Mathematicians and statisticians collect, analyze and interpret data. They identify trends and relationships in data, design processes for data collection, communicate findings to stakeholders, advise organizational and business strategy and assist in decision making.
Statisticians often perform the following duties:
- Analyze and interpret statistical data to identify significant differences in relationships among sources of information.
- Identify relationships and trends in data, as well as any factors that could affect the results of research.
- Determine whether statistical methods are appropriate, based on user needs or research questions of interest.
- Prepare data for processing by organizing information, checking for inaccuracies, and adjusting and weighting the raw data.
- Present statistical and nonstatistical results, using charts, bullets, and graphs, in meetings or conferences to audiences such as clients, peers, and students.
How to become a statistician
Statisticians typically need a master’s degree but some entry-level positions may accept candidates with a bachelor’s degree.
Most statisticians have degrees in mathematics, economics, computer science, or another quantitative field. A degree in statistics typically includes courses in linear algebra, calculus, experimental design, survey methodology, probability, and statistical theory.
Many colleges and universities advise statistics students to take courses in a related field, such as computer science, engineering, or physics. These courses can help prepare students to work in a variety of industries. Coursework in engineering or physical science, for example, may be useful for mathematicians or statisticians working in manufacturing on quality or productivity improvement. A background in biology, chemistry, or health sciences is useful for work testing pharmaceutical or agricultural products.
Important Skills and Abilities:
- Mathematics — Using mathematics to solve problems.
- Critical Thinking — Using logic and reasoning to identify the strengths and weaknesses of alternative solutions, conclusions or approaches to problems.
- Reading Comprehension — Understanding written sentences and paragraphs in work related documents.
- Active Listening — Giving full attention to what other people are saying, taking time to understand the points being made, asking questions as appropriate, and not interrupting at inappropriate times.
- Complex Problem Solving — Identifying complex problems and reviewing related information to develop and evaluate options and implement solutions.
- Mathematical Reasoning— The ability to choose the right mathematical methods or formulas to solve a problem.
- Number Facility— The ability to add, subtract, multiply, or divide quickly and correctly.
- Inductive Reasoning— The ability to combine pieces of information to form general rules or conclusions (includes finding a relationship among seemingly unrelated events).
- Deductive Reasoning— The ability to apply general rules to specific problems to produce answers that make sense.
ASA. The American Statistical Association https://www.amstat.org/
The American Statistical Association is the world’s largest community of statisticians, the “Big Tent for Statistics.” It is the second-oldest, continuously operating professional association in the country. Since it was founded in Boston in 1839, the ASA has supported excellence in the development, application, and dissemination of statistical science through meetings, publications, membership services, education, accreditation, and advocacy.
IMSTAT. The Institute of Mathematical Statistics https://www.imstat.org/
The Institute of Mathematical Statistics fosters the development and dissemination of the theory and applications of statistics and probability. https://www.imstat.org/ The IMS Career Center has a robust job resource center https://jobs.imstat.org/jobseeker/resources/ and connects employers with professionals. https://jobs.imstat.org/
ISI. International Statistics Institute. https://isi-web.org/index.php
The ISI mission is to lead, support and promote the understanding, development and good practice of statistics worldwide, by providing the core global network for statistics. The ISI has members from over 100 countries and its work and influence within the international statistical community are supported by standing and operational committees, special interest groups and regional networks.
The World of Statistics https://www.worldofstatistics.org/
The World of Statistics is a global network of nearly 2,360 organizations worldwide committed to increasing public awareness of the power and impact of statistics on all aspects of) society, nurturing statistics as a profession, especially among young people (https://www.worldofstatistics.org/how-to-become-a-statistician/), and promoting creativity and development in the sciences of probability and statistics. The World of Statistics website promotes these goals by providing regular blogs on applications of statistics that are bettering our lives, information about the many interesting and rewarding careers in statistics, and up-to-date information on statistically related events and activities worldwide.
If you like working with numbers and want to work in healthcare, you might want to be a biostatistician. Biostatisticians apply statistics to medical and public-health research. Almost daily, the media report new research findings related to human health. Health-related findings, or others concerning healthcare costs and quality, are usually based on the work of biostatisticians.
Biostatisticians often perform the following duties:
- Write research proposals or grant applications for submission to external bodies.
- Design statistical studies, decide how to gather data, and analyze the data, often in conjunction with physicians, health policy analysts, life scientists or other professionals.
- Analyze clinical or survey data, using statistical approaches such as longitudinal analysis, mixed-effect modeling, logistic regression analyses, and model-building techniques.
- Must be able to adapt when projects don’t turn out as planned or take longer than expected to complete.
- Develop or use mathematical models to track changes in biological phenomena, such as the spread of infectious diseases.
- Prepare tables and graphs to present clinical data or results.
