问题 What is the median of the data given below? 80,19,82, 15, 72, 3

选项

答案 45.5

解析 The median is the middle value in an ordered set of values. Therefore, the first step is to put the numbers in order, as follows:
3, 15, 19, 72,80,82
Because the set includes an even number of values, take the average of the middle values:
19 + 72 = 91
91 + 2 = 45.5
