The median score for the class is [br] If the mean score for the juniors were known, which of the following could be calculated from the information given?
I The range of the scores for the seniors
II The median score for the juniors
III The mean score for the seniors
选项
A、None
B、I only
C、III only
D、I and II
E、II and III
答案
C
解析
若大学三年级学生的平均分数已知,那么根据给出的信息可以计算出下面哪一项? I 大学四年级学生分数的值域; II大学三年级学生分数的中数; III大学四年级学生分数的平均值
解:本题的正确答案是(C)。I无法判断,因为无法判断出四年级学生分数的最大值和最小值;II无法判断,因为无法知道每个大学三年级学生的分数;III可以判断,已知大学三年级学生的平均数,然后用所有学生分数的和减去大学三年级学生的平均数与8的积,最后再除以12即可得到大学四年级学生分数的平均值。
