|Correlation coefficients;[数][物]相关系数；关联系数
相关系数（correlation coefficient）是统计学中用于量化两个变量之间线性关系强度与方向的指标，其取值范围在$-1$到$1$之间。数值越接近$1$或$-1$，表明变量间的相关性越强；数值为$0$时则表示无线性相关。
方向与强度
正相关系数（如$0.8$）表示变量同向变化，负值（如$-0.6$）则表明反向变化。例如，身高与体重常呈正相关，而气温与羽绒服销量可能呈负相关。
常见类型
$$ r = frac{sum (x_i - bar{x})(y_i - bar{y})}{sqrt{sum (x_i - bar{x}) sum (y_i - bar{y})}} $$ 参考来源：统计学基础教材。
相关系数广泛应用于心理学（如评估压力与睡眠质量的关系）、经济学（如分析GDP与失业率关联性）及医学研究（如研究药物剂量与疗效的关联）。世界卫生组织在分析流行病学数据时，也常以相关系数作为变量间关联强度的依据。
