连续平均特定值 [英] averaging specific values in a row

问题描述

我对excel经验不足，所以这可能是一个基本问题，但我似乎找不到任何答案.

I'm fairly inexperienced with excel so this might be a bit of a basic question but I can't seem to find the answer anywhere.

我有几行，一个是索引"行，其他则包含值.我想获取基于索引的每一行的平均值(每个索引的平均值).

I have several rows, one is an "index" row while the others contain values. I want to get the averages for each row based on the indexes (average for each index).

我一直在查看AVERAGE函数中的IF函数，但似乎无法找出正确的语法，所以我想知道是否有可能?

I've been looking at the IF function inside an AVERAGE function but I can't seem to figure out the proper syntax so I'm wondering if it is even possible?

我试图对单个平均值这样做: = AVERAGE(IF(A3:J3 = 0; A5:M5; 0)).

I attempted to do it like so for a single average: =AVERAGE(IF(A3:J3=0;A5:M5;0)).

马上我可以看到几个问题.首先，对于每个正条件，我要说的是使用整个行(我不知道如何将一行映射到另一行).其次，对于每个负条件，我都提供一个0而不是忽略该值.

Straight away I can see a couple of problems. First for each positive conditional I am saying to use the entire row (I don't know how to map one row to another) as a result. Secondly for each negative conditional I provide a 0 rather than ignoring that value.

从我站着的地方看来，我需要做的事似乎不可能...我正确吗?

From where I'm standing it doesn't seem like what I need is possible to do...am I correct?

推荐答案

您可以结合使用 SUMIF 和 COUNTIF 函数来获得平均值:

You can combine SUMIF and COUNTIF functions to get the average:

=SUMIF(A1:K1,1,A2:K2) / COUNTIF(A1:K1, 1)

将给出您想要的索引1(在第1行，A到K列)和第2行中的值的平均值.

would give the average you want for index 1 (in row 1, columns A through K), values in row 2.
