Quizplus · Accepted Answer

The coefficient of determination is defined as the proportion of the variance in the dependent variable that is predictable from the independent variable(s). It is calculated by squaring the correlation coefficient and multiplying by 100. This gives a value between 0 and 100% that represents the percentage of variability in the dependent variable that can be explained by the independent variable(s). Therefore, option B is the correct answer.
