“R” the meaning correlation coefficient, only can in - 1 to +1 sectors in.If obtains the data even more approaches +1, explained they have the very strong relevance.On the contrary, if approaches - 1, proved they have the very strong inverse correlation.Also some one kind of situation...
The correlation coefficient (r) for measuring the connection between two variables (x and y) has been calculated as 0.6. How much of the variation in the dependent variable (y) is explained by the variation in the independent variable (x)?? 36%60%40%64% 相关知识点: 试题来源: 解析 ...

In simple linear regression analysis, the coefficient of correlation (or correlation coefficient) is a statistic which indicates an association between the independent variable and the dependent variable. The coefficient of correlation is represented by “r” and it has a range of -1.00 to +1.00. ...

Coefficient of Determination The coefficient of determination measures how much of the variation in the value ofycan be explained by the relationship betweenxandy. This value, as a percent, can be calculated withr2: Example: ifr=0.5then the coefficient of determination of the data ...
One problem with the correlation coefficient is similar to the problem with the odds ratio, the scale of measurement of r. As we know, the correlation coefficient ranges from −1.0 to 1.0 and thus has properties that do not allow the application of commonly used statistical methods. In meta...
