**PsyDAG**, Friday, April 20, 2012 at 12:37pmThe expected (E) frequency for each cell is found by multiplying the column total by the row total and dividing by the grand total.

Then, for each cell you subtract the expected (E) from the observed (O), square that, and divide by the expected (E).

Add the calculated values of all the cells to get the Chi Square value. Evaluate in terms of you degrees of freedom (#rows-1)(#columns-1).

I hope this helps.
