3 | 32 |
Part (a)
Compute the Pearson correlation coefficient. (Round your answer to three decimal places.)
Part (b)
Multiply each measurement of drug use times 3 and recalculate the correlation coefficient. (Round your answer to three decimal places.)
Part (c)
Divide each measurement in half for time spent working and recalculate the correlation coefficient. (Round your answer to three decimal places.)
a)
correlation r='Sxy/(√Sxx*Syy) = | -0.849 |
b)
correlation r='Sxy/(√Sxx*Syy) = | -0.849 |
c)
correlation r='Sxy/(√Sxx*Syy) = | -0.849 |
correlation coefficient remains same for transforming variables linearly
