相关 Correlation and dependence
（重定向自Correlation matrix）
在概率论和统计学中，相关（Correlation，或称相关系数或关联系数），显示两个随机变量之间线性关系的强度和方向。在统计学中，相关的意义是用来衡量两个变量相对于其相互独立的距离。在这个广义的定义下，有许多根据数据特点而定义的用来衡量数据相关的系数。

![Several sets of (x, y) points, with the Pearson correlation coefficient of x and y for each set. Note that the correlation reflects the noisiness and direction of a linear relationship (top row), but not the slope of that relationship (middle), nor many aspects of nonlinear relationships (bottom). N.B.: the figure in the center has a slope of 0 but in that case the correlation coefficient is undefined because the variance of Y is zero.](/Images/godic/202501/06/Correlation_examples2.svg3400.png")
![Pearson/Spearman correlation coefficients between X and Y are shown when the two variables' ranges are unrestricted, and when the range of X is restricted to the interval (0,1).](/Images/godic/202501/06/Correlation_range_dependence.svg3400.png")

In statistics, dependence is any statistical relationship between two random variables or two sets of data. Correlation refers to any of a broad class of statistical relationships involving dependence, though in common usage it most often refers to the extent to which two variables have a linear relationship with each other. Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price.
