You have conducted pre- and post-test measures of the effectiveness of pay raises on employee productivity, measured as net $ sales for the month. Calculate the mean differences between the two time periods (as an absolute value) for the following 5 cases, with pre and post separated by a semi-colon:

a.Employee 1: 10000; 14000

b.Employee 2: 12000; 11000

c.Employee 3: 11000, 13000

d.Employee 4: 8000; 10000

e.Employee 5: 9000; 12000

Step-by-step explanation:

EmployeePre           Post        difference

 1              1000014000          4000

 2              1200011000         -1000

 3              11000         13000          2000

 4              8000         10000          2000

 5             9000         12000          3000

                                                    Total=10000

Mean difference =Total difference/number of employees

= 10,000 /5 = 2000

Mean difference = 2000.
