Explanation:
The coefficient of determination (R-squared) measures the proportion of variance in the dependent variable that is explained by the independent variables in a regression model. In this case, with R-squared = 0.59, it means that 59% of the total variation in the dependent variable is explained by the three independent variables.
Key points:
Ultimate access to all questions.
In a problem involving three independent variables and one dependent variable, assume that the computed coefficient of determination is 0.59. This result means that:
A
59% of the total variation is explained by the dependent variable
B
The correlation coefficient is 0.59 as well
C
At least two of the three independent variables are highly correlated
D
59% of the total variation in the dependent variable is explained by the independent variables
