    mean+std

    Hi guys!

    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?

    That is incomprehensible, how did you normalise the mean exactly?
