Comparing two sequence using mean and standard deviation

I have obtained means and standard deviations from six observations in two different groups.

group1: mean1=[10 14 15 12 8 6]; std1=[ 1 1.5 2 1.0 3.4 5.6];
group2: mean2=[-20 -5 -4 -10 -8 -13]; std2=[ 0.5 0.3 0.8 0.6 0.1 0.3] ;

Can someone please suggest me techniques that i can use in Matlab to show how well separated they are? In other words, i want to show that they are not correlated and therefore not similar:
