本文介绍了分析两个定量变量之间关系的方法。讨论并说明了样品积矩相关系数和线性回归方程的计算和解释。讨论了这些技术的常见误用。描述了总体参数的检验和置信区间，并强调了基本假设的失败。
The present review introduces methods of analyzing the relationship between two quantitative variables. The calculation and interpretation of the sample product moment correlation coefficient and the linear regression equation are discussed and illustrated. Common misuses of the techniques are considered. Tests and confidence intervals for the population parameters are described, and failures of the underlying assumptions are highlighted.
