Compute the Pearson correlation coefficient. (Round your answer to three decimal places.)
Part (b)
Multiply each measurement of interruptions times 3 and recalculate the correlation coefficient. (Round your answer to three decimal places.)
Part (c)
Divide each measurement in half for time spent "on task" and recalculate the correlation coefficient. (Round your answer to three decimal places.)
The statistical software output for this problem is:
Also,
Correlation coefficient doesn't depend on change of origin and scale. Hence,
a) r = -0.937
b) r = -0.937
c) r = -0.937
