MATLAB: Statistical test for difference between means

statistics

Hi,

I have two mean values and standard errors (se) of two unknown distributions.

I would like to check whether the difference between these two means is statistically significant.

mean1=1.2545, se1=0.0145

mean2=1.6913, se2=0.0172

Thanks,

Aviram.

mean1=1.2545; se1=0.0145;
mean2=1.6913; se2=0.0172;
rho = 0.01;
s = 2*normcdf(-abs(mean1-mean2), 0, min(se1,se2))
s = 2.3405e-199
s < rho
ans = logical
