Career: Statistician

 
A Day in the life of a Statistician

Statisticians collect data and analyze it, looking for patterns that explain behavior or describe the world as it is. A good statistician is involved in survey development and data collection from the beginning, ensuring the validity and usefulness of the data. Statisticians are employed by private and public concerns and apply their skills to specific industry issues, such as economic analysis, inventory control problems, health problems, and even television demographics. Statisticians must be familiar with valid scientific protocol and be able to quickly familiarize themselves with baselines and historical industry figures in order to structure an uncompromised analysis. Statisticians spend over half their day in front of a computer, setting up models, manipulating data, analyzing data, or writing reports. “You don’t just crunch numbers. You explain them,” wrote one veteran statistician, who said that writing skills are important for those hoping to advance in the field. They spend the rest of their day in meetings, in planning sessions, or on the telephone exchanging ideas with colleagues. Respondents said, “Statistics is a visual science. You have to be able to picture the data and how it fits in with other known data shapes. It is not a Ônumbers only’ job.” Most statisticians are applied statisticians, tailoring studies to real-life problems. It takes mathematical, visual, and practical skills to excel in this occupation as well as flexibility, curiosity, and a rigorous mind. Statisticians said the most difficult part of their job is explaining the implications of their studies to non-statisticians. Many said that statistics are best used as a starting point for investigation, not as a conclusion, and upper-level managers find this concept difficult to grasp. One wrote, “Statistics is a science of trends and probabilities, not certainties. We can tell what things happened, and suggest why they might have happened, but they’re only suggestions.” Many statisticians cited the support of the statistician community as important to their satisfaction in the field. Statisticians feel challenged, involved and invigorated by their work, and this is evidenced by the small number (under 11 percent) of statisticians who leave the field each year.

Paying Your Dues

There are strict academic requirements for becoming a statistician. Entry-level positions require a Bachelor’s degree in Mathematics or Statistics. Those who wish to rise in the profession should consider obtaining a Master’s degree or a Ph.D. Just under 100 universities offer graduate degrees in statistics. Suggested coursework includes mathematics (calculus and linear algebra), probability, logic, psychology, and computer science. Candidates who combine statistical skills with another major that reflects their professional direction-such as economics and econometrics, computer and material science, or biology-have a distinct competitive advantage when seeking employment. Membership in professional organizations is not required, but many choose to join the ones affiliated with their occupation, such as organizations for economists or manufacturers.

Associated Careers

With their strong mathematical aptitude, many careers are open to statisticians. Wall Street is the most common employer of mathematical statisticians who leave their field, followed closely by the government, which regularly hires statisticians as “area analysts”. A number become accountants, insurance analysts, and actuarial analysts when they want to improve their quality of life. A significant few enter computer science and become programmers and systems analysts.
