Career in Statistics
A student wrote to me: “I like mathematics and have high grades in all math classes. I have read your blog about careers in mathematics and interested in study statistics in the U.S., but I could not find information about this field. Can you give me some advice as well as the job market? Thank you.”
Answer: Statistics is the application of mathematical principles to the collection, analysis, and presentation of numerical data. Statisticians apply their knowledge and skills to the design of surveys and experiments to collect, process, analyze and interpret the results to others to make decisions. Statisticians work many areas from biology, economics, engineering, medicine, public health, marketing, education, and even sports. Many economic, business and military decisions cannot be made without data and statistical techniques. In business and industry, statisticians play a major role in quality control and in product development. For example, in an automobile company, statisticians might perform experiments to determine the failure time of engines. In a pharmaceutical company, statisticians might develop and evaluate the results of experiments to develop new drugs.
Many U.S. universities provide degrees in statistics (BS, MS, and Ph.D.). The training program requires several classes in statistics and mathematics (Advanced Mathematics, Calculus, Probability, Forecasting, Differential Equations, Vector analysis, etc.) Because computers are often used for statistical applications, many programs also require students to take several computer courses. Beside technical courses, students also need good soft-skills, especially communications skills because statisticians often need to explain technical matters to persons without mathematics knowledge.
Although employment does exist for graduates with a Bachelor's degree, most jobs require a Master's degree or even a Doctorate degree in statistics or mathematics. Research and university positions often require a Ph.D., in statistics. The demand for statistician is projected to grow 13% in the next ten year because the use of statistics is widespread and growing. Statisticians help decision-making in both private industry and government. Technological advances also increase demand for statisticians because computer allows them to analyze more data quickly to help managers making the right decision to take advantage of the new opportunity that would not have been done in the past.
