What is the job of a Statistician?



The word statistician is a broad term that refers to professionals engaged in theoretical or applied statistics. They analyze various data to improve the knowledge of private or public sector experts or companies. Their work depends on their ability to provide reliable data using appropriate and up-to-date methods. Statisticians can help design research experiments, organize numerical data from censuses and clinical trials. They also perform various mathematical functions to analyze information.

For example, a statistician may need to obtain accurate data through other methods, such as management, conducting surveys, reviewing existing records, or interviews.


The responsibilities of statisticians include the following;

  1. Use statistical theory to collect, organize, interpret and summarize numerical data to provide helpful information;
  2. New mathematical theories can be developed;
  3. Can specialize in biostatistics, agricultural statistics, business statistics, economic statistics,r other fields.

Career Path

They have five vital career directions to choose from:

  • Analysis managers
  • Senior data analysts
  • Biostatisticians
  • Data scientists, and
  • Statistical mathematicians

Taking analysis manager as an example, it is divided into five small career directions, namely: analysis director, data scientist, senior manager (business analysis), business insight, and analysis manager.

In most cases, the further professional development of a statistician is to become a biostatistician or a mathematical statistician. The average annual income of biostatisticians is $5,000 more than that of senior statisticians, and the average yearly income of mathematical statisticians is $1,000 more than that of senior statisticians.

Sometimes they may become senior statisticians with an average annual income of $100,000, but this is not very common.

Common Skills of Statisticians

They need to use multiple skills in their work. People who have studied data analysis are often proficient in data modeling. Most notably, improving their skills in machine learning, Python, data modeling, and data mining/data warehousing may allow them to earn a salary that is 8% to 17% higher than the average salary.

Educational Requirements

To become a statistician, you must acquire at least a master’s degree. However, with a bachelor’s degree, you can apply for certain positions. Students focusing on statistics may also take courses in a related field, such as computer science, life sciences, or physical sciences. These courses can help students prepare for jobs outside of the statistics field. For example, biology, chemistry, and health sciences classes are helpful for people who work with pharmaceutical or agricultural products. Physics is useful for statisticians who work in manufacturing on quality.


The salary of a statistician is positively correlated with the level of experience. A statistician makes an average of $92,270 a year. The range is between $52,700 and $150,840.

According to the analysis of 463 salary data provided by anonymous users, the average salary (including tips, bonuses,s, and overtime) of a junior statistician with less than five (5) years of experience can reach a total of 66,000 US dollars. Based on the analysis of salary data of 152 employees, a statistician with 5 to 10 years of work experience can earn an average annual salary of US$95,000.

Based on the analysis of salary data of 78 employees, a statistician with 10 to 20 years of work experience has an average annual salary of US$110,000. According to 31 salary data analysis, a statistician with more than 20 years of work experience has an average annual salary of US$130,000.

Statisticians in which region earn the most?

Geographical factors have a great influence on the wages of practitioners in this field. Washington is one of the highest-paid places for statisticians, and it offers salaries 20% higher than the national average! The earnings of statisticians in Seattle, Dallas, Phoenix, and Philadelphia are also high, exceeding the national average by 15%, 14%, 11%, and 9%, respectively, while those in Indianapolis, Pittsburgh, and St. Louis have relatively low salaries, which are respectively 22%, 11,% and 10% lower than the national average.


Employment growth for statisticians will result from the more widespread use of statistical analysis to inform business, healthcare, and policy decisions. Businesses use statistical analysis to make informed decisions about everything from advertising to manufacturing. The amount of digitally stored data will increase over the next decade as more people and companies conduct business online and use social media, smartphones, and other mobile devices.
