I have calculate mean (but I normalized the mean in percentage) of some data with Matlab and found the standard deviation as well.
Later, I calculated standard deviation+mean and standard deviation-mean! (standard deviations were normalized in percentage)
The weird thing is that I got mean+standard deviation, higher than 100% is that possible?
I cannot evaluate this result by myself, if it is correct (possible) or not?
What do you think?
