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.
A smaller standard deviation indicates that more of the data is clustered about the mean. A larger one indicates the data are more spread out. Comparing the standard deviation to the mean will tell you different things depending on the data you are working with.
