{词义辨析}

average, mean, median 这几个词都有“平均、平均数”之意。其区别是：average 是“平均”或“平均数”的意思。它指的是把两个或两个以上的数相加的和,除以相加的数的个数而得的商数。mean 有“平均”或“平均数”的意思,但实际上指的是最大数和最小数之间的中数,即把二者相加的和,除以2所得的商数。median 是“中位数”的意思,它指的是按大小次序排列的一列数字中居中间的位置的那个数。试体会下面两句中这三个词的含义。The average of a group of five workers earning respectively 3,4,5,8 and 10 dollars a day is six dollars a day whereas the median is 5 dollars. 有五个工人,每天分别挣钱3,4,5,8和10元,这组工人收入的平均数为每天6元,中间位是5元。The mean temperature for a day with a high of 56°and a low of 34° is 45°.某日的最高气温为56°,最低气温为34°,其平均气温为45°。
