B)only when all bivariate relationships are negative C)only when all bivariate relationships are zero D)only when the relationships are spurious

Quizplus · Accepted Answer

The coefficient of multiple determination (R²) is always greater than or equal to the squared value of any zero-order correlation coefficient. This is because R² represents the proportion of variance in the dependent variable that is explained by all of the independent variables in the model, while a zero-order correlation coefficient represents the proportion of variance in the dependent variable that is explained by a single independent variable.
