题目
Which of the following correlation coefficients indicates the weakest linear relationship between two variables?
选项
A.–0.67
B.–0.24
C.0.33
答案
B
解析
： B is correct. Correlations near +1 exhibit strong positive linearity, whereas correlations near –1 exhibit strong negative linearity. A correlation of 0 indicates an absence of any linear relationship between the variables. The closer the correlation is to 0, the weaker the linear relationship. ： B正确。 相关系数在＋1附近表现出很强的正线性，而在-1附近表现出很强的负线性。相关性为0表示变量之间不存在任何线性关系。相关性越接近0，线性关系越弱。
