如果一组具有偶数分布,则在按照升序对数字进行排列后,通过取两个中间值的算术平均值找到算术中位数。
In case of a group having even number of distribution, Arithmetic Median is found out by taking out the Arithmetic Mean of two middle values after arranging the numbers in ascending order.

给定数字的算术中位数为 57.5。
The Arithmetic Median of the given numbers is 57.5.
如果一组具有奇数分布,则按照升序对数字进行排列后,算术中位数是中间的数字。
In case of a group having odd number of distribution, Arithmetic Median is the middle number after arranging the numbers in ascending order.
