某次考试20名学生的得分情况如下：
21 18 14 24 12 25 7 16 23 10
19 17 22 12 13 24 14 11 23 25
求平均值,中位数和众数.
7 10 11 12 12 13 14 14 16 17 18 19 21 22 23 23 24 24 25 25
平均值=(7+10+11+12+12+13+14+14+16+17+18+19+21+22+23+23+24+24+25+25)/20=17.5
中位数=(17+18)/2=17.5 (此题中,它正好等于平均数,这不是必然的.)
众数=12,14,23,24,25
--------------------------------------------------------------------
平均数、均值是一组数据的和除以这组数据的个数所得的平均值,也称为算术平均值.
中值（又称中位数）代表一个样本、种群或概率分布中的一个数值,其可将数值集合划分为相等的上下两部分.对于有限的数集,可以通过把所有观察值高低排序后找出正中间的一个作为中值.如果观察值有偶数个,则中值不唯一,通常取最中间的两个数值的平均数作为中值.
众数指一组数据中出现次数最多的数据.

大意如下：已知20名学生的得分，求中位数和众数。
从大到小排一下就好了
7 10 11 12 12 13 14 14 16 17
18 19 21 22 23 23 24 24 25 25
中位数是（17+18）/2=17.5
众数是12、14、23、24、25

全部展开

前面的两位都说了，偶就不验算了，
补充一下好了
提问：Find the mean, median and mode scores.
是要你找出平均数，中位数，和众数
其中
mean是指平均数，就是所有数的平均值，把所有数加起来除以总共有多少个数，就可以了
median是指中位数，就是把所有的数从大到小排或者从小到大排（其实一样的，一般从小到大比较符合大多数人数数的习惯），排在最中间的一个（注意，总共有奇数个数据的时候，很容易找到排在最中间的，但是如题目里面20个一样是偶数个的时候，最中间的有俩，那么加起来除以2）
mode是指这串数中出现最多的那个数，题目里面12，14，23，24，25各出现了2次，并列最多。。。所以都是mode
