Short Answer

If the coefficient of correlation is −0.50, the percentage of the variation in the dependent variable y that is explained by the variation in the independent variable x is: $$\begin{array} { | l | l | } \hline \text { A. } & - 50 \% \\\hline \text { B. } & 25 \% . \\\hline \text { C. } & 50 \% \\\hline \text { D. } & - 25 \% . \\\hline\end{array}$$
