在输入新数字时，如何平均一列的最后5个值？

在Excel中，您可以使用“平均值”功能快速计算一列中最后5个值的平均值，但是，您不时需要在原始数据后面输入新的数字，并且您希望平均值会自动更改为输入新数据。 也就是说，即使不时添加数字，您也希望平均值始终反映数据列表的最后5个数字。

列的最后5个值的平均值，作为使用公式输入的新数字

以下数组公式可以帮助您解决此问题，请执行以下操作：

在空白单元格中输入以下公式：

=IF(COUNT(A:A),AVERAGE(INDEX(A:A,LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),MIN(5,COUNT(A1:A10000)))):A10000),"no data") (答： 是包含您使用的数据的列， A1：A10000 是动态范围，您可以根据需要扩展它，并且数量 5 表示最后一个n值。），然后按 Ctrl + Shift + Enter 键一起获得最后5个数字的平均值。 看截图：

文档平均最后 5-1

现在，当您在原始数据后面输入新数字时，平均值也会随之更改，请参见屏幕截图：

文档平均最后 5-2

备注：如果单元格列包含0个值，则要从最后0个数字中排除5个值，以上公式将不起作用，在这里，我可以向您介绍另一个数组公式，以获取最后5个非零值的平均值，请输入以下公式：

=AVERAGE(SUBTOTAL(9,OFFSET(A1:A10000,LARGE(IF(A1:A10000>0,ROW(A1:A10000)-MIN(ROW(A1:A10000))),ROW(INDIRECT("1:5"))),0,1)))，然后按 Ctrl + Shift + Enter 获得所需结果的键，请参见屏幕截图：

文档平均最后 5-3

Bonjour,

La formule ne fonctionnant pas chez moi, et ayant un fort besoin de l'avoir, j'ai creusé l'affaire.
Je ne comprenais pas pourquoi utiliser la fonction LARGE qui n'est là que si on cherche la plus grande valeur d'une colonne, qui n'est pas forcément dans les 5 derniers.

Donc, voici une formule simple (en français, mais vous trouverez facilement l'équivalent anglais) :
=MOYENNE(INDEX(A2:A1000;NB(A2:A1000)-5+1):A1000)

Hello Yves,

You can use the simple formula: =AVERAGE(OFFSET(A1,COUNT(A:A),0,-5)). Please have a try. Please see the attached picture.

Sincerely,
Mandy

25% x (r) = (n), rounded up to the next whole number = (a) then the top (a) race points are averaged together to get the total race points (p) for the week.

Example: 25%x9 = 2.25 rounded up to 3. Top 3 races of the 9 races are averaged to get the total points for the week.

How do I create a formula in excel for this?

Hello, I would like average the lowest 10 values of the last 20 added to a set of data. After reading this one here and another one of your examples, I now know how to average the lowest 10 values of 20 and how to grab only the last 20 values for averaging, but I need to combine them so I only average the lowest 10 values of the last and or most resent 20 add to the set of data. Please let me know if you can help, thank you JT.

=IF(COUNT(A:A),AVERAGE(INDEX(A:A,LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),MIN(5,COUNT(A1:A10000)))):A10000),"no data")

Does not work for me.

Here is my version:
=IF(COUNT(C:C),AVERAGE(INDEX(C:C,LARGE(IF(ISNUMBER(C2:C10000),ROW(C2:C10000)),MIN(5,COUNT(C2:C10000))))):C10000)

The error I get is: Wrong data type.

I tried the formual =IF(COUNT(A:A),AVERAGE(INDEX(A:A,LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),MIN(5,COUNT(A1:A10000)))):A10000),"no data") then did COMMAND RETURN on my Mac and the formula worked but it didn't average the lowest 10 of the last 20 values correctly.I would like to average the lowest 8 values of of the last or most recent 20 values in a dynamic range as I enter a new value every day. Any help would be greatly appreciated!

Hello, Don,To solve your problem, please apply the below array formula:=AVERAGE(SMALL(IF((A1:A10000<>0)*(IF(ISNUMBER(A1:A10000),ROW(A1:A10000))=LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20})),A1:A10000),{1,2,3,4,5,6,7,8}))
After inserting the formula, please press

Thank you! When I verify I do not get the correct value. My last 20 values are as follows: 0.0    0.2    8.9    2.9    8.1    8.1    8.1    5.3    8.1    0.4    6.6    -0.5    0.2    9.0    9.0    5.1    3.6    1.9    4.6    1.3Your array gives an average of 1.2 for the 8 lowest valuesMy average is 0.8 for the 8 lowest values.Not sure what went wrong?

I think it doesn't average zero. I tired <=> and that is not a solution.

Hi, Don,Yes, as you said, the formula exclude the 0s when averaging, if you want to average with 0s, please apply the below formula:=AVERAGE(SMALL(IF(ISNUMBER(A1:A10000)*(IF(ISNUMBER(A1:A10000),ROW(A1:A10000))=LARGE(IF(ISNUMBER(A1:A10000),ROW(A1:A10000)),{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20})),A1:A10000),{1,2,3,4,5,6,7,8}))
Please remember to press Ctrl + Shift + Enter keys together.
