Statistics is the science of learning from data.
Statisticians are interested in the collection and interpretation of information. Information arises in many settings, and statisticians have the opportunity to work on many different kinds of projects. Statistical models and methods are essential in all types of scientific research. For example, biomedical researchers use clinical trials to investigate the efficacy of new treatments, agricultural scientists use field experiments to evaluate irrigation methods, ecologists use complex instruments to measure the quality of water, and behavioral scientists use psychological tests to study how we reach the everyday decisions in our lives. They use statistics to enhance the validity of their inferences.
