Statisticians must figure out what factors, such as age of the television viewer, affected the results. Statisticians prepare reports that explain what they found. Most statisticians do not work in the field of statistics. Instead, they apply their skills to other areas of study. Common areas of work are economics, psychology, engineering, biology, and medicine.
Statisticians also work for manufacturers.
For these employers, statisticians develop quality control tests for products. For example, a statistician who works for a car manufacturer might design experiments on how weather affects engines. Statisticians try to find factors that would help performance. It sometimes is difficult to tell statisticians from specialists in other fields who use statistics. For example, a statistician who works with information about economic conditions may be called an economist.
