I did a Spearman correlation test and I used 14 samples(12 form group 1 and 2 form group 2). P value =0.04. here is the plot:
I repeated the analysis for group 1 only (12 samples) and removed group 2 (2 data points). The significant is lost and p value become high p=o.11.
here is the second plot:
The question is: Is the loss of the significant p value because it was driven by 2 data points from group 2 or there is no enough power for the second analysis?. Can I conclude that there result is not significant as it was driven by 2 points for the first case(group 1 and 2 first plot)? your help is very appreciated.
