在Excel中计算单元格中数组结果的AVERAGE

Question

I have the below formula that Lookup the A1:A10 appropriated Score Number.

{=INDEX(Table1[ScoreNum],MATCH(A1:A10,Table1[ScoreWord],0))}

I need calculate the AVERAGE result of this entire array.

But when using this:

{=AVERAGE(INDEX(Table1[ScoreNum],MATCH(A1:A10,Table1[ScoreWord],0)))}

Returns the first looked up result with Index/Match, against returns the average of all returnable values whit this array formula.

How can do that?

The sample Workbook file

Sheet1

Sheet2: Table1

Note: The formula in B11 is: =AVERAGE(B1:B10) and returns the true value. I need return this without using the B helper column, directly in a single cell ( A11 ) with the true form of formula shows in the picture.

Very truly yours.

Answer 1

I would use, instead, this array-formula :

=AVERAGE(AVERAGEIF(Table1[Column1],A1:A10,Table1[Column2]))

To enter/confirm an array formula , hold down ctrl + shift while hitting enter . If you do this correctly, Excel will place braces {...} around the formula seen in the formula bar.

The AVERAGEIF function returns the array {1;0.8;1;0.2;0.6;0.8;1;1;0.6;0.2} which is what you are showing in your column B in your screenshot.

We then AVERAGE that array by nesting the AVERAGEIF(.. within the AVERAGE function.

Answer 2

Another method:

=AVERAGE(INDEX(Table1[Column2],N(IF({1},MATCH(A1:A10,Table1[Column1],0)))))

also entered as an array formula.
