Question

A clinical psychologist is investigating whether the number of mistakes made by an employee can be forecast 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	2	4	7	6	2	5	1	3
Number of errors made	0	1	6	2	0	1	0	2

State which variable is the independent variable (?) and which is the dependent variable (?).

Calculate Pearson’s correlation coefficient and interpret it.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
