Statisticians work with the theoretical and applied statistics in the private and public sectors. The core of their work is to measure, interpret, and describe the world. It is common to combine statistical knowledge with expertise in other subjects. Statisticians apply their knowledge to production, research, finances, medicine, insurance, and government. They often are employed to support managerial decisions. Typical work might involve developing a model and sampling plans, analyzing survey results, or contributing to agricultural or econometric forecasts.
