如何在Excel中根據星期幾取平均值？

文檔平均每週 1

在Excel中，您是否嘗試過根據一周中的哪一天計算列表編號的平均值？ 假設我具有以下數據范圍，現在我想獲取所有星期一，工作日或週末的平均訂單。 本文，我將介紹一些公式來幫助您解決此任務。

使用公式計算基於星期幾的平均值

根據一周中的特定日期計算平均值

要獲取基於一周中特定日期的平均值，以下公式可能會對您有所幫助。 在此示例中，我將計算數據范圍中星期一的平均訂單，請執行以下操作：

請輸入以下公式： =AVERAGE(IF(WEEKDAY(D2:D15)=2,E2:E15)) 放入空白單元格，然後按 Shift + Ctrl + 輸入 鍵在一起以獲得正確的結果。 看截圖：

文檔平均每週 2

注意： 在上面的公式中：

D2：D15 是您基於的日期範圍；

數量 2 指示 星期一，並且1 =星期日，3 =星期二，4 =星期三…，您可以根據需要更改數字2；

E2：E15 指您想要獲得平均值的數據范圍。

保養竅門：以下公式也可以幫助您解決此問題： =SUMPRODUCT((WEEKDAY(D2:D15,2)=1)*E2:E15)/SUMPRODUCT((WEEKDAY(D2:D15,2)=1)*1) 然後按 Enter 獲得結果的關鍵。 （D2：D15 是您基於的日期範圍， E2：E15 指您想要獲得平均值的數據范圍，數字 1 指示 星期一，2 =星期二，3 =星期三...）

根據工作日計算平均值

如果要對所有工作日的平均訂單進行平均，請使用以下公式： =AVERAGE(IF(WEEKDAY(D2:D15,2)={1,2,3,4,5},E2:E15))，然後按 Shift + Ctrl + 輸入 鍵，您將獲得周一至週五的平均訂單。

文檔平均每週 3

筆記：

這是另一個公式，可能對您有利：=SUMPRODUCT((WEEKDAY(D2:D15,2)<6)*E2:E15)/SUMPRODUCT((WEEKDAY(D2:D15,2)<6)*1) 並按下 Enter 鍵。

2.在以上公式中： D2：D15 是您基於的日期範圍，並且 E2：E15 指您想要獲得平均值的數據范圍。

根據周末計算平均值

而且，如果您只想平均週末（星期六和星期日）的訂單，則以下公式可能會對您有所幫助：

請輸入以下公式： =AVERAGE(IF(WEEKDAY(D2:D15,2)={6,7},E2:E15)) 放入特定的空白單元格，然後按 Shift + Ctrl + 輸入 同時輸入關鍵字，然後您將僅在周末獲得平均訂單。 看截圖：

文檔平均每週 4

筆記：

1.您也可以使用以下公式解決此任務： =SUMPRODUCT((WEEKDAY(D2:D15,2)>5)*E2:E15)/SUMPRODUCT((WEEKDAY(D2:D15,2)>5)*1) 然後按Enter鍵。

2.在以上公式中： D2：D15 是您基於的日期範圍，並且 E2：E15 指您想要獲得平均值的數據范圍。

Hello, Manigandan
If you need to average from Monday to Friday and average from Saturday and Sunday, please apply the below formulas:
Average from Monday to Friday: =AVERAGE(IF(WEEKDAY(A2:A8,2)={1,2,3,4,5},D2:D8))
Average from Saturday and Sunday: =AVERAGE(IF(WEEKDAY(A2:A8,2)={6,7},D2:D8))
Note: Both the above fromulas are array formulas, please press Shift + Ctrl + Enter keys together to get the correct result.

How do I get my formula to work with it not taking zeros into the average?
=AVERAGE(IF(WEEKDAY($B$4:$B$34,2)={1,2,3,4,5},C4:C34))

Hello, Phil,
To get the average while skip the zeros, the following formula may help you:
=AVERAGE(IF((WEEKDAY($B$2:$B$14,2)<6)*($C$2:$C$14<>0)=1,$C$2:$C$14))

After pasting the formula, please press Ctrl + Shift + Enter keys together to get the result.

Please have a try, hope it can help you!

Yes, this works. Why does it work with such a large RANGE and not just for the number of days in a month?

Doing it my other way I had to manually change the formula's each month. THANK YOU 😀👊

I have this formula; {=AVERAGE(IF(WEEKDAY(I12:I25,2)={1,2,3,4,5},J12:J25))} the range: i12:i25(col 1 is the month date series) and j12:j25(col of values to be averaged) will change each day

Hello, Daniel
To solve your problem, you just need to adjust the cell references large as this:
=AVERAGE(IF(WEEKDAY(I12:I100000,2)={1,2,3,4,5},J12:J100000))
Please have a try, hope it can help you!

Hello, Daniel
Sorry, the above formula is not correct, plrase use the below formulas:
Average weekend: =AVERAGE(IF(IF(NOT(ISBLANK(B2:B10000)),WEEKDAY(A2:A10000,2)>5,FALSE),B2:B10000,FALSE))
Average workday: =AVERAGE(IF(IF(NOT(ISBLANK(B2:B10000)),WEEKDAY(A2:A10000,2)<6,FALSE),B2:B10000,FALSE))

Note: Both the formulas are array formulas, please press Ctrl + Shift + Enter keys together to get the result.

Please try, thank you!
