(???/???) * ??? = 23.1

The residual for the corresponding cell of the table is thus:

??? - 23.1 = 6.9.

Birth Weight

Smokes High Med Low Total

No Smoke 42 44 29 115

Smoke 13 31 30 74

Total 55 75 59 189

- Statistics help Please -
**MathGuru**, Monday, April 8, 2013 at 7:50pmE = (row total)(column total)/n

...where E is the expected cell count.

E = (74)(59)/189 = 23.1

Residual = 30 - 23.1 = 6.9

I hope this helps and is what you were asking.
