[IPAC-List] Differences between d and adverse impact

[Joel Wiesen]

Can anyone suggest additions to the following?


The AI ratio is a function of more than the test itself.  It is a 
function of:

1. d: with lower d there will be less AI.  (This is a property of the 
test itself.)

2. selection ratio: with higher SR there will be less AI.  If you select 
all applicants, the AI ratio will be 1.

3. proportion minority applicants: with higher proportion minority 
applicants, there will be less AI.  With a completely minority applicant 
pool, there will be no AI.

4. variance of scores for the subgroups: higher variance may mean more 
people near the top of the list.  (This is a property of the test itself.)

5. skewness of scores for the subgroups: skew to the right may mean more 
people near the top of the list.  (This is a property of the test itself.)

Of course, both d and AI are a function of the applicant groups.


Thanks,
Joel
