You are given the following four pieces of information about a training program: training will have an impact on performance for two years; 10 employees will be trained; the standard deviation of untrained employees in dollars is 100; and it costs $50 to train one employee. What must be the effect size so as to allow the program to break even?

Question

Quizplus · Accepted Answer

To break even, the cost of training 10 employees ($500) must be equal to the increased performance resulting from training. The effect size is defined as the difference in performance between trained and untrained employees, divided by the standard deviation of untrained employees. Let x be the effect size:
$500 = 10 * $50
$500 = 10 * x * $100
x = .25
