Statistical analysis is a technique used in artificial intelligence and machine learning to process, analyse and model data. This technique involves the use of statistical tools and techniques to identify patterns and trends in data, and to make inferences and predictions based on those patterns.

Statistical analysis is commonly used in scientific research to analyse and summarise experimental data, but it is also used in a variety of applications, such as fraud detection, business decision making, process optimisation and prediction of future events.

Statistical techniques used in statistical analysis include descriptive statistics, which involves the use of statistical measures to summarise and visualise data, and inferential statistics, which involves the use of sampling and hypothesis testing techniques to make inferences about a population from a sample.

Statistical analysis also uses statistical models to make predictions and decisions based on the data. These models can be linear or non-linear, and may include techniques such as regression, time series analysis and survival analysis.

Statistical analysis is a fundamental technique in artificial intelligence and machine learning, as it provides a solid foundation for data processing and analysis. It is also a valuable tool for decision-making and predicting future events, as it allows users to make accurate, data-driven inferences about future outcomes.
