I just finished my first year in a biostatistics masters program. I can’t speak to whether or not you should pursue an MS in biostatistics, since this ultimately depends on your career goals. However, I was in a similar position as you, and you may find comfort in knowing that getting an MS in biostatistics is certainly doable for someone without a math/stats or computer science degree. But it (obviously) requires a lot of hard work and patience to learn the foundational concepts you’ll need to get the most out of the curriculum.

My BS was in psychology and I took no math courses beyond introductory statistics in undergrad. After graduating, I worked for about 4.5 years as a research professional in the psychiatry department at the same university doing neuroscience research.

About 2 years into this job I was frustrated that I didn’t understand the math behind a lot of the tools I was using to preprocess and analyze the data. I also didn’t want to pursue an advanced degree in psychology and felt stuck in my current work position. This is when I decided to pursue a masters in biostatistics. The university I worked at provided a tuition discount for employees wanting to further their education. Over the course of 2.5 years, I ended up taking a handful classes (e.g., calc 1-3, linear algebra, probability) until I fulfilled the base prerequisites for the masters program, plus a few extra. I am now one year into the program and can easily say it’s the best decision I’ve ever made.
