Quantity A: The Standard Deviation of 1, 3, 5,7,9, 11, 13, 15, 17, 19
Quantity B: The Standard Deviation of 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
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
C
解析
如果做这道题目时把两边的值硬算出来的话,显然是不明智的。我们仔细观察一下这两个数列,第二个数列中的数对应项比第一个数列中的数都大1,那么根据标准方差的性质,这两个数列的standard deviation完全相等,所以选择C。
