A direct equation for adjusting d for measurement error. Can be made by rearranging the three above. @dingding_peng

so you want to plug in d, n1, n2, reliabilities and get corrected d?

I mean you could do that but it would only look more messy and not add any information, would it?

2*((d/sqrt(d^2 + ((n1 + n2)^2/(n1*n2))))/sqrt(rl1 * rl2)))/sqrt(1-((d/sqrt(d^2 + ((n1 + n2)^2/(n1*n2))))/sqrt(rl1 * rl2))^2

with rl1 and rl2 being the reliabilities. but if I was doing that in my code, I'd prefer multiple lines, way more readable

aaaah, okay! Now I see. I actually think that the multiple line solution is neater, don't think you can simplify much

Oh well. I'm not particularly good with algebra, so I'm not the right person ti ask to rearrange stuff without errors! :) @dingding_peng
