other aspects of public health. Many master’s degree programs require another two to three years in school, but just like your bachelor’s degree, you can finish your MPH degree much faster with an accelerated degree program. Some MPH programs can even be completed entirely online in as few as 63 weeks!

Like any other long-term goal, becoming a biostatistician can be broken down into a series of smaller steps, which can keep you on track and make the final outcome feel much more attainable.

Student completing the admissions process

Here’s a step-by-step guide to the education, experience, and certifications you’ll need to become a biostatistician:

1. Enroll in a Healthcare-Focused Bachelor’s Degree Program

The first step in your biostatistician training is enrolling in a bachelor’s degree program from an accredited college or university. For a future career as a biostatistician, you may want to consider a B.S. program focused on math or statistics, or on health-related fields like a Bachelor of Science in Health & Wellness or a Bachelor of Science in Healthcare Administration. Earning your bachelor’s degree will certainly be a challenge at times, but with dedication and hard work, just about anyone can make it happen. For example, to enroll in any of the healthcare bachelor’s degree programs at Brookline College, all you’ll need is a high school diploma or GED, plus a passing score on a Scholastic Level Exam and a computer literacy exam.

2. Earn Your Bachelor of Science Degree

The best biostatisticians combine advanced statistical knowledge with a well-rounded understanding of human health issues. That means earning a healthcare-focused bachelor’s degree can give you a significant head start over other degree programs as you work toward a career as a biostatistician.

Like any bachelor’s degree program, you should expect to study a number of general-education subjects like math, literature, statistics, psychology, and communications. While math and statistics courses may seem the most relevant for future biostatisticians, there’s a reason all these classes are part of any bachelor’s degree program. They’ll make you a more well-rounded person and professional and help you discover new interests and talents.

Of course, there’s more to becoming a biostatistician than just crunching numbers. You’ll also need plenty of contextual knowledge about human health and behavior, as well as how healthcare facilities and programs work in the real world. Any bachelor’s degree program with a concentration in healthcare will likely include courses in everything from kinesiology to psychology to courses focused on health education and healthcare administration. Other classes will teach you leadership and management principles and how to use data and statistics in the context of public health issues. All these skills are vital for biostatisticians, who must be effective communicators and strategists as well as competent researchers and data analysts.

3. Earn Your Master of Public Health (MPH) Degree

While earning a bachelor’s degree will make it possible to land some entry-level public health jobs, earning a Master of Public Health (MPH) degree is how you’ll really stand out as a biostatistician. This is because most MPH programs include advanced training in biostatistics and help you polish the leadership, analytical, and communication skills you’ll need to fulfill your career potential.

In addition to helping you master biostatistics, your public health master’s program will include courses covering subjects like epidemiology and environmental and occupational health. You’ll also take classes that dive deeper into measuring clinical effectiveness and how to analyze and improve public health systems and policies.

At the end of your MPH program, you’ll need to complete a capstone course where you’ll apply the statistical methods you’ve learned to some aspect of public health. This capstone will demonstrate your ability to interpret data and draw meaningful conclusions that will stand up to scrutiny. For future biostatisticians, this should feel like your bread and butter!
