I read the question and the answers regarding the idea of the mean being equal to the standard deviation, in which the mean can always be adjusted to equal anything. But, if the data is restricted to only positive values, then it seems the normal distribution would not work, while the exponential distribution and Poisson would work. Any ideas?
Mean equal to standard deviation, with positive values

0The Poisson distribution has mean equal to variance, which is not the standard deviation unless both are $1$ (or $0$) – 2012-07-12
