Final answer:
The statement is True. The coefficient of determination, r², represents the proportion of total variation in the dependent variable that can be explained by the variation in the independent variable using the regression line.
Step-by-step explanation:
The statement is True. The coefficient of determination, r², measures the proportion of total variation in the dependent variable that can be explained by the variation in the independent variable using the regression line. When expressed as a percentage, r² represents the percentage of variation in y that can be explained by variation in x. For example, if r² is 0.75, it means that 75% of the variation in y can be explained by variation in x.
