When your data is in place, and you're ready to do the calculation, just hit the "Calculate R" button, and the calculator will run various tests on your data - to make sure it is suitable for the Pearson statistic - and then spit out the correlation coefficient, together with a lot ...
即数据必须是连续型数据(continuous)」. Like other correlation coefficients,
the Pearson correlation coefficient, is a number between -1 and 1, where a value of 1 indicates a perfect positive correlation, a value of -1 indicates a perfect negative correlation, and a value of 0 indicates no correlation.
Exact- relevant only for the Spearman's rank correlation. When dealing with small sample sizes, neither the t-distribution nor the z-distribution provides a sufficiently accurate approximation. In this case, you should use the exact calculation, taken from a pre-calculated table. The p-values co...
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)2 Cosine相似度也是一种相似性度量，输出...
In this article, we will explore the concept of Pearson's correlation coefficient, its calculation, interpretation, and significance. To begin, let's understand what Pearson's correlation coefficient represents. It is a value ranging between -1 and 1, where -1 represents a perfect negative ...
Definition:The correlation coefficient, also commonly known as Pearson correlation, is a statistical measure of the dependence or association of two numbers. When two sets of numbers move in the same direction at the same time, they are said to have a positive correlation. When one series of ...

The relationship between the variables is obtained by the calculation of coefficients of correlation. There are a number of different coefficients, including Kendall's tau correlation coefficient and Spearman's rho correlation coefficient, but the most popular and widely used one is that of Pearson's...
It can be calculated as the Pearson correlation coefficient for the residuals from linear regressions of interested variables on controlled variables. From: International Encyclopedia of Education (Third Edition), 2010 About this pageSet alert
