The Royal Badge of Wales, a coat of arms designed on behalf of the National Assembly for Wales, will feature on the banknotes alongside symbols representing the other three home nations.
Best Answer: It is possible for the standard deviation to be greater than the mean, even if all data points are positive numbers. However, the only way for this to happen is for most, if not all, data points to be at the extremes (with one extreme much greater in magnitude than the other) and nothing near the average.
Standard deviation is most usually measured in the same units as the mean. I suppose if you had a situation where spread was very small compared to mean you might use g for mean and mg for s.d. Standard deviation does not directly give you the maximum and minimum values although for many distributions these are each about three s.d. above and below the mean.
