Calculate the coefficient of correlation, r, letting Row 1 represent the x-values and Row 2 represent the
y-values. Now calculate the coefficient of correlation, r, letting Row 2 represent the x-values and Row 1
represent the y-values. What effect does switching the explanatory and response variables have on the
correlation coefficient? $$\begin{array} { l | c | c | c | c | c | c | c | c | c | c | }
\text { Row 1 } & 1 & 3 & 10 & 7 & 5 & 4 & 6 & 8 & 9 & 2 \
\hline \text { Row 2 } & - 7 & 11 & 12 & 4 & 1 & - 3 & 2 & 6 & 9 & 11
\end{array}$$
