Is the standard deviation of the salaries of Company Y’s employees greater
than the standard deviation of the salaries of Company Z’s employees?
(1) The average (arithmetic mean) salary of Company Y’s employees is
greater than the average salary of Company Z’s employees.
(2) The median salary of Company Y’s employees is greater than the
median salary of Company Z’s employees.
關於這題有關standard deviation,average, median 的關係比較,有沒有更清楚的想法
,感謝!!
