Essay

Calculate the coefficient of correlation, r, letting Row 1 represent the x-values and Row 2 represent they-values. Now calculate the coefficient of correlation, r, letting Row 2 represent the x-values and Row 1represent the y-values. What effect does switching the explanatory and response variables have on the linearcorrelation coefficient? $$\begin{array} { l | c | c | c | c | c | c | c | c | c | c | } \text { Row 1 } & - 10 & - 8 & - 1 & - 4 & - 6 & - 7 & - 5 & - 3 & - 2 & - 9 \\\hline \text { Row 2 } & 0 & 18 & 19 & 11 & 8 & 4 & 9 & 13 & 16 & 18\end{array}$$ 4 Determine whether a linear relation exists between two variables.
