This site explores Statistics as a branch of applied mathematics with a focus on business applications. It offers a wide range of practical tools for processing random data.
Statistics provides methods and techniques for collection, presentation, interpretation and analysis of random data. It assists us in decision making and operation control under uncertain conditions.
Statistics is a playground for Probability. It helps us better understand probabilistic aspects (constraints, requirements, implications, etc.) of our uncertain environment. Virtually all statistical reasoning is based on probabilistic measures and criteria.
