http://www.geneseo.edu/~bearden/socl211/chisquareweb/chisquare.html This site says it is observed-expected/sqrt expected*row total proportion*column total proportion
And
http://www.brynmawr.edu/socialwork/GSSW/Vartanian/Handouts/Residual.pdf
This site says it is observed-expected/sqrt(expected (1-row proportion)(1-column proportion)
The only difference is that the second formula subtracts the proportions from 1.
So which one is correct?
