A. The geometric mean may be used to estimate the average return over a one -period time horizon because it is the average of one - period returns. B. The difference between the geometric mean and the arithmetic mean increases with an increase in variability between period- to- period obser...
Both Geometric Mean vs Arithmetic Mean are tools to calculate the returns on investment in finance and are also used in other applications such as economics and statistics. The arithmetic mean calculates by dividing the sum of the numbers by the number count. However, Geometric means take into ...
For a set of data, if we calculate both the arithmetic and geometric means, it is clear that geometric mean is either same or less than the arithmetic mean. Arithmetic mean is more appropriate to calculate the mean value of the outputs of a set of independent events. In other words, if...
The theorem says thata1a2. ..a_n≤(a_1+a_2+⋯+a_n)/n , with equality if andonly if, a_1=a_2=⋯=a_n In words: the geometric mean ofn positive numbers is never greater than their arithmeticmean, and the two means are equal if and only if, thenumbers are equal....
当不等式涉及自然数n时，可以使用数学归纳法来证明。首先验证n=1时的不等式成立，然后假设n=k时不等式成立，证明n=k+1时不等式也成立。反证法：假设不等式不成立，然后推导出矛盾或不可能的情况。例如，假设$frac{a+b}{2} < sqrt{ab}$，然后尝试推导出矛盾。排序不等式：对于一组数，按照某种...
