Statisticians apply their knowledge of math to a variety of subjects. Typical areas include:

• Biology
• Economics
• Engineering
• Public health
• Marketing

One common technique that statisticians use is sampling. Sampling is a method of getting information about a group of people or things by surveying a small portion of the total.

Statisticians anaylze and interpret data to identify relationships and trends. They decide how to gather data based on project and client needs. In addition, they decide the type and size of the sample group.

They also develop questionnaires, polls, or report forms. They prepare instructions for workers who will collect and organize the data. They analyze and evaluate the data for the organization they work for. They evaluate the reliability of the data and the methods they have used.

Statisticians organize large amounts of data into a format that can be analyzed by computers. After data has been compiled and analyzed, statisticians present the results in the following formats:

• Presentations
• Graphics and charts
• Peer-reviewed papers
• Technical manuals

Some statisticians work in the manufacturing industry. They work on quality control and product improvement projects. For example, in a company that makes cars, a statistician might design an experiment to test how well engines perform in extreme weather.
