问题描述

我想知道如何在我的数据透视表中添加加权平均数。实际上,我需要做以下计算: SUM(col1 * col2)/ SUM(col2)

I would like to know how to add a weighted average in my pivot table. In fact, I need to do the following calculation: SUM(col1 * col2)/SUM(col2).

我尝试使用计算的字段选项,但是当我输入我的公式时,我只需输出以下结果: SUM((col1 * col2)/ col2)等于 SUM(col1)

I tried to do it by using the calculated field option but when I enter my formula, I just have the following result as an output: SUM((col1 * col2)/col2) which is equal to SUM(col1).

推荐答案

你需要 1 计算字段,而 1 帮助列

You will need 1 calculated field, and 1 helper column

助手列

col3=col1*col2

字段:

CF=Col3/Col1

如果您尝试将辅助列作为计算字段,则它将与 col1 col2 ,然后将它们加在一起导致无意义的答案

If you try to do the helper column as a calculated field, it will sum col1 and col2, then multiply them together which results in a meaningless answer
