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.
The mean size and the standard deviation from that mean can be obtained directly from the statistics of the distribution. Here, the (absolute) standard deviation (or âhalfwidthâ) of the distribution can be compared to the mean, and a relative polydispersity = standard deviation / mean can be obtained.
