Biostatistics Degrees and Master’s in Biostatistics Programs

What is Biostatistics?

What is biostatistics exactly? Biostatistics uses statistical processes and methods to analyze and interpret quantifiable data relating to living things. It combines math, statistics and biology. When a medical study cites data or statistics, a biostatistician was likely on the research team. Biostatistics is important because it helps to make sense of data to improve public health.

What is Biostatistics in Public Health?

Biostatistics in public health is often used to assess biological and environmental risk factors for disease or determine the efficacy of an intervention. It often helps to distinguish between correlation and causation in studies. For example, Did this environmental factor actually cause this health event? In medicine and public health, differentiating between correlation and causation is critical.

Biostatisticians can help interpret data, explaining if an intervention worked or how it affected study participants. They can also help design a study by determining data needs.

Biostatistics vs Statistics Degrees

Biostatistics and statistics both involve data collection and interpretation. Statistics is a broad approach to data analysis and collection. The key distinction is that biostatistics uses statistical methods to answer questions pertaining to topics in biology.

Coursework for these degrees may overlap, but typically, statistics is more theoretical. Biostatistics classes will use statistical methods for real-world applications, particularly in medicine. For those who want to do research, a degree in biostatistics will be beneficial. However, statisticians can also be hired to conduct research.

Bachelor’s Degree in Biostatistics

A solid foundation in mathematics is highly recommended for those seeking a Bachelor of Science (BS) in biostatistics. Prerequisite classes may include courses in math and biology and possibly ecology, epidemiology, chemistry or other science courses. Classes that focus on statistical packages, such as SPSS or EpiInfo, could be considered helpful as well.

Courses that improve communication skills are also recommended. This is because biostatisticians have to interpret data and communicate research findings to other public health professionals and stakeholders.

Many schools may not offer a bachelor’s degree in biostatistics. A BS in statistics or mathematics are relevant degrees for those interested in biostatistics. They will still provide the foundational skills needed to apply to master’s programs. Electives may help students gain a better understanding of biostatistics and its integral relationship to public health.

Curriculum for a Bachelor’s Degree in Biostatistics

Schools that do offer bachelor’s degrees in biostatistics will have required courses that focus on learning statistical methods. While most coursework will be in statistics, students will also need to take biology courses. Internships may be required, depending on the college or university. Students pursuing this degree can benefit from research-focused internships.

Examples of undergraduate courses in biostatistics include:

Intermediate Statistics: Design and Analysis
This course will build on information from introductory statistics courses. This covers two-sample t-tests, analysis of variance, contingency tables analysis, and Screening and Simpson’s paradox (Yule-Simpson effect). Students will learn issues in experimental and nonexperimental design and sampling plans. This course will use a statistical computer package.

Basic Elements of Probability and Statistical Inference

Master’s Degree in Biostatistics

Those who want to continue their education and advance their career can earn a Master of Science in biostatistics or Master of Public Health (MPH) with biostatistics as a concentration. Master’s programs educate students in statistical theory, bioinformatics and biostatistical methods, planning studies, conducting analysis, interpretation of analysis and writing reports.

Admissions departments will often look for relevant undergraduate coursework in probability, statistics, numerical analysis, biology, genetics and bioinformatics. Working knowledge of a programming language, calculus and statistical computing software could also be required for admission.

At the end of an MPH in biostatistics program, a capstone course and practicum are required. The capstone consists of a paper and presentation that demonstrates a student’s skills and competencies related to a current public health problem. The practicum is a valuable firsthand experience that may help students apply to jobs and advance their careers. The practicum is an opportunity to conduct research in a real-world setting.

Research is a key component of biostatistics and many departments encourage their students to work or volunteer for a research project.

Coursework Example of MPH in Biostatistics

MPH Biostatistics courses usually require about 42 credits and take 18 to 24 months to complete. The courses are made up of a combination of required core subjects (approximately 16 credits), concentration requirements (approx. 12-21 credits), electives (approx. 6-9 credits), an Applied Learning Experience (ALE) and a capstone project (approx. 6-9 credits), sometimes a combination depending on the school. While some fundamental courses are required to take prior to some concentration courses, students are usually given some freedom to decide the sequence of certain courses to take. MS in Biostatistics programs may require slightly fewer credits (32-36 credits in total).

Some required core subjects may include courses: foundations of public health, budgeting and management, health systems, regulations and policies, public health assessment, principles of biostatistics and more. Some of them may be very similar to the core requirements of other specializations of online MPH programs.

Concentration requirements for the MPH in Biostatistics may include: intermediate biostatistics: regression models, survey research methods and data management, public health practice epidemiology, analytical workflow management

In addition to the biostatistics core subjects, there are elective credits that are selected in consultation with a student’s academic adviser. Some elective courses may include qualitative methods and analysis, environmental epidemiology, analysis of multilevel and longitudinal data and GIS/spatial epidemiology.
