求平均数在数学和日常生话中有着广泛的应用,它的基本算法是用数据总和除以数据个数,即:平均数=总数÷总份数.这是求平均数的最基本的方法.此外,根据题目数据的特点,还有一些灵活、简便、巧妙的方法。一、基数法基数法就是选取一组数据中的最小数或最大数作为这组数
The average is widely used in mathematics and daily life, its basic algorithm is to use the sum of data divided by the number of data, namely: average = total ÷ total number of copies. This is the most basic method of averaging In addition, according to the characteristics of the subject data, there are some flexible, simple and clever methods. First, the cardinal number method is to select a group of data in the minimum or maximum number as the number of groups
