If there is a high correlation between the two variables, it can be inferred that there is a causal relationship between the two variables C. A plus sign for the correlation coefficient indicates a negative correlation and a minus sign indicates a positive correlation D. The degree and direction...
A。相关系数(correlation coefficient)在统计学中衡量两个变量之间关系的强度和方向。选项 B 中“the difference between two sets of data”指的是两组数据的差异;选项 C 中“the proportion of one variable in the total”指的是一个变量在总量中的比例;选项 D 中“the average of a set of data”指的是...
【题目】Which of the following statements about the correlation coefficient is true?(A)The correlation coefficient and the slope of the regression line may haveopposite signs.(B)A correlation of 1 indicates a perfect cause-and-effect relationship between thevariables.(C) Correlations of +0.87 and...
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. the intercept must also be positive B. the coefficient of determination can be either negative or positive, depending on the value of the slope C. the regression equation could have either a positive or a negative slope D. the slope of the line must be positive ...
“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 between two variables is 0.8. This indicates a 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...
