A clinical psychologist is investigating whether the number of mistakes made by an employee can be
forecasted by the number of tasks an employee was busy with. She randomly assigned a different number of
tasks (of the same level of complexity) to each of eight participants. After a participant completed all assigned
tasks, the psychologist calculated the number of errors made. The data for all eight participants have been
listed in the table below:
Number of tasks performed
simultaneously
24762513
Number of errors made
01620102
The person correlation coefficient for the above data is:
O a. 0.6531
O b. - 0.6531
O c. 0.8081
O d. - 0.8081
O e. None of the above
