For this, I recommend you to always use the 3rd column approach and forget about the other way. It keeps things simpler. And yes, you should use the 3rd column also for the standard dev. | |

Yes my samples are highly correlated such that I get 0.986014 and 0.98846 for spearman and pearson coefficient, respectively. So if my two samples were independent then I could always say 𝐸(𝑥𝑦)=𝐸(𝑥)𝐸(1/𝑦). Then which method would give me a better result? | |
