Biostatistician Job Descriptions, Average Salary, Interview Questions

What Does a Biostatistician Do?

Biostatisticians collect data from medical research and analyze it to draw conclusions or make predictions. They develop and execute research studies in collaboration with other statisticians and scientists and monitor clinical trials to ensure the integrity of the results. Biostatisticians must have exceptional written communications skills as they write research proposals and submit their findings to the scientific community. Some biostatisticians may also teach at universities while conducting their research, splitting time between the lab and the classroom. They are required to have an in-depth understanding of advanced statistical techniques, be familiar with analyzing clinical trials, and have excellent knowledge of epidemiology and statistics. The ability to plan, develop, and manage complex statistical computer databases is also important in this role.

Biostatisticians typically work in medical research, pharmaceuticals, public health, and clinical investigations. They should be familiar with specialized computer programs to analyze statistics and lab results. This role requires good collaboration skills as biostatisticians often interact with other scientists and researchers.

How to Hire a Biostatistician

When hiring a biostatistician, first consider the following:

  • Recruiting: Do you have the knowledge, tools, and resources to attract and screen candidates?
  • Complexity: Do you need a senior professional, or will mid or junior-level skills and experience suffice?
  • Duration: Is this a one-time project or an ongoing need?
  • Management: Do you have the time and expertise to direct the work effectively?
  • Urgency: How soon does the work need to be completed?
  • Headcount: Do you have the budget and approval for an internal employee, or should you consider alternate options?

Answering these questions will help determine the best course of action for your current hiring need. Fortunately, great options exist for every scenario. These are our recommendations:

1. Use 4 Corner Resources (or another professional recruiting firm)

The heavy lifting is done for you when working with a top-tier staffing company like 4 Corner Resources. We source, screen, recruit, and deliver only the most qualified candidate(s), saving you significant time and effort throughout the hiring process while you remain focused on your core business.

  • You need to fill the position quickly
  • You want access to a vast talent pool of high-quality, prescreened candidates
  • Your position is suited for temporary hiring services, contract staffing, or contract-to-hire recruiting, and you intend to direct the work activity.

2. Advertise your opening on a top job board

Your best option may be to advertise your opening on a proven job board. There are many widely used job sites out there that draw visits from qualified candidates. If you have someone internally who can dedicate the time and energy to sort through applications and screen individuals effectively, this can be a great choice. 

We recommend using a job board when:

  • Your internal recruiting team has the knowledge and experience to assess candidate qualifications
  • You are hiring a direct employee and have time to manage the entire recruiting effort 
  • You have a process for receiving, screening, and tracking all resumes and applications
  • You are prepared to respond to all applicants

There are many career sites out there. Here are the two we recommend for a biostatistician opening:

3. Leverage your internal resources

You can utilize your own website, social media, and employees to assist in your search for top candidates. 

A company website posting should be the first step in notifying prospective candidates that you are hiring. Social media can also be a powerful tool for spreading the word about your new opening. As far as exposure is concerned, this option can be as good as some job boards when you have a large enough following across various platforms, like LinkedIn, Instagram, Facebook, TikTok, and Twitter.

Current employees are every organization’s greatest asset. Encourage your internal team to promote job openings to their network by offering cash and other incentives.

We recommend these options when:

  • Your brand has great name recognition
  • You can consistently monitor and respond to candidate activity through your website and social media accounts
