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.
In risk analysis, in which you use standard deviation as a proxy for risk, a standard deviation higher than the average means that you are willing to accept an outcome which is lower than the mean. e.g a portfolio expected return of 10% +/- standard deviation of 11% means there is a good chance you could lose money.
