|Correlation coefficients;[數][物]相關系數；關聯繫數
相關系數（correlation coefficient）是統計學中用于量化兩個變量之間線性關系強度與方向的指标，其取值範圍在$-1$到$1$之間。數值越接近$1$或$-1$，表明變量間的相關性越強；數值為$0$時則表示無線性相關。
方向與強度
正相關系數（如$0.8$）表示變量同向變化，負值（如$-0.6$）則表明反向變化。例如，身高與體重常呈正相關，而氣溫與羽絨服銷量可能呈負相關。
常見類型
$$ r = frac{sum (x_i - bar{x})(y_i - bar{y})}{sqrt{sum (x_i - bar{x}) sum (y_i - bar{y})}} $$ 參考來源：統計學基礎教材。
相關系數廣泛應用于心理學（如評估壓力與睡眠質量的關系）、經濟學（如分析GDP與失業率關聯性）及醫學研究（如研究藥物劑量與療效的關聯）。世界衛生組織在分析流行病學數據時，也常以相關系數作為變量間關聯強度的依據。
