What Is a Statistician?

Find yourself wondering: what is a statistician, exactly? Statisticians use theories and tactics, like statistical modeling and data manipulation, to solve problems. They often work alongside stakeholders in other industries, from manufacturing to healthcare to agriculture, to assist with research and product development.

What Does a Statistician Do?

Statisticians design experiments, surveys and questionnaires to collect data. They may conduct surveys on the phone, through mail, online or in person. Conversely, they may use random sampling methods or poll entire populations of people. Once data is collected, statisticians analyze the results using statistical tools, algorithms, models and software. They look for trends within their data sets. Software is used to crunch large data sets and may even help find relationships or patterns. Some statisticians work on the development of new software to make crunching data easier.

Once they’ve completed their analysis, statisticians present their findings, accounting for anomalies or missing data. Presentations can be written, verbal or depicted with charts, tables or other visual elements. The Bureau of Labor and Statistics (BLS) offers more information about what a statistician does.

Depending on their level of experience, statisticians may be asked to:

  • Tackle data-related challenges assigned by management.
  • Decide upon an appropriate strategy to collect data.
  • Extract data from existing sources or instigate new procedures, including science experiments, opinion polls and more.
  • Design new statistical models and data collection tools if needed.
  • Provide strategic recommendations/predictions based on their statistical findings and highlight any data limitations.
  • Develop and maintain statistical tools, databases and programs.
  • Regularly monitor data quality.
  • Work closely with key team members and subject experts such as computer engineers, scientists and IT support personnel.

When answering the question, “What does a statistician do?” answers can vary based on specific job titles. Entry-level statistical analysts and assistants may be tasked with standard data analysis and supervised by higher-ups. Depending on the role and industry, experienced statisticians may be able to propose projects to management, develop new products and processes, oversee statistical teams and work on their own research.

Degree and Skills for Statisticians

From statistical modeling to critical thinking, statisticians employ and leverage a combination of soft skills and technical know-how to successfully carry out daily tasks. Statistician skills may overlap with those used in related career fields like data science and can be developed on the job as well as in a degree program.

Before entering the field, statisticians are trained to:

  • Identify the relevance of data.
  • Determine whether the underlying model assumptions are valid for the data at hand.
  • Prepare data for processing by adjusting and weighting the raw data, organizing information and checking for inaccuracies.
  • Interpret and communicate the results of a statistical analysis so that diverse audiences, including those employed in other fields, can understand the findings.

As you prepare to enter the field, think through what competencies and experiences might help you stand out in the job market and do your work effectively.

Mikhail Popov, a data analyst at the Wikimedia Foundation (WMF), breaks down what it means to be a statistician in an interview with Master’s in Data Science:

“The best statisticians don’t just throw their data into a black box (e.g., neural network) and rely on machine learning algorithms to do their work for them. Instead, they develop an understanding and intuition for the data they’re analyzing. The best statisticians are also great communicators. They can talk to their clients and collaborators through all the stages of an experiment or study. Those people may not be as well-versed in statistics but are usually experts in the subject matter, so it is crucial to work with them in unison. The best statisticians poke and prod at assumptions and aren’t afraid of being wrong. To see what I mean, play around with this interactive puzzle from The New York Times.”

What Kind of Degree Can I Pursue?

At minimum, statisticians will need a bachelor’s degree in statistics, applied math, computer science or a related field. Since you will be working with complex statistical software programs, a healthy balance between math and IT courses is recommended.

You may want to plan for a graduate degree. Certain companies looking to hire a statistician might prefer applicants to hold a master’s degree in applied statistics or math. They may also look for candidates with a background in a specific industry like finance, biochemistry or computer engineering.

What Kind of Skills Will I Need?

Technical Skills

Some common technical skills include:

  • Statistics (e.g. hypothesis testing and summary statistics)
  • Math (e.g., linear algebra, calculus and probability)
  • Machine learning tools and techniques
  • Software engineering skills (e.g. distributed computing, algorithms and data structures)
  • Data mining
  • Data cleaning and munging
  • Data visualization and reporting techniques
  • Unstructured data techniques
  • R and/or SAS languages
  • SQL databases and database querying languages
  • Programming languages such as PythonC/C++Java and Perl
  • Big data platforms like Hadoop, Hive and Pig
  • Cloud tools like Amazon S3

You’ll notice that some of these skills are also relevant to data science roles. Advanced programming skills may help prepare you for “hybrid” data science/statistician careers.

Which Skills or Programming Languages Do Statisticians Most Frequently Use in Their Work and Why?

Statisticians can expect to use multiple skills and tools at any given time in their careers. Popov provides some insight:

“The primary language/environment I work in is R. We’re also huge fans of RStudio’s Shiny (a web application framework for R) and use it for our dashboards to give the teams easy access to daily metrics and KPIs. My enthusiasm for R is no secret as I am a co-host and producer of the R Talk podcast. A lot of my work at NRP and a good chunk of my work at WMF also requires me to write file/text processing pipelines, so scripting is key to my work.

“Data visualization is a tremendously useful skill to learn and maintain. The best plot tells a story and guides the viewer/reader to a conclusion that otherwise takes at least one paragraph to reach with text. And I want to emphasize how important it is to be able to interpret results to non-statisticians. Telling a biologist what the hazard ratio is from your survival analysis is useless if you don’t interpret it. … raw parameter estimates are useless without an accessible narrative (and an accompanying data visualization).”

Soft Skills

Some common soft skills that may be helpful for statisticians include:

  • Analytical Problem-Solving. This type of skill involves identifying complex challenges and employing the right mathematical approach/methods to make the maximum use of time and human resources.
  • Logic and Reasoning.Through logic and reasoning, statisticians can assess the strengths and weaknesses of data and statistical methods. These skills also allow them to develop an understanding of the implications of new developments in technology and data mining.
  • Effective Communication. With strong communication skills, a statistician is able to explain their mathematical techniques and discoveries to technical and non-technical audiences.
  • Industry Knowledge. As a statistician, it can be useful to have an understanding of how your chosen industry functions and how data is collected, analyzed and utilized.

Data analyst Mikhail Popov shares the following insights about his profession and the field as a whole:

As a statistician, you will likely be asked to provide your expertise to teams working in a wide variety of fields and subfields, so you will get to become a mini-expert in each problem you’re involved in. You engage the creative, analytical and social parts of your brain simultaneously on a daily basis. You translate boring numbers into interesting stories. You quantify uncertainty and when you find patterns and relationships, you are able to say, “This is real, this isn’t just random noise.” Human beings are super good at seeing patterns where there are none, and your role is to guard leaders and decision-makers against that.

Nobody knows what exactly you do (not their fault). The most popular response you’ll hear is, “Ugh, I hated the stats course I had to take in college.” Your peers in computer science are constantly inventing methods that have already been invented and published by your fellow statisticians 50 years ago.
