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.
For example, a large standard deviation creates a bell that is short and wide while a small standard deviation creates a tall and narrow curve. To understand the probability factors of a normal distribution you need to understand the following ârulesâ: 1. The total area under the curve is equal to 1 (100%). 2. About 68% of the area under the curve falls within 1 standard deviation. 3. About 95% of the area under the curve falls within 2 standard deviations.
