Statistical investigation is a scientific method for collecting, analyzing, and interpreting data, widely used in various fields. It not only helps us understand the patterns of data distribution but also allows for inference about the population characteristics from samples, providing a basis for decision-making. In practical applications, statistical investigation involves a variety of techniques and tools, such as probability sampling, hypothesis testing, regression analysis, etc. These methods ensure the accuracy and reliability of data analysis. Furthermore, with the advent of the big data era, statistical investigation plays an increasingly important role in handling massive amounts of data, becoming a significant force driving scientific research and social development.
