md，median
median and selection
Examples
- One half of its values will be found below and one half above the median .
一半数值低于中位数，一半数值高于中位数。 - Add the frequencies in each class to find the class that contains that centermost element .
把每一组的频率逐组相加，找出包含中位数的那一组。 - To find the median of a data set, we first array the data in ascending or descending order .
为了计算一组数据的中位数，我们首先要把这些数据按由大到小或由小到大的顺序加以排列。 - We can find the median even when out data are qualitative descriptions like color or sharpness, rather than numbers .
资料不是数字资料而是象颜色、清晰度等品质指标时，我们也可以计算中位数。 - The median is not as highly influenced by the frequency of occurrence of a single value as is the mode, nor is it pulled by extreme values as is the mean .
中位数既不象众数那样受到数值出现次数的影响，又不象平均数那样随着特殊值的大小而偏移。
