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 a rough way, the standard deviation could be considered a measure of the extent to which one's observers agree or disagree with each another. The smaller the standard deviation suggests that people are in more agreement with one another than would be the case with a large standard deviation.
