nrg89 Posted June 17, 2014 Report Share Posted June 17, 2014 I'm an engineer, so you have to excuse me if this question is focused on math. I'm interested in any equations for these kinds of comparisons in economics because I've been googling forever. Here goes. Two people, A and B, are doing two completely different tasks. A already has the value "a" which measures her aptitude of performing tasks in general and B has the value "b" which measures the same thing for him respectively (lets call these two values "aptitude scores"). A succeeds at her tasks while the majority of people with the same aptitude scores fail, and b fails his task while the majority of people with the same aptitude scores succeed. How will the aptitude scores change? And can we also, based on these results, assign a "difficulty score" to these tasks? Are there any equations that adresses this problem? Where can I learn more about them? While I am looking for a solution to this problem I would also like to know where I could learn more. I'm thankful for all the help I can get!

Assuming that you want a log-normal result (Gaussian bell curve) the obvious solution is to call the test into question. Otherwise, you might want to rig a test that will want to give you a few extraordinary achievers to weed out the rest. In other words, there is no nartural assumption tha any test has to offer median success. This would be called 'Cauchy'-- to give a predictable, low-frequency highly-positive outcome Edited June 20, 2014 by frank harley Quote Link to comment Share on other sites More sharing options...
