Today Statistics is an extremely effective and necessary tool in essentially all areas of science and industry.
Statistics is concerned with drawing conclusions and making decisions from empirical data.
Mathematical modeling plays an important role in statistics, with a special role for probability theory, which is often used to describe the variations in observed data and as a basis for making inferences from them. Modern Statistics covers a wide range of disciplines from the theoretical development of complex statistical and stochastic models to the most advanced applications of statistical methods in engineering, industry, medicine, biology, economics, social sciences and other fields. Typical problems range from efforts to identify risk factors for heart disease to design and analysis of an experiment to improve a production process to testing the effect of a new instructional program to estimating indices for tracking the economy. There is a strong interplay in statistics between theory and practice and many important ideas arose from the need to solve real problems. Statistical methods are needed in virtually all branches of science and technology and one of the exciting and enjoyable aspects of statistics is the opportunity to collaborate with colleagues from many different areas.
