Introduction to Mathematical Statistics
Mathematical statistics is the application of mathematical principles to the collection, analysis, and interpretation of data. It provides a framework for making inferences about a population based on a sample, and for testing hypotheses about the relationships between variables.
Mathematical statistics is used in a wide variety of fields, including finance, healthcare, engineering, and social sciences. In finance, it is used to model financial markets and to make investment decisions. In healthcare, it is used to design clinical trials and to analyze patient data.
In engineering, it is used to design and test new products and processes. In social sciences, it is used to analyze survey data and to study human behavior.
Probability Theory
Probability theory is the branch of mathematics that deals with the likelihood of events. It provides a framework for quantifying the uncertainty associated with random events.
Probability theory is used in a wide variety of applications, including risk assessment, insurance, and gambling. In risk assessment, it is used to estimate the likelihood of natural disasters and other catastrophic events. In insurance, it is used to calculate premiums and to assess the risk of claims.
In gambling, it is used to calculate the odds of winning and to design fair games.
Statistical Inference
Statistical inference is the process of making inferences about a population based on a sample. It involves using statistical methods to estimate population parameters, such as the mean and variance, and to test hypotheses about the relationships between variables.
Statistical inference is used in a wide variety of applications, including market research, public health, and quality control. In market research, it is used to estimate the size and demographics of a target market. In public health, it is used to track the spread of diseases and to evaluate the effectiveness of public health interventions.
In quality control, it is used to monitor the quality of products and processes.
