在探索变量间关系的统计学工具箱中，皮尔逊相关系数（Pearson correlation coefficient）占据着核心地位，尤其适用于分析两个连续型数据（具备双变量正态分布）之间的关联强度。这个指标，通常以ρ（rho）表示，其公式为：ρ = (cov(x, y)) / (σx * σy)这里的cov(x, y)指的是x和y的协方差，...
How to perform a Pearson's Product-Moment Correlation in SPSS Statistics. Step-by-step instructions with screenshots using a relevant example to explain how to run this test, test assumptions, and understand and report the output.
公式1：d(X,Y)=∑i=1n(Xn−Yn)2 Pearson相关性系数（Pearson Correlation）是衡量向量相似度的一种方法。输出范围为-1到+1, 0代表无相关性，负值为负相关，正值为正相关。公式2：ρ(X,Y)=E[(X−μX)(Y−μY)]σXσY=E[(X−μX)(Y−μY)]∑i=1n(Xi−μX)2∑i=1n(Yi−μY)...
In subject area: Computer Science The Pearson correlation coefficient is defined as a measure of the strength of the linear relationship between two variables. It indicates how close the relationship is to 1 or -1 for a strong linear relationship, while 0 signifies no linear relationship between ...

The command for correlation is found at Analyze –> Correlate –> Bivariate i.e. The Bivariate Correlation CoefficientSPSSdialog box will be there: Select one of the variables that you want to correlate in the left-hand pane of the Bivariate Correlations dialog box and shift it into the Vari...
Statistical software packages such as SPSS create correlations matrices before you can blink your eyes. An example is shown below.Note that the diagonal elements (in red) are the correlations between each variable and itself. This is why they are always 1. Also note that the correlations ...
