Hi All,

Having some trouble identifying why this formula isn't working. Want to be able to get an average based of the day of the week. Was originally using the LEFT function in criteria range (ie MON, TUE etc) however swapped to a wildcard and still not returning a value.

=SUMIF(A:A,"Monday*",G:G)

Any help would be appreciated.


Cheers

Click the italics "fx" icon to the left of the formula bar to open the Functions Arguments dialog. Help is displayed for each argument.
You can't use that formula since the Dates are interpreted as Numbers and your formula is for Text. Hence, a Helper column should help.

Hope this does the trick:
Cell Formulas
RangeFormula
B2:B17B2=TEXT(VALUE(WEEKDAY(A2,1)),"DDDD")
D2:D8D2=UNIQUE(B2:B17)
A3:A17A3=A2+1
E2:E8E2=COUNTIF(B2:B17,D2)
Dynamic array formulas.

You can do it without a helper column if you use FILTER:

Cell Formulas
RangeFormula
E2:E8E2=ROWS(FILTER($B$2:$B$17,TEXT($A$2:$A$17,"dddd")=D2))
F2:F8F2=LET(f,FILTER($B$2:$B$17,TEXT($A$2:$A$17,"dddd")=D2),SUM(f)/ROWS(f))
A3:A17A3=A2+1

Awesome! I will have to learn that LET Function. Thanks!

Or try this in F2:

=AVERAGE(FILTER($B$2:$B$17,TEXT($A$2:$A$17,"dddd")=D2))
