I do have the following data <pre> TABLE A <B>Population Size | Type | Value</B> 340 | Control | .7+03[SD] 350 | Test | .015+.25[SD] </pre> Can I convert this to something like this? How ? <pre> TABLE B <B>Population Size | Type | Value</B> 340 | Control | 25 350 | Test | 33 </pre> If not how to I convert TABLE A into a Odds Ratio (based on Mean and SD only) thanks, Raj
