Anscombe's quartet

Anscombe's quartet是由夏威夷大学马诺阿分校土木与环境工程系的Albert S. Kim教授分析的一组数据集，包含四个不同的数据集，每个数据集有11对数据点。这些数据集虽然在视觉上呈现不同的趋势，但具有相同的统计特性，如均值、方差和回归系数。数据集的创建过程涉及特定的算法，以确保这些统计参数的一致性。这些数据集主要用于教育和研究，特别是在统计学中，以展示数据可视化和定量统计的重要性，并解决数据集在统计上可能看似相同但在实际应用中表现不同的问题。

Anscombe's quartet is a set of datasets analyzed by Professor Albert S. Kim from the Department of Civil and Environmental Engineering, University of Hawaii at Manoa. It consists of four distinct datasets, each containing 11 pairs of data points. Although these datasets exhibit visually different trends, they share identical statistical properties including mean, variance, and regression coefficients. The creation of these datasets involved a specific algorithm to ensure the consistency of these statistical parameters. These datasets are primarily used for education and research, especially in the field of statistics, to demonstrate the importance of data visualization and quantitative statistics, and to address the issue that datasets may seem statistically identical but perform differently in practical applications.
