Question

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.

Answer 1

2000 USD

Explanation:

a. Difference for employee 1: 14000 - 10000 = 4000

b. Difference for employee 2: 11000 - 12000 = -1000

c. Difference for employee 3: 13000 - 11000 = 2000

d. Difference for employee 4: 10000 - 8000 = 2000

e. Difference for employee 5: 12000 - 9000 = 3000

The absolute mean difference of 5 employees is

(4000 - 1000 + 2000 + 2000 + 3000)/5 = 10000/5 = 2000

So the average net increase of each employed in the past month is 2000 USD
