Statistical analysis

Definition

Statistical analysis is the process of collecting, organizing, interpreting, and presenting data in order to uncover meaningful patterns and insights. This method involves using various statistical techniques and tools to evaluate data sets, which can lead to informed decision-making and predictions based on empirical evidence. By applying statistical analysis, one can better understand complex relationships between variables and assess trends, ultimately aiding in developing models or interpreting findings from research.
