问题 Quantity A: n is an integer less than 1 the standard deviation of 1, 2, n
Quantity B: the standard deviation of 1, 2, 1
选项 A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案 A
解析 n为小于1的整数，那么显然1，2，n比1，2，1的分布要稀疏，更加远离平均值，因此1，2，n的标准方差比1，2，1的标准方差大，选择A。
