Noun1.coefficient of correlation- a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation); "what is the correlation between those two variables?" ...
An example of a strong negative correlation would be -0.97. The variables would move in opposite directions in a nearly identical move. The values demonstrate the strength of a relationship as the numbers approach 1 or -1. Numbers of 0.92 or -0.97 would show a strong positive and negative c...
The meaning of COEFFICIENT OF CONTRACTION is the ratio of the cross-sectional area of the first vena contracta to the area of the discharge aperture.
Unlike the coefficient of determination, the coefficient of correlation: A. indicates the percentage of variation explained by a regression model. B. measures the strength of association between the two variables more exactly. C. indicates whether the slope of the regression line is positive or nega...
A. weak positive correlation B. strong positive correlation C. weak negative correlation D. strong negative correlation 相关知识点: 试题来源: 解析 B。本题考查相关性系数的理解。相关性系数为 0.8,大于 0 且接近 1,表明是强正相关。A 选项弱正相关通常在 0.3 到 0.5 之间;C 选项弱负相关在 -0.3 ...
Although partial correlation is a correlation of residuals, the correlation of the true-score components of these residuals is not equivalent to the partial correlation of the true scores themselves. The source of this discrepancy is explained and its implications are briefly discussed....
"R" means the correlation coefficient, only in the range of-1 to +1. If the data closer to the +1, that they had a strong positive correlation. In contrast, if you are close to-1, to prove that they have a very strong negative correlation. There is also a number is equal to 0...
